If you are trying to use a raw socket with SSL support that supports client verification, use stream_context_create() in conjunction with stream_socket_client(). This will allow you to set advanced SSL options for a nonblocking socket connection.
fsockopen
(PHP 4, PHP 5)
fsockopen — Ouvre une socket de connexion Internet ou Unix
Description
Initialise une connexion par socket à la ressource spécifiée par hostname .
PHP supporte les cibles dans les domaines Internet et Unix comme décrit dans Liste des modes de transport de sockets disponibles. Une liste des types de transports peut également être trouvée en utilisant la fonction stream_get_transports().
La socket sera ouverte par défaut en mode bloquant. Vous pouvez changer de mode en utilisant : stream_set_blocking().
Liste de paramètres
- hostname
-
Si vous avez compilé le support OpenSSL, vous pouvez préfixer le paramètre hostname avec soit 'ssl://' soit 'tls://' pour utiliser une connexion SSL ou TLS avec le client à travers TCP/IP pour connecter l'hôte distant.
- port
-
Le numéro du port.
- errno
-
Si fourni, contient le numéro de l'erreur système qui survient lors de l'appel système à connect().
Si la valeur retournée par errno est 0 et que la fonction retourne FALSE, ce peut être une indication laissant penser que l'erreur est survenue avant l'appel à connect(). La plupart du temps, cela est du à un problème d'initialisation du socket.
- errstr
-
Le message d'erreur, sous la forme d'une chaîne de caractères.
- timeout
-
Le délai d'attente maximal, en secondes.
Note: Si vous avez besoin de définir un délai limite pour lire/écrire des données à travers cette socket, utilisez la fonction stream_set_timeout(), comme le paramètre timeout de la fonction fsockopen() uniquement appliqué lors de la connexion de la socket.
Valeurs de retour
fsockopen() retourne un pointeur de fichier qui peut être utilisé avec d'autres fonctions fichiers, telles fgets(), fgetss(), fputs(), fclose() et feof(). Si l'appel échoue, la fonction retourne FALSE.
Historique
| Version | Description |
|---|---|
| 4.3.0 | Ajout du support du paramètre timeout sous les systèmes win32. |
| 4.3.0 | Ajout du support SSL et TLS via TCP/IP. |
| 4.0.0 | Ajout du support UDP. |
| 3.0.9 | Ajout du paramètre timeout . |
Exemples
Exemple #1 Exemple avec fsockopen()
<?php
$fp = fsockopen("www.example.com", 80, $errno, $errstr, 30);
if (!$fp) {
echo "$errstr ($errno)<br />\n";
} else {
$out = "GET / HTTP/1.1\r\n";
$out .= "Hôte : www.example.com\r\n";
$out .= "Connexion : Fermée\r\n\r\n";
fwrite($fp, $out);
while (!feof($fp)) {
echo fgets($fp, 128);
}
fclose($fp);
}
?>
Exemple #2 Utilisation d'une connexion UDP
L'exemple ci-dessous décrit comment lire la date et l'heure grâce à un service UDP "daytime" (port 13), sur votre propre machine.
<?php
$fp = fsockopen("udp://127.0.0.1", 13, $errno, $errstr);
if (!$fp) {
echo "ERREUR : $errno - $errstr<br />\n";
} else {
fwrite($fp, "\n");
echo fread($fp, 26);
fclose($fp);
}
?>
Notes
Note: Suivant les environnements, le type 'domaine Unix' ou l'option timeout ne sont pas toujours disponibles.
Les sockets UDP semblent quelques fois avoir été ouvertes sans erreur, même si l'hôte distant n'est pas accessible. L'erreur apparaît alors uniquement lorsque vous tentez de lire/écrire sur la socket. La raison de cela est que UDP est un protocole "connectionless", ce qui signifie que le système ne tentera pas d'établir un lien pour la socket tant qu'il ne doit pas recevoir/envoyer de données.
Note: Lors de la spécification d'adresses IPv6 au format numérique (e.g. fe80::1) vous devez placer l'adresse IP entre crochets. Par exemple : tcp://[fe80::1]:80.

Re:
i found that it was '; ' (that's semicolon followed by a space) that permitted multiple cookies, not \r\n
i determined this by using charles http proxy, and inspecting the request headers for requests i was generating.
so the final cookie would header would look like
GET /path/to/script.php
Host: www.domain.com
Cookie: cookie_1=hello; cookie_2=world; cookie_3=bye;\r\n

For those of you trying to POST cookies, use the header:
"Cookie: cookiename=cookievalue\r\n";
I haven't tried this for multiple cookies, I would assume you just add another Cookies: line to your header var.

