PHP 7.1.12 Released

preg_match

(PHP 4, PHP 5, PHP 7)

preg_matchEffectue une recherche de correspondance avec une expression rationnelle standard

Description

int preg_match ( string $pattern , string $subject [, array &$matches [, int $flags = 0 [, int $offset = 0 ]]] )

Analyse subject pour trouver l'expression qui correspond à pattern.

Liste de paramètres

pattern

Le masque à chercher, sous la forme d'une chaîne de caractères.

subject

La chaîne d'entrée.

matches

Si matches est fourni, il sera rempli par les résultats de la recherche. $matches[0] contiendra le texte qui satisfait le masque complet, $matches[1] contiendra le texte qui satisfait la première parenthèse capturante, etc.

flags

Le paramètre flags peut prendre l'une des valeurs suivantes :

PREG_OFFSET_CAPTURE
Si cette option est activée, toutes les sous-chaînes qui satisfont le masque seront aussi identifiées par leur offset. Notez que cela modifie la valeur de matches qui devient un tableau dont chaque élément est un tableau contenant la chaîne correspondant au masque à l'offset 0 ainsi que l'offset de la chaîne dans subject à l'offset 1.

offset

Normalement, la recherche commence au début de la chaîne subject. Le paramètre optionnel offset peut être utilisé pour spécifier une position pour le début de la recherche (en octets).

Note:

Utiliser le paramètre offset ne revient pas à passer substr($subject, $offset) à preg_match_all() à la place de la chaîne subject, car pattern peut contenir des assertions comme ^, $ ou (?<=x). Comparez :

<?php
$subject 
"abcdef";
$pattern '/^def/';
preg_match($pattern$subject$matchesPREG_OFFSET_CAPTURE3);
print_r($matches);
?>

L'exemple ci-dessus va afficher :

Array
(
)

avec cet exemple :

<?php
$subject 
"abcdef";
$pattern '/^def/';
preg_match($patternsubstr($subject,3), $matchesPREG_OFFSET_CAPTURE);
print_r($matches);
?>

produira :

Array
(
    [0] => Array
        (
            [0] => def
            [1] => 0
        )

)

Valeurs de retour

preg_match() retourne 1 si le pattern fourni correspond, 0 s'il ne correspond pas, ou FALSE si une erreur survient.

Avertissement

Cette fonction peut retourner FALSE, mais elle peut aussi retourner une valeur équivalent à FALSE. Veuillez lire la section sur les booléens pour plus d'informations. Utilisez l'opérateur === pour tester la valeur de retour exacte de cette fonction.

Historique

Version Description
5.3.6 Retourne FALSE si offset est plus grand que la taille de subject.
5.2.2 Les sous-masques nommés acceptent maintenant la syntaxe (?<name>) et (?'name') mais aussi (?P<name>). Les anciennes versions n'acceptaient que la syntaxe (?P<name>).

Exemples

Exemple #1 Trouve la chaîne "php"

<?php
// Le "i" après le délimiteur du pattern indique que la recherche ne sera pas sensible à la casse
if (preg_match("/php/i""PHP est le meilleur langage de script du web.")) {
    echo 
"Un résultat a été trouvé.";
} else {
    echo 
"Aucun résultat n'a été trouvé.";
}
?>

Exemple #2 Trouve le mot "web"

<?php
/* \b, dans le masque, indique une limite de mot, de façon à ce que le mot
 "web" uniquement soit repéré, et pas seulement des parties de mots comme
  dans "webbing" ou "cobweb" */
if (preg_match("/\bweb\b/i""PHP est le meilleur langage de script du web.")) {
    echo 
"Le mot a été trouvé.";
} else {
    echo 
"Le mot n'a pas été trouvé.";
}

if (
preg_match("/\bweb\b/i""PHP est le meilleur langage de script du web.")) {
    echo 
"Le mot a été trouvé.";
} else {
    echo 
"Le mot n'a pas été trouvé.";
}
?>

Exemple #3 Lire un nom de domaine dans une URL

<?php
// repérer le nom de l'hôte dans l'URL
preg_match('@^(?:http://)?([^/]+)@i',
    
"http://www.php.net/index.html"$matches);
$host $matches[1];

// repérer les deux derniers segments du nom de l'hôte
preg_match('/[^.]+\.[^.]+$/'$host$matches);
echo 
"Le nom de domaine est : {$matches[0]}\n";
?>

L'exemple ci-dessus va afficher :

Le nom de domaine est : php.net

Exemple #4 Utilisation des sous-masques nommés

<?php

$str 
'foobar: 2008';

preg_match('/(?P<name>\w+): (?P<digit>\d+)/'$str$matches);

/* Ceci fonctionne également en PHP 5.2.2 (PCRE 7.0) et suivants,
 * cependant, la syntaxe ci-dessus est recommandée pour des raisons
 * de compatibilités ascendantes */
// preg_match('/(?<name>\w+): (?<digit>\d+)/', $str, $matches);

print_r($matches);

?>

L'exemple ci-dessus va afficher :

Array
(
    [0] => foobar: 2008
    [name] => foobar
    [1] => foobar
    [digit] => 2008
    [2] => 2008
)

Notes

Astuce

N'utilisez pas preg_match() si vous voulez uniquement savoir si une chaîne est contenue dans une autre. Utilisez dans ce cas les fonctions strpos() ou strstr(), qui sont beaucoup plus rapides.

