PHP 7.1.0 Released

phpinfo

(PHP 4, PHP 5, PHP 7)

phpinfoAffiche de nombreuses informations sur la configuration de PHP

Description

bool phpinfo ([ int $what = INFO_ALL ] )

Affiche de nombreuses informations sur PHP, concernant sa configuration courante : options de compilation, extensions, version, informations sur le serveur, et l'environnement (lorsqu'il est compilé comme module), environnement PHP, informations sur le système, chemins, valeurs générales et locales de configuration, en-têtes HTTP et la licence PHP.

Comme tous les systèmes sont configurés différemment, phpinfo() sert généralement à vérifier la configuration ainsi que les variables prédéfinies, pour une plate-forme donnée.

phpinfo() est un bon outil de débogage, car il affiche le contenu de toutes les variables EGPCS (Environnement, GET, POST, Cookie, Serveur).

Liste de paramètres

what

L'affichage peut être personnalisé en utilisant une ou plusieurs des constantes suivantes. Elles sont combinables avec l'opérateur or, et doivent être passées dans le paramètre what. Vous pouvez aussi additionner ces constantes.

Options de phpinfo()
Nom de la constante Valeur Description
INFO_GENERAL 1 La ligne de configuration, le chemin du php.ini, la date de compilation, le serveur web, le système, etc.
INFO_CREDITS 2 Les crédits de PHP. Voir aussi phpcredits().
INFO_CONFIGURATION 4 Valeurs courantes locales et générales des directives PHP. Voyez aussi la fonction ini_get().
INFO_MODULES 8 Modules chargés et leur configuration spécifique. Voir aussi la fonction get_loaded_extensions().
INFO_ENVIRONMENT 16 Informations sur les variables d'environnement, qui sont disponibles dans la variable $_ENV.
INFO_VARIABLES 32 Affiche toutes les variables prédéfinies, issues de l'environnement, la méthode GET, la méthode POST, les cookies et le serveur.
INFO_LICENSE 64 La licence PHP. Voir aussi » la FAQ de la licence.
INFO_ALL -1 Affiche toutes les informations suscitées.

Valeurs de retour

Cette fonction retourne TRUE en cas de succès ou FALSE si une erreur survient.

Historique

Version Description
5.5.0 Le logo GUIDs a été remplacé par son URI ; aussi, la désactivation de expose_php n'a pas d'effet sur le résultat de la fonction phpinfo(). Les crédits sont également maintenant inclus dans l'affichage au lieu d'être simplement liés.
5.2.2 L'information "Loaded Configuration File" a été ajoutée, alors qu'avant, seule l'information "Configuration File (php.ini) Path" existait.

Exemples

Exemple #1 Exemple avec phpinfo()

<?php

// Affiche toutes les informations, comme le ferait INFO_ALL
phpinfo();

// Affiche uniquement le module d'information.
// phpinfo(8) fournirait les mêmes informations.
phpinfo(INFO_MODULES);

?>

Notes

Note:

Dans les versions antérieures à PHP 5.5, une partie des informations affichées sont désactivées si la directive expose_php est configurée avec la valeur off. Cela inclut les logos PHP et Zend, ainsi que les crédits.

Note:

phpinfo() affiche du texte au lieu de HTML lorsque vous utilisez la version CLI.

I needed a way to quickly scroll through the phpinfo which is a large list of information. so here it is. In the top there is a list with sections, the new section loaded extensions will hold the links to the anchors of the loaded modules. the section session variables will show the current loaded sessions. It's using Domdocument for manipulation so you should have that loaded:
<?php
ob_start
();
   
$exts = get_loaded_extensions();
   
phpinfo();
   
$phpinfo = ob_get_contents();
   
ob_end_clean();
   
//print $phpinfo;
   
$html_str = $phpinfo;
   
$html = new DOMDocument();
   
$html->loadHTML($html_str);
   
$title = $html->getElementsByTagName("title")->item(0);
   
$title->nodeValue = "PHP Version ".phpversion();
   
$body = $html->getElementsByTagName("body")->item(0);
   
   
$body->setAttribute("style", "background-color:beige;");
   
$table = $body = $html->getElementsByTagName("table")->item(3)->nextSibling;
   
