fsockopen
(PHP 4, PHP 5)
fsockopen — Apre una connessione a un socket appartenente a un dominio Internet o Unix
Descrizione
int fsockopen
( string $hostname
, int $porta
[, int $errno
[, string $errstr
[, float $timeout
]]] )
Inizializza una connessione nel dominio Internet (AF_INET, usando TCP o UDP) o Unix (AF_UNIX). Per il dominio Internet, apre una connessione a un socket TCP verso l' hostname sulla porta port . hostname può essere in questo caso, sia un fully qualified domain name o un indirizzo IP. Per le connessioni UDP, è necessario specificare esplicitamente il protocollo, usando: 'udp://' come prefisso di hostname . Per il dominio Unix, hostname viene utilizzato come percorso verso il socket, in questo caso, porta deve essere impostato a 0. Il parametro opzionale timeout può essere usato per impostare un timeout in secondi per la chiamata di sistema connect.
A partire da PHP 4.3.0, se si è compilato con il supporto OpenSSL, si può prefissare hostname con 'ssl://' oppure 'tls://' per utilizzare una connessione client SSL o TLS su una connessione TCP/IP per connettersi all'host remoto.
fsockopen() restituisce un puntatore a file che può essere usato nelle altre funzioni orientate ai file (come fgets(), fgetss(), fputs(), fclose() e feof()).
Se la chiamata non ha successo, viene restituito FALSE e se gli argomenti opzionali errno e errstr sono presenti, vengono impostati a indicare l'errore a livello di sistema che è avvenuto nella chiamata alla funzione connect() del sistema operativo. Se il valore di errno restituito è 0 e la funzione restituisce FALSE, è un'indicazione che l'errore è avvenuto prima della chiamata di connect(). Questo è molto probabilmente legato ad un problema di inizializzazione del socket. Si noti che gli argomenti errno e errstr verranno sempre passati by reference.
A seconda dell'ambiente operativo, il dominio Unix o l'opzionale timeout della connect potrebbero non essere disponibili.
Il socket viene aperto di default in modo blocking. Si può passare al modo non-blocking usando socket_set_blocking().
Example #1 Esempio di fsockopen()
<?php
$fp = fsockopen ("www.php.net", 80, $errno, $errstr, 30);
if (!$fp) {
echo "$errstr ($errno)<br>\n";
} else {
fputs ($fp, "GET / HTTP/1.0\r\nHost: www.php.net\r\n\r\n");
while (!feof($fp)) {
echo fgets ($fp,128);
}
fclose ($fp);
}
?>
Example #2 Uso di connessione UDP
<?php
$fp = fsockopen("udp://127.0.0.1", 13, $errno, $errstr);
if (!$fp) {
echo "ERRORE: $errno - $errstr<br>\n";
} else {
fwrite($fp,"\n");
echo fread($fp, 26);
fclose($fp);
}
?>
Vedere anche pfsockopen(), socket_set_blocking(), socket_set_timeout(), fgets(), fgetss(), fputs(), fclose(), feof() e l'estensione Curl.Nota: Il parametro timeout è stato introdotto nel PHP 3.0.9 e il supporto UDP è stato aggiunto nel 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!

A code is better than the feof.

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);

$line = rtrim(fgets($fp, 1024));

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 )

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

The following function performs pop3 authentication. Returns NULL on error, or true/false to indicate username/password matching:
$address is the hostname of the server and $ssl is a boolean that indicates whether an SSL connection is requested.
<?php
function pop3authCheck($username, $password, $address, $ssl)
{
if ($ssl)
$uri="ssl://$address:995";
else
$uri="tcp://$address:110";
$fp=fsockopen($uri);
if (!$fp)
return(NULL);
$st=fgets($fp, 512);
if (substr($st, 0, 3)!="+OK")
{
fclose($fp);
return(NULL);
}
$st="USER $username\n";
if (fwrite($fp, $st)!=strlen($st))
{
fclose($fp);
return(NULL);
}
$st=fgets($fp, 512);
if (substr($st, 0, 3)!="+OK")
{
fclose($fp);
return(NULL);
}
$st="PASS $password\n";
if (fwrite($fp, $st)!=strlen($st))
{
fclose($fp);
return(NULL);
}
$st=fgets($fp, 512);
fclose($fp);
if (substr($st, 0, 3)=="+OK")
return(true);
else if (substr($st, 0, 4)=="+ERR")
return(false);
else
return(NULL);
}
?>

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