Of course, copy() is the ultimate download function, but it saves the data in a file, and probably you can use fopen() to get it as a string, but this function double checks everything, and has support for $http_response_header and
unlike file_get_contents(), it works on php 4.0.0
(Oh, and by the way, if you use it in another function like i do, don't forget to declare $http_response_header as global, or you won't be able to see the variable, even though you called it in the function)

Make a ping test with PHP
The problem with fsockopen is you have to known the destination port.
A real ping function could be :
function php_ping($url) {
$addr=parse_url($url);
$host=$addr['host'];
exec("ping -c 1 -w 1 $host", $list);
if (strpos($list[4],"1 received")>0) {
return true ;
}
return false;
}
But if your router refuse the ping ... the result will be always false > you may test both (fsockopen and ping)

After several days of trying to get telnet going from php 5.2, i've come up with http://www.dali.net.nz/Telnet.class.php.txt
based on the one found at http://cvs.adfinis.ch/cvs.php/phpStreamcast/telnet.class.php
example usage:
<?php
$telnet = new Telnet('telnethost.example.com');
$telnet->login('username', 'password');
echo $telnet->exec('ifconfig') . "\n";
echo $telnet->exec('ls -lh') . "\n";
$telnet->disconnect();

A pretty crude, but somewhat useful force-ping of the nearest network may come in handy for other mediocre coders like me. It returns an array of all replying boxes according to your $port choice (where, for reference, 139 targets all network cards and 3306 only running mysql apps). Keep the $timeout under 1 and the function can run in-under a second. Obvious limitations apply.
$ip = implode(".", array_slice(explode(".", $_SERVER["SERVER_ADDR"]), 0, 3)) . ".";
for ($i =0; $i < 255; $i++)
if (@fsockopen($ip . $i, $port, $err, $errstr, $timeout))
$online[] = $ip . $i;
The function can be expanded with additional for-loops, but I can't see the direct purpose of pinging everything-there-is.

I don't know why it's not mentioned here (or am I missing something), but the DEFAULT stream timeout is set according to default_socket_timeout in your php.ini file. Took forever for me to dig that up....

For those of you trying to POST cookies, use the header:
"Cookie: cookiename=cookievalue\r\n";
I haven't tried this for multiple cookies, I would assume you just add another Cookies: line to your header var.

I was having trouble doing an https in fopen and with fsockopen where the address had ssl://. I was getting error code 114 in the log. After much research i found that there was some ssl conflict trouble with MySQL 5.0.20-5.0.33. It had some functions that were interfering with openssl that showed up in the php install.

I ran into a problem where I needed to make an fsockopen() style connection from one specific ip address on a server with multiple ip aliases. Unfortunately fsockopen() does not allow the specification of a source address making it unsuitable. I could not find any other solutions elsewhere so here is mine for those with php 5.1.0 or greater.
// connect to the internet using the '192.168.0.100' IP
$opts = array('socket' => array('bindto' => '192.168.0.100:0'));
$context = stream_context_create($opts);
$fp = stream_socket_client("tcp://www.example.com:80", $errno, $errstr, 30, STREAM_CLIENT_CONNECT, $context);
Now $fp can be used like a resource handle returned by a vanilla fsockopen() call!

easy get UIDL.
A code is better than the feof.

fread($fp,1024);
fputs($fp, "USER $user\r\n");
fread($fp,1024);
fputs($fp, "PASS $pass\r\n");
fread($fp,1024);
fputs($fp, "UIDL\r\n");
fgets($fp,1024);
do {
$line = rtrim(fgets($fp, 1024));
if ($line == '.') break;
list(, $UIDL) = split(' ', $line, 2);
echo $UIDL;

Just a correction
The function decode_jbr at ya-right dot com work nice for me (thanks), but is missing a last case, for when the response is not chunked (because it's too short for exemple), here a corrected function :
function decode_body ( $info, $str, $eol = "\r\n" )
{
$tmp = $str;
$add = strlen ( $eol );
$str = '';
if ( isset ( $info['transfer-encoding'] ) && $info['transfer-encoding'] == 'chunked' )
{
do
{
$tmp = ltrim ( $tmp );
$pos = strpos ( $tmp, $eol );
$len = hexdec ( substr ( $tmp, 0, $pos ) );
if ( isset ( $info['content-encoding'] ) )
{
$str .= gzinflate ( substr ( $tmp, ( $pos + $add + 10 ), $len ) );
}
else
{
$str .= substr ( $tmp, ( $pos + $add ), $len );
}
$tmp = substr ( $tmp, ( $len + $pos + $add ) );
$check = trim ( $tmp );
}
while ( ! empty ( $check ) );
}
else if ( isset ( $info['content-encoding'] ) )
{
$str = gzinflate ( substr ( $tmp, 10 ) );
}
else {
$str = $tmp;
}
return $str;
}
HTTP/1.1 requires that all clients support chunked transfer encoding. If you don't want to implement that and just want something simple, make HTTP/1.0 requests instead:
<?php
...
fputs("GET $path HTTP/1.0\r\n");
fputs("Host: $host\r\n");
...etc..
?>