$head  = $html->getElementsByTagName("table")->item(0)->nextSibling;
   
ob_start();
   
?>
    <h2><a name="session_variables">Session variables</a></h2>
    <table border="0" cellpadding="2" width="600">

Removes sensitive data like AUTH_USER and AUTH_PASSWORD from the phpinfo output:

<?php
// start output buffering
ob_start();

// send phpinfo content
phpinfo();

// get phpinfo content
$html = ob_get_contents();

// flush the output buffer
ob_end_clean();

// remove auth data
if (isset($_SERVER['AUTH_USER'])) $html = str_replace($_SERVER['AUTH_USER'], '<i>no value</i>', $html);
if (isset(
$_SERVER['AUTH_PASSWORD'])) $html = str_replace($_SERVER['AUTH_PASSWORD'], '<i>no value</i>', $html);

echo
$html;

After reading and trying various functions, I couldn't find one that correctly parses all the configurations, strips any left-over html tag and converts special characters into UTF8 (e.g. &#039; into '), so I created my own by improving on the existing ones:

function phpinfo2array() {
    $entitiesToUtf8 = function($input) {
        // http://php.net/manual/en/function.html-entity-decode.php#104617
        return preg_replace_callback("/(&#[0-9]+;)/", function($m) { return mb_convert_encoding($m[1], "UTF-8", "HTML-ENTITIES"); }, $input);
    };
    $plainText = function($input) use ($entitiesToUtf8) {
        return trim(html_entity_decode($entitiesToUtf8(strip_tags($input))));
    };
    $titlePlainText = function($input) use ($plainText) {
        return '# '.$plainText($input);
    };
   
    ob_start();
    phpinfo(-1);
   
    $phpinfo = array('phpinfo' => array());

    // Strip everything after the <h1>Configuration</h1> tag (other h1's)
    if (!preg_match('#(.*<h1[^>]*>\s*Configuration.*)<h1#s', ob_get_clean(), $matches)) {
        return array();
    }
   
    $input = $matches[1];
    $matches = array();

    if(preg_match_all(
        '#(?:<h2.*?>(?:<a.*?>)?(.*?)(?:<\/a>)?<\/h2>)|'.
        '(?:<tr.*?><t[hd].*?>(.*?)\s*</t[hd]>(?:<t[hd].*?>(.*?)\s*</t[hd]>(?:<t[hd].*?>(.*?)\s*</t[hd]>)?)?</tr>)#s',
        $input,
        $matches,
        PREG_SET_ORDER
    )) {
        foreach ($matches as $match) {
            $fn = strpos($match[0], '<th') === false ? $plainText : $titlePlainText;
            if (strlen($match[1])) {
                $phpinfo[$match[1]] = array();
            } elseif (isset($match[3])) {
                $keys1 = array_keys($phpinfo);
                $phpinfo[end($keys1)][$fn($match[2])] = isset($match[4]) ? array($fn($match[3]), $fn($match[4])) : $fn($match[3]);
            } else {
                $keys1 = array_keys($phpinfo);
                $phpinfo[end($keys1)][] = $fn($match[2]);
            }

        }
    }
   
    return $phpinfo;
}

The output looks something like this (note the headers are also included but are prefixed with '# ', e.g. '# Directive'):

big thanx 2 Mardy dot Hutchinson at gmail dot com
very good!

some fixes to correct result displaying:
1. we need to trim $matches [1], 'cause there can be empty lines;
2. not bad to remove <body> tag 'cause styles for it not apply correctly...
3. ...and change styles a little (remove "body" selector)

we need to change two lines:

<?php
preg_match
('%<style type="text/css">(.*?)</style>.*?(<body>.*</body>)%s', ob_get_clean(), $matches);
?>
to
<?php
preg_match
('%<style type="text/css">(.*?)</style>.*?<body>(.*?)</body>%s', ob_get_clean(), $matches);
?>

and

<?php
preg_split
( '/\n/', $matches[1] )
?>
to
<?php
preg_split
( '/\n/', trim(preg_replace( "/\nbody/", "\n", $matches[1])) )
?>

That's all! Now we have a really flexible addition to phpinfo();