I noticed that in order to deal with UTF-8 texts, without having to recompile php with the PCRE UTF-8 flag enabled, you can just add the following sequence at the start of your pattern: (*UTF8)

for instance : '#(*UTF8)[[:alnum:]]#' will return TRUE for 'é' where '#[[:alnum:]]#' will return FALSE

found this very very useful tip after hours of research over the web directly in pcre website right here : http://www.pcre.org/pcre.txt
there are many further informations about UTF-8 support in the lib

hop that will help!

Sometimes its useful to negate a string. The first method which comes to mind to do this is: [^(string)] but this of course won't work. There is a solution, but it is not very well known. This is the simple piece of code on how a negation of a string is done:

(?:(?!string).)

?: makes a subpattern (see http://www.php.net/manual/en/regexp.reference.subpatterns.php) and ?! is a negative look ahead. You put the negative look ahead in front of the dot because you want the regex engine to first check if there is an occurrence of the string you are negating. Only if it is not there, you want to match an arbitrary character.

Hope this helps some ppl.

To validate directorys on Windows i used this:

if( preg_match("#^([a-z]{1}\:{1})?[\\\/]?([\-\w]+[\\\/]?)*$#i",$_GET['path'],$matches) !== 1 ){
    echo("Invalid value");
}else{
    echo("Valid value");
}

The parts are:

#^ and $i            Make the string matches at all the pattern, from start to end for ensure a complete match.
([a-z]{1}\:{1})?        The string may starts with one letter and a colon, but only 1 character for eachone, this is for the drive letter (C:)
[\\\/]?            The string may contain, but not require 1 slash or backslash after the drive letter, (\/)
([\-\w]+[\\\/]?)*    The string must have 1 or more of any character like hyphen, letter, number, underscore, and may contain a slash or back slash at the end, to have a directory like ("/" or "folderName" or "folderName/"), this may be repeated one or more times.

When using a 'bad words reject string' filter, preg_match is MUCH faster than strpos / stripos. Because in the other cases, you would need to do a foreach for each word. With efficient programming, the foreach is ONLY faster when the first word in the ban-list is found.

(for 12 words, 100,000 iterations, no word found)
stripos - Taken 1.4876 seconds.
strpos - Taken 1.4207 seconds.
preg_match - Taken 0.189 seconds.

Interesting fact:
With long words ('averylongwordtospitepreg'), the difference is only much less. Only about a 2/3rd of the time instead of 1/6th

<?php

$words
= array('word1', 'word2', 'word3', 'word4', 'word5', 'word6', 'word7', 'word8', 'word9', 'word10', 'word11', 'word12' );
$teststring = 'ThIs Is A tEsTsTrInG fOr TeStInG.';
$count = 100000;
$find = 0;

$start = microtime(TRUE);
for (
$i = 0; $i < $count; $i++) {
    foreach (
$words as $word) {
        if (
stripos($teststring, $word) !== FALSE) {
           
$find++;
            break;
        }
    }
}
echo
'stripos - Taken ' . round(microtime(TRUE) - $start, 4) . ' seconds.' . PHP_EOL;

$start = microtime(TRUE);
for (
$i = 0; $i < $count; $i++) {
    foreach (
$words as $word) {
        if (
strpos($teststring, $word) !== FALSE) {
           
$find++;
            break;
        }
    }
}
echo
'strpos - Taken ' . round(microtime(TRUE) - $start, 4) . ' seconds.' . PHP_EOL;

$start = microtime(TRUE);
$pattern = '/';
$div = '';
foreach (
$words as $word) {
   
$pattern .= $div . preg_quote($word);
   
$div = '|';
}
$pattern .= '/i';
//Pattern could easily be done somewhere else if words are static.
for ($i = 0; $i < $count; $i++) {
    if (
preg_match($pattern, $teststring)) {
       
$find++;
    }
}
$end = microtime(TRUE);
echo
'preg_match - Taken ' . round($end - $start, 4) . ' seconds.' . PHP_EOL;

I just learned about named groups from a Python friend today and was curious if PHP supported them, guess what -- it does!!!

http://www.regular-expressions.info/named.html

<?php
   preg_match
("/(?P<foo>abc)(.*)(?P<bar>xyz)/",
                      
'abcdefghijklmnopqrstuvwxyz',
                      
$matches);
  
print_r($matches);
?>

will produce:

Array
(
    [0] => abcdefghijklmnopqrstuvwxyz
    [foo] => abc
    [1] => abc
    [2] => defghijklmnopqrstuvw
    [bar] => xyz
    [3] => xyz
)

Note that you actually get the named group as well as the numerical key
value too, so if you do use them, and you're counting array elements, be
aware that your array might be bigger than you initially expect it to be.

