fsockopen
(PHP 4, PHP 5)
fsockopen — Otevře socketové spojení v internetové nebo unixové doméně.
Popis
resource fsockopen ( string $target [, int $port [, int &$errno [, string &$errstr [, float $timeout]]]] )Iniciuje proudové spojení v internetové (AF_INET, za použití TCP nebo UDP) nebo unixové (AF_UNIX) doméně. Pro internetovou doménu otevře TCP kanál na stroj hostname na port port. hostname v takovém případě může být plně určené doménové jméno nebo IP adresa. Pro spojení UDP musíte explicitně specifikovat protokol předřazením 'udp://' před hostname. V unixové doméně se hostname použije jako cesta k socketu port se pak musí nastavit na 0. Nepovinný parametr timeout se může použít k nastavení time-outu pro systémové volání connect.
Od PHP 4.3.0, pokud jste PHP zkompilovali s podporou OpenSSL, můžete před hostname předřadit 'ssl://' nebo 'tls://' pro použití SSL nebo TSL spojení na vzdálený stroj přes TCP/IP.
fsockopen() vrací deskriptor souboru, který lze použít s jinými souborovými funkcemi (např. fgets(), fgetss(), fputs(), fclose() a feof()).
Pokud volání selže, vrací funkce FALSE, a pokud jsou přítomny nepovinné parametry errno a errstr, budou nastaveny na aktuální chybovou úroveň v systémovém volání connect(). Je-li vrácená hodnota v errno rovna 0 a funkce vrátila FALSE, znamená to, že chyba nastala před voláním connect(). Nejčastěji je to kvůli problému při inicializaci socketu. Uvědomte si, že argumenty errno a errstr se vždy předávají odkazem.
V závislosti na prostředí nemusí být k dispozici unixová doména nebo volitelný parametr timeout.
Socket se implicitně otevře v blokujícím režimu. Do neblokujícího režimu ho můžete přepnout použitím socket_set_blocking().
Příklad 1328. fsockopen() Příklad
<?php
$fp = fsockopen ("www.example.com", 80, $errno, $errstr, 30);
if (!$fp) {
echo "$errstr ($errno)<br>\n";
} else {
fputs ($fp, "GET / HTTP/1.0\r\nHost: www.example.com\r\n\r\n");
while (!feof($fp)) {
echo fgets ($fp,128);
}
fclose ($fp);
}
?>
Další (níže uvedený) příklad ukazuje, jak získat datum a čas z UDP služby "daytime" (port 13) na vašem vlastním počítači.
Příklad 1329. Použití UDP spojení
<?php
$fp = fsockopen("udp://127.0.0.1", 13, $errno, $errstr);
if (!$fp) {
echo "CHYBA: $errno - $errstr<br>\n";
} else {
fwrite($fp,"\n");
echo fread($fp, 26);
fclose($fp);
}
?>
Viz také pfsockopen(), socket_set_blocking(), socket_set_timeout(), fgets(), fgetss(), fputs(), fclose(), feof() a rozšíření Curl.Poznámka: Parametr timeout by zaveden v PHP 3.0.9 a podpora UDP v PHP 4.

When you try to POST/GET requests via HTTPS over SSL/TLS you should notice this:
<?php
// preconditions
$port = 80 | 443
$host = "www.example.com";
$method = "POST" | "GET";
$contenttype = "text/html" | "text/plain" | "text/xml" | ...;
$data = "<something>";
// script
if($port == 443)
$sslhost = "ssl://".$host;
else
$sslhost = $host;
$fp = fsockopen($sslhost, $port);
fputs($fp, "$method $path HTTP/1.1\r\n");
fputs($fp, "Host: $host\r\n");
fputs($fp, "Content-type: $contenttype\r\n");
fputs($fp, "Content-length: ".strlen($data)."\r\n");
fputs($fp, "Connection: close\r\n");
fputs($fp, "\r\n");
?>
The server usually does not understand the HTTP-header "Host: XXX" if you provide it with the trailing "ssl://" used by fsockopen(); If you do it anyway you probably get a HTTP 400 back as response. :-)

Make a ping test with PHP
The problem with fsockopen is you have to known the destination port.
A real ping function could be :
<?php
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();

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....

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.
<?php
// 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.
<?php

if ($fp > 0) {
fread($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 $UIDL;
} while ($line != '.');
fputs($fp, "QUIT\r\n");

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..

[EDIT by danbrown AT php DOT net: This note contains a big-fixed version of the user function decode_body(). Fix by (martjean77 at hot dot sapm dot mail dot com) [sic].]
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' )
{

$out[$k] = substr ( $v, 0, $cs );

{
$out[$k] = $v;

$out[$k] = $v;

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:
<?php
chkServer("MyDC", "389");
?>
for a webserver:
<?php
chkServer("MyWebSvr", "80");
?>
etc etc
--------------------------------------------------------
<?php
// 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
}

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 had a problem receving a "Content-Transfer: chunked" response i tried some prior codes but i had some problems too and i decided to code my own (it post something and receive the response although it's chunked). I hope you enjoy...
<?php
function doPost($uri,$postdata,$host){
$da = fsockopen($host, 80, $errno, $errstr);
if (!$da) {
echo "$errstr ($errno)<br/>\n";
echo $da;
}
else {
$salida ="POST $uri HTTP/1.1\r\n";
$salida.="Host: $host\r\n";
$salida.="User-Agent: PHP Script\r\n";
$salida.="Content-Type: application/x-www-form-urlencoded\r\n";
$salida.="Content-Length: ".strlen($postdata)."\r\n";
$salida.="Connection: close\r\n\r\n";
$salida.=$postdata;
fwrite($da, $salida);
while (!feof($da))
$response.=fgets($da, 128);
$response=split("\r\n\r\n",$response);
$header=$response[0];
$responsecontent=$response[1];
if(!(strpos($header,"Transfer-Encoding: chunked")===false)){
$aux=split("\r\n",$responsecontent);
for($i=0;$i<count($aux);$i++)
if($i==0 || ($i%2==0))
$aux[$i]="";
$responsecontent=implode("",$aux);
}//if
return chop($responsecontent);
}//else