One note on the very useful example by "jon at sitewizard dot ca". 
The following statements:
Statement 1:
$phpinfo[end(array_keys($phpinfo))][$match[2]] = isset($match[4]) ? array($match[3], $match[4]) : $match[3];
Statement 2:
$phpinfo[end(array_keys($phpinfo))][] = $match[2];

These two lines will produce the error "Strict Standards:  Only variables should be passed by reference in...".  The root of the error is in the incorrect use of the end() function. The code works but thows the said error.
To address this try using the following statements:

Statement 1 revision:
$keys = array_keys($phpinfo);
$phpinfo[end($keys)][$match[2]] = isset($match[4]) ? array($match[3], $match[4]) : $match[3];

Statement 2 revision:
$keys = array_keys($phpinfo);
$phpinfo[end($keys)][] = $match[2];

This fixes the error.
To wrap it all in an example:
<?php
function quick_dev_insights_phpinfo() {
ob_start();
phpinfo(11);
$phpinfo = array('phpinfo' => array());

    if(
preg_match_all('#(?:<h2>(?:<a name=".*?">)?(.*?)(?:</a>)?</h2>)|(?:<tr(?: class=".*?")?><t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>)?)?</tr>)#s', ob_get_clean(), $matches, PREG_SET_ORDER)){
        foreach(
$matches as $match){
        if(
strlen($match[1])){
           
$phpinfo[$match[1]] = array();
        }elseif(isset(
$match[3])){
       
$keys1 = array_keys($phpinfo);
       
$phpinfo[end($keys1)][$match[2]] = isset($match[4]) ? array($match[3], $match[4]) : $match[3];
        }else{
           
$keys1 = array_keys($phpinfo);
           
$phpinfo[end($keys1)][] = $match[2];     
           
        }
       
        }
}

    if(! empty(
$phpinfo)){
        foreach(
$phpinfo as $name => $section) {
            echo
"<h3>$name</h3>\n<table class='wp-list-table widefat fixed pages'>\n";
            foreach(
$section as $key => $val){
                    if(
is_array($val)){
                    echo
"<tr><td>$key</td><td>$val[0]</td><td>$val[1]</td></tr>\n";
                    }elseif(
is_string($key)){
                    echo
"<tr><td>$key</td><td>$val</td></tr>\n";
                    }else{
                    echo
"<tr><td>$val</td></tr>\n";
                }
            }
        }
            echo
"</table>\n";
        }else{
    echo
"<h3>Sorry, the phpinfo() function is not accessable. Perhaps, it is disabled<a href='http://php.net/manual/en/function.phpinfo.php'>See the documentation.</a></h3>";
    }
}
?>
Frankly, I went thought the trouble of adding this note because the example by "jon at sitewizard dot ca"  is probably the best on the web, and thought it unfortunate that it throws errors. Hope this is useful to someone.

A simple method to style your own phpinfo() output.

<style type="text/css">
#phpinfo {}
#phpinfo pre {}
#phpinfo a:link {}
#phpinfo a:hover {}
#phpinfo table {}
#phpinfo .center {}
#phpinfo .center table {}
#phpinfo .center th {}
#phpinfo td, th {}
#phpinfo h1 {}
#phpinfo h2 {}
#phpinfo .p {}
#phpinfo .e {}
#phpinfo .h {}
#phpinfo .v {}
#phpinfo .vr {}
#phpinfo img {}
#phpinfo hr {}
</style>

<div id="phpinfo">
<?php

ob_start
() ;
phpinfo () ;
$pinfo = ob_get_contents () ;
ob_end_clean () ;

// the name attribute "module_Zend Optimizer" of an anker-tag is not xhtml valide, so replace it with "module_Zend_Optimizer"
echo ( str_replace ( "module_Zend Optimizer", "module_Zend_Optimizer", preg_replace ( '%^.*<body>(.*)</body>.*$%ms', '$1', $pinfo ) ) ) ;

?>
</div>

Embedding phpinfo within your page, that already has style information:

The phpinfo output is wrapped within a <div class='phpinfodisplay'>, and we privatize all the style selectors that phpinfo() creates.

Yes, we cheat on preparing the selector list.