Was working on a site that needed japanese and alphabetic letters and needed to
validate input using preg_match, I tried using \p{script} but didn't work:

<?php
$pattern
='/^([-a-zA-Z0-9_\p{Katakana}\p{Hiragana}\p{Han}]*)$/u'; // Didn't work
?>

So I tried with ranges and it worked:

<?php
$pattern
='/^[-a-zA-Z0-9_\x{30A0}-\x{30FF}'
        
.'\x{3040}-\x{309F}\x{4E00}-\x{9FBF}\s]*$/u';
$match_string = '印刷最安 ニキビ跡除去 ゲームボーイ';

if (
preg_match($pattern, $match_string)) {
    echo
"Found - pattern $pattern";
} else {
    echo
"Not found - pattern $pattern";
}
?>

U+4E00–U+9FBF Kanji
U+3040–U+309F Hiragana
U+30A0–U+30FF Katakana

Hope its useful, it took me several hours to figure it out.

Matching a backslash character can be confusing, because double escaping is needed in the pattern: first for PHP, second for the regex engine
<?php
//match newline control character:
preg_match('/\n/','\n');   //pattern matches and is stored as control character 0x0A in the pattern string
preg_match('/\\\n/','\n'); //very same match, but is stored escaped as 0x5C,0x6E in the pattern string

//trying to match "\'" (2 characters) in a text file, '\\\'' as PHP string:
$subject = file_get_contents('myfile.txt');
preg_match('/\\\'/',$subject);    //DOESN'T MATCH!!! stored as 0x5C,0x27 (escaped apostrophe), this only matches apostrophe
preg_match('/\\\\\'/',$subject);  //matches, stored as 0x5C,0x5C,0x27 (escaped backslash and unescaped apostrophe)
preg_match('/\\\\\\\/',$subject); //also matches, stored as 0x5C,0x5C,0x5C,0x27 (escaped backslash and escaped apostrophe)

//matching "\n" (2 characters):
preg_match('/\\\\n/','\\n');
preg_match('/\\\n/','\\n'); //same match - 3 backslashes are interpreted as 2 in PHP, if the following character is not escapeable

Because making a truly correct email validation function is harder than one may think, consider using this one which comes with PHP through the filter_var function (http://www.php.net/manual/en/function.filter-var.php):

<?php
$email
= "someone@domain .local";

if(!
filter_var($email, FILTER_VALIDATE_EMAIL)) {
    echo
"E-mail is not valid";
} else {
    echo
"E-mail is valid";
}

here is a small tool for someone learning to use regular expressions. it's very basic, and allows you to try different patterns and combinations. I made it to help me, because I like to try different things, to get a good understanding of how things work.

<?php
$search
= isset($_POST['search'])?$_POST['search']:"//";
$match = isset($_POST['match'])?$_POST['match']:"<>";

echo
'<form method="post">';
echo
's: <input style="width:400px;" name="search" type="text" value="'.$search.'" /><br />';
echo
'm:<input style="width:400px;" name="match" type="text" value="'.$match.'" /><input type="submit" value="go" /></form><br />';
if (
preg_match($search, $match)){echo "matches";}else{echo "no match";}

As I wasted lots of time finding a REAL regex for URLs and resulted in building it on my own, I now have found one, that seems to work for all kinds of urls:

<?php
    $regex
= "((https?|ftp)\:\/\/)?"; // SCHEME
   
$regex .= "([a-z0-9+!*(),;?&=\$_.-]+(\:[a-z0-9+!*(),;?&=\$_.-]+)?@)?"; // User and Pass
   
$regex .= "([a-z0-9-.]*)\.([a-z]{2,3})"; // Host or IP
   
$regex .= "(\:[0-9]{2,5})?"; // Port
   
$regex .= "(\/([a-z0-9+\$_-]\.?)+)*\/?"; // Path
   
$regex .= "(\?[a-z+&\$_.-][a-z0-9;:@&%=+\/\$_.-]*)?"; // GET Query
   
$regex .= "(#[a-z_.-][a-z0-9+\$_.-]*)?"; // Anchor
?>

Then, the correct way to check against the regex ist as follows:

<?php
      
if(preg_match("/^$regex$/", $url))
       {
               return
true;
       }
?>

I see a lot of people trying to put together phone regex's and struggling (hey, no worries...they're complicated). Here's one that we use that's pretty nifty. It's not perfect, but it should work for most non-idealists.

*** Note: Only matches U.S. phone numbers. ***