Handling chunked data needs careful handling, because the data can also be compressed inside the chunked data, and chunked data can have many parts, so you need to watch for that. Here a simple example that uses one function decode_header(); to build the header into a key => value array, so it makes it easy to test for the content and transfer types inside the decode_body(); function!
<?php
function decode_header ( $str )
{
$part = preg_split ( "/\r?\n/", $str, -1, PREG_SPLIT_NO_EMPTY );
$out = array ();
for ( $h = 0; $h < sizeof ( $part ); $h++ )
{
if ( $h != 0 )
{
$pos = strpos ( $part[$h], ':' );
$k = strtolower ( str_replace ( ' ', '', substr ( $part[$h], 0, $pos ) ) );
$v = trim ( substr ( $part[$h], ( $pos + 1 ) ) );
}
else
{
$k = 'status';
$v = explode ( ' ', $part[$h] );
$v = $v[1];
}
if ( $k == 'set-cookie' )
{
$out['cookies'][] = $v;
}
else if ( $k == 'content-type' )
{
if ( ( $cs = strpos ( $v, ';' ) ) !== false )
{
$out[$k] = substr ( $v, 0, $cs );
}
else
{
$out[$k] = $v;
}
}

$out[$k] = $v;

Sorry for multiple submission of this but Added @ to suppress errors and a few exmples:
Also note that this script checks specific ports so you need to have the correct port open on the server for this to work.
E.g if i have a windows domain controller and it is servering LDAP then the following would be used to check it is online:
chkServer("MyDC", "389");
for a webserver
chkServer("MyWebSvr", "80");
etc etc
--------------------------------------------------------
// check if a server is up by connecting to a port
function chkServer($host, $port)
{
$hostip = @gethostbyname($host); // resloves IP from Hostname returns hostname on failure
if ($hostip == $host) // if the IP is not resloved
{
echo "Server is down or does not exist";
}
else
{
if (!$x = @fsockopen($hostip, $port, $errno, $errstr, 5)) // attempt to connect
{
echo "Server is down";
}
else
{
echo "Server is up";
if ($x)
{
@fclose($x); //close connection (i dont know if this is needed or not).
}
}

here is my contribution for parsing chunked data.
please note: this function simply handles the RESPONSE, not the HEADERS, it would be your job to check the headers for 'Transfer-Encoding: chunked' field:
<?php
function parseChunked($response) {
$do = true;
$return = "";
$size = NULL;
while($do) {
// suppress warnings w/ @ if offset not in string (past end)
$pos = @strpos($response, "\r\n", 0);
if(!($pos === false) && $size === NULL) {
// we found CRLF, get len from hex
$size = hexdec(substr($response, 0, $pos));
// get the actual chunk-len, reset $response, $size
$return .= substr($response, $pos+2, $size);
$response = substr($response, ($pos+2) + $size);
$size = NULL;
}
else {
$do = false;
} // end if/else
} // end while
return $return;
} // end function parseChunked()
?>
Any recomendations or improvements please post
I've had issues with some of the handlers for chunked http 1.1 responses. Here's a method that worked for me, if it works for you as well, then cheers :P
<?php
function httpSocketConnection($host, $method, $path, $data)
{
$method = strtoupper($method);
if ($method == "GET")
{
$path.= '?'.$data;
}
$filePointer = fsockopen($host, 80, $errorNumber, $errorString);
if (!$filePointer)
{
logEvent('debug', 'Failed opening http socket connection: '.$errorString.' ('.$errorNumber.')<br/>\n');
return false;
}
$requestHeader = $method." ".$path." HTTP/1.1\r\n";
$requestHeader.= "Host: ".$host."\r\n";
$requestHeader.= "User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1) Gecko/20061010 Firefox/2.0\r\n";
$requestHeader.= "Content-Type: application/x-www-form-urlencoded\r\n";
if ($method == "POST")
{
$requestHeader.= "Content-Length: ".strlen($data)."\r\n";
}
$requestHeader.= "Connection: close\r\n\r\n";
if ($method == "POST")
{
$requestHeader.= $data;
}
fwrite($filePointer, $requestHeader);
$responseHeader = '';
$responseContent = '';
do
{
$responseHeader.= fread($filePointer, 1);
}
while (!preg_match('/\\r\\n\\r\\n$/', $responseHeader));
if (!strstr($responseHeader, "Transfer-Encoding: chunked"))
{
while (!feof($filePointer))
{
$responseContent.= fgets($filePointer, 128);
}
}
else
{
while ($chunk_length = hexdec(fgets($filePointer)))
{
$responseContentChunk = '';
logEventToTextFile('debug', $chunk_length);
$read_length = 0;
while ($read_length < $chunk_length)
{
$responseContentChunk .= fread($filePointer,