<?php
ob_start
();
phpinfo();

preg_match ('%<style type="text/css">(.*?)</style>.*?(<body>.*</body>)%s', ob_get_clean(), $matches);

# $matches [1]; # Style information
# $matches [2]; # Body information

echo "<div class='phpinfodisplay'><style type='text/css'>\n",
   
join( "\n",
       
array_map(
           
create_function(
               
'$i',
               
'return ".phpinfodisplay " . preg_replace( "/,/", ",.phpinfodisplay ", $i );'
               
),
           
preg_split( '/\n/', $matches[1] )
            )
        ),
   
"</style>\n",
   
$matches[2],
   
"\n</div>\n";
?>

Perhaps one day the phpinfo() function will be modified to output such a safe string on its own.

Hi.

Here my version of saving php_info into an array:

<?php
function phpinfo_array()
{
   
ob_start();
   
phpinfo();
   
$info_arr = array();
   
$info_lines = explode("\n", strip_tags(ob_get_clean(), "<tr><td><h2>"));
   
$cat = "General";
    foreach(
$info_lines as $line)
    {
       
// new cat?
       
preg_match("~<h2>(.*)</h2>~", $line, $title) ? $cat = $title[1] : null;
        if(
preg_match("~<tr><td[^>]+>([^<]*)</td><td[^>]+>([^<]*)</td></tr>~", $line, $val))
        {
           
$info_arr[$cat][$val[1]] = $val[2];
        }
        elseif(
preg_match("~<tr><td[^>]+>([^<]*)</td><td[^>]+>([^<]*)</td><td[^>]+>([^<]*)</td></tr>~", $line, $val))
        {
           
$info_arr[$cat][$val[1]] = array("local" => $val[2], "master" => $val[3]);
        }
    }
    return
$info_arr;
}

// example:
echo "<pre>".print_r(phpinfo_array(), 1)."</pre>";

To extract all of the data from phpinfo into a nested array:
<?php
ob_start
();
phpinfo();
$phpinfo = array('phpinfo' => array());
if(
preg_match_all('#(?:<h2>(?:<a name=".*?">)?(.*?)(?:</a>)?</h2>)|(?:<tr(?: class=".*?")?><t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>)?)?</tr>)#s', ob_get_clean(), $matches, PREG_SET_ORDER))
    foreach(
$matches as $match)
        if(
strlen($match[1]))
           
$phpinfo[$match[1]] = array();
        elseif(isset(
$match[3]))
           
$phpinfo[end(array_keys($phpinfo))][$match[2]] = isset($match[4]) ? array($match[3], $match[4]) : $match[3];
        else
           
$phpinfo[end(array_keys($phpinfo))][] = $match[2];
?>

Some examples of using individual values from the array:

<?php
   
echo "System: {$phpinfo['phpinfo']['System']}<br />\n";
    echo
"Safe Mode: {$phpinfo['PHP Core']['safe_mode'][0]}<br />\n";
    echo
"License: {$phpinfo['PHP License'][0]}<br />\n";
?>

To display everything:

<?php
   
foreach($phpinfo as $name => $section) {
        echo
"<h3>$name</h3>\n<table>\n";
        foreach(
$section as $key => $val) {
            if(
is_array($val))
                echo
"<tr><td>$key</td><td>$val[0]</td><td>$val[1]</td></tr>\n";
            elseif(
is_string($key))
                echo
"<tr><td>$key</td><td>$val</td></tr>\n";
            else
                echo
"<tr><td>$val</td></tr>\n";
        }
        echo
"</table>\n";
    }
?>

Note: In order to properly retrieve all of the data, the regular expression matches table headers as well as table data, resulting in 'Local Value' and 'Global Value' showing up as 'Directive' entries.

<?php

// NOTE: When accessing a element from the above phpinfo_array(), you can do:
$array = phpinfo_array();

// This will work
echo $array["General"]["System "]; 

// This should work also, but it doesn't because there is a space after System in the array.
 
echo $array["General"]["System"]; 

// I hope the coder will fix it, so as to save someone else from wasting time. Otherwise, nice script.

This is necessary to obtain a W3C validation (XHTML1.0 Transitionnal)...
phpinfo's output is declared with that DTD :
- "System ID" has the wrong url to validate : "DTD/xhtml1-transitional.dtd" rather than "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"
- Some module names contains space and the function's output use the name in anchors as ID and NAME. these attributes can't be validated like that (unique name only).

<?php

ob_start
();

ob_start ();                              // Capturing
phpinfo ();                               // phpinfo ()

$out = ob_get_clean ();

$pre = $doc->createElement ('div'); // or pre
$pre->setAttribute ('style', 'white-space: pre;'); // for a div element, useless with pre
$pre->appendChild ($doc->createTextNode ($out));
$body->appendChild ($pre);

$doc->formatOutput = true; // For a nice indentation
$doc->saveXML ();

?>

All that could be done with only RegExp but I prefer the use of DOM for manipulating documents

I wanted a simple *function* to convert the output of phpinfo into an array.  Here's what I came up with thanks to alot of the previous authors tips, and the source file: php-5.2.6/ext/standard/info.c

Call this function like phpinfo_array() prints the array, phpinfo_array(1) returns the array for your own processing.

== Sample Output ==
[PHP Configuration] => Array
(
  [PHP Version] => 5.2.6
  [PHP Egg] => PHPE9568F34-D428-11d2-A769-00AA001ACF42
  [System] => Linux askapache 2.6.22.19-grsec3
  [Build Date] => Nov 11 2008 13:09:07
  [Configure Command] =>  ./configure --prefix=/home/grsec/bin/php
  [Server API] => FastCGI

  [IPv6 Support] => enabled
[Zend Egg] => PHPE9568F35-D428-11d2-A769-00AA001ACF42
  [PHP Credits Egg] => PHPB8B5F2A0-3C92-11d3-A3A9-4C7B08C10000
)

[mbstring] => Array
(
  [mbstring.http_input] => pass
  [mbstring.internal_encoding] => Array
    (
     [0] => ISO-8859-1
     [1] => no value
    )

  [mbstring.language] => neutral
   )

[mcrypt] => Array
(
  [Version] => 3.5.7
  [Api No] => 20031217
)

<?php
function phpinfo_array($return=false){
/* Andale!  Andale!  Yee-Hah! */
ob_start();
phpinfo(-1);

$pi = preg_replace(
array(
'#^.*<body>(.*)</body>.*$#ms', '#<h2>PHP License</h2>.*$#ms',
'#<h1>Configuration</h1>#'"#\r?\n#", "#</(h1|h2|h3|tr)>#", '# +<#',
"#[ \t]+#", '#&nbsp;#', '#  +#', '# class=".*?"#', '%&#039;%',
 
'#<tr>(?:.*?)" src="(?:.*?)=(.*?)" alt="PHP Logo" /></a>'
 
.'<h1>PHP Version (.*?)</h1>(?:\n+?)</td></tr>#',
 
'#<h1><a href="(?:.*?)\?=(.*?)">PHP Credits</a></h1>#',
 
'#<tr>(?:.*?)" src="(?:.*?)=(.*?)"(?:.*?)Zend Engine (.*?),(?:.*?)</tr>#',
 
"# +#", '#<tr>#', '#</tr>#'),
array(
'$1', '', '', '', '</$1>' . "\n", '<', ' ', ' ', ' ', '', ' ',
 
'<h2>PHP Configuration</h2>'."\n".'<tr><td>PHP Version</td><td>$2</td></tr>'.
 
"\n".'<tr><td>PHP Egg</td><td>$1</td></tr>',
 
'<tr><td>PHP Credits Egg</td><td>$1</td></tr>',
 
'<tr><td>Zend Engine</td><td>$2</td></tr>' . "\n" .
 
'<tr><td>Zend Egg</td><td>$1</td></tr>', ' ', '%S%', '%E%'),
ob_get_clean());

$sections = explode('<h2>', strip_tags($pi, '<h2><th><td>'));
unset(
$sections[0]);

$pi = array();
foreach(
$sections as $section){
  
$n = substr($section, 0, strpos($section, '</h2>'));
  
preg_match_all(
  
'#%S%(?:<td>(.*?)</td>)?(?:<td>(.*?)</td>)?(?:<td>(.*?)</td>)?%E%#',
    
$section, $askapache, PREG_SET_ORDER);
   foreach(
$askapache as $m)
      
$pi[$n][$m[1]]=(!isset($m[3])||$m[2]==$m[3])?$m[2]:array_slice($m,2);
}

return (
$return === false) ? print_r($pi) : $pi;
}

One note on the above functions for cleaning up the phpinfo() HTML and throwing it into an array data structure. In order to catch all of the info tidbits the preg_match_all has to be tweaked to deal with 2 and 3 column tables.

I have changed the preg_match_all() here so that the last <td></td> is optional

<?php
function parsePHPConfig() {
   
ob_start();
   
phpinfo(-1);
   
$s = ob_get_contents();
   
ob_end_clean();
   
$a = $mtc = array();
    if (
preg_match_all('/<tr><td class="e">(.*?)<\/td><td class="v">(.*?)<\/td>(:?<td class="v">(.*?)<\/td>)?<\/tr>/',$s,$mtc,PREG_SET_ORDER))
        foreach(
$mtc as $v){
            if(
$v[2] == '<i>no value</i>') continue;
           
$a[$v[1]] = $v[2];
        }
    }
    return
$a;
}
?>

check out this cool and fantastic colourful phpinfo()!

<?php

ob_start
();
phpinfo();
$phpinfo = ob_get_contents();
ob_end_clean();

preg_match_all('/#[0-9a-fA-F]{6}/', $phpinfo, $rawmatches);
for (
$i = 0; $i < count($rawmatches[0]); $i++)
  
$matches[] = $rawmatches[0][$i];
$matches = array_unique($matches);

$hexvalue = '0123456789abcdef';

$j = 0;
foreach (
$matches as $match)
{

  
$r = '#';
  
$searches[$j] = $match;
   for (
$i = 0; $i < 6; $i++)
     
$r .= substr($hexvalue, mt_rand(0, 15), 1);
  
$replacements[$j++] = $r;
   unset(
$r);
}

for (
$i = 0; $i < count($searches); $i++)
  
$phpinfo = str_replace($searches, $replacements, $phpinfo);
echo
$phpinfo;
?>

here you can notice that these numeric values of phpinfo
are similar to certain things in the binary system:

-1, coded in 7 digits:
111 1111

look at this:
1+2+4+8+16+32+64=127

unsigned,127 is:
111 1111

so, take a look at this: the way to get all function is to add all of them. zero is nothing.-1 is all.
so you can pass option with a negative number.
for example:
<?php phpinfo(48) ?>
is also:
<?php phpinfo(-80) ?>
48 = 32 + 16
-80= 0 - 64 - 8 - 4 - 2 - 1

so you can see in negative mode it like that:
not nothing
not all (-1) don't forget it !
not option 64
not option 8
not option 4
not option 2

so, that's good if you don't want option 8, you will do this:
not nothing(0)
not all(-1)
not option 8(-1)
you got:
<?php phpinfo(-9); ?>

hope this will be useful, that's my 1rst post ^^

This function parses the phpinfo output to get details about a PHP module.

<?php
/** parse php modules from phpinfo */
function parsePHPModules() {
ob_start();
phpinfo(INFO_MODULES);
$s = ob_get_contents();
ob_end_clean();

$s = strip_tags($s,'<h2><th><td>');
$s = preg_replace('/<th[^>]*>([^<]+)<\/th>/',"<info>\\1</info>",$s);
$s = preg_replace('/<td[^>]*>([^<]+)<\/td>/',"<info>\\1</info>",$s);
$vTmp = preg_split('/(<h2>[^<]+<\/h2>)/',$s,-1,PREG_SPLIT_DELIM_CAPTURE);
$vModules = array();
for (
$i=1;$i<count($vTmp);$i++) {
  if (
preg_match('/<h2>([^<]+)<\/h2>/',$vTmp[$i],$vMat)) {
  
$vName = trim($vMat[1]);
  
$vTmp2 = explode("\n",$vTmp[$i+1]);
   foreach (
$vTmp2 AS $vOne) {
   
$vPat = '<info>([^<]+)<\/info>';
   
$vPat3 = "/$vPat\s*$vPat\s*$vPat/";
   
$vPat2 = "/$vPat\s*$vPat/";
    if (
preg_match($vPat3,$vOne,$vMat)) { // 3cols
    
$vModules[$vName][trim($vMat[1])] = array(trim($vMat[2]),trim($vMat[3]));
    } elseif (
preg_match($vPat2,$vOne,$vMat)) { // 2cols
    
$vModules[$vName][trim($vMat[1])] = trim($vMat[2]);
    }
   }
  }
}
return
$vModules;
}
?>

Sample Output:
[gd] => Array
(
  [GD Support] => enabled
  [GD Version] => bundled (2.0.28 compatible)
  [FreeType Support] => enabled
  [FreeType Linkage] => with freetype
  [FreeType Version] => 2.1.9
  [T1Lib Support] => enabled
  [GIF Read Support] => enabled
  [GIF Create Support] => enabled
  [JPG Support] => enabled
  [PNG Support] => enabled
  [WBMP Support] => enabled
  [XBM Support] => enabled
)

[date] => Array (
  [date/time support] => enabled
  [Timezone Database Version] => 2005.14
  [Timezone Database] => internal
  [Default timezone] => America/Los_Angeles
  [Directive] => Array (
     [0] => Local Value
     [1] => Master Value
  )
  [date.timezone] => Array (
     [0] => no value
     [1] => no value
  )
)


<?php
/** get a module setting */
function getModuleSetting($pModuleName,$pSetting) {
$vModules = parsePHPModules();
return
$vModules[$pModuleName][$pSetting];
}
?>

Example: getModuleSetting('gd','GD Version'); returns "bundled (2.0.28 compatible)"

This is a slight modification to the previous code by "code at adspeed dot com" that extracts the PHP modules as an array. I used it on PHP 4.1.2 and it failed as the <h2> tags also had an align="center". So this update changes the regex for those tags:

<?php

/* parse php modules from phpinfo */

function parsePHPModules() {
ob_start();
phpinfo(INFO_MODULES);
$s = ob_get_contents();
ob_end_clean();

$s = strip_tags($s,'<h2><th><td>');
$s = preg_replace('/<th[^>]*>([^<]+)<\/th>/',"<info>\\1</info>",$s);
$s = preg_replace('/<td[^>]*>([^<]+)<\/td>/',"<info>\\1</info>",$s);
$vTmp = preg_split('/(<h2[^>]*>[^<]+<\/h2>)/',$s,-1,PREG_SPLIT_DELIM_CAPTURE);
$vModules = array();
for (
$i=1;$i<count($vTmp);$i++) {
  if (
preg_match('/<h2[^>]*>([^<]+)<\/h2>/',$vTmp[$i],$vMat)) {
  
$vName = trim($vMat[1]);
  
$vTmp2 = explode("\n",$vTmp[$i+1]);
   foreach (
$vTmp2 AS $vOne) {
  
$vPat = '<info>([^<]+)<\/info>';
  
$vPat3 = "/$vPat\s*$vPat\s*$vPat/";
  
$vPat2 = "/$vPat\s*$vPat/";
   if (
preg_match($vPat3,$vOne,$vMat)) { // 3cols
    
$vModules[$vName][trim($vMat[1])] = array(trim($vMat[2]),trim($vMat[3]));
   } elseif (
preg_match($vPat2,$vOne,$vMat)) { // 2cols
    
$vModules[$vName][trim($vMat[1])] = trim($vMat[2]);
   }
   }
  }
}
return
$vModules;
}
?>

Building on SimonD's elegant example to hide the logged-in username and password, which otherwise appear in plain text, the following should work for PHP 5.4+:

<?php
   
// start output buffering
   
ob_start();

   
// send phpinfo content
   
phpinfo();

   
// get phpinfo content
   
$html = ob_get_contents();

   
// flush the output buffer
   
ob_end_clean();

   
// remove auth data
   
if ( isset( $_SERVER[ 'PHP_AUTH_USER' ] ) ) $html = str_replace( $_SERVER[ 'PHP_AUTH_USER' ], '[ protected ]' , $html);
    if ( isset(
$_SERVER[ 'PHP_AUTH_PW' ] ) ) $html = str_replace( $_SERVER[ 'PHP_AUTH_PW' ], '[ protected ]' , $html);

    echo
$html;
?>

To remove additional items, just add them as above.
