fsockopen

(PHP 4, PHP 5)

fsockopen — Open Internet or Unix domain socket connection

Description

resource fsockopen ( string $hostname [, int $port= -1 [, int &$errno [, string &$errstr [, float $timeout= ini_get("default_socket_timeout") ]]]] )

Initiates a socket connection to the resource specified by hostname .

PHP supports targets in the Internet and Unix domains as described in List of Supported Socket Transports. A list of supported transports can also be retrieved using stream_get_transports().

The socket will by default be opened in blocking mode. You can switch it to non-blocking mode by using stream_set_blocking().

Parameters

hostname

If you have compiled in OpenSSL support, you may prefix the hostname with either ssl:// or tls:// to use an SSL or TLS client connection over TCP/IP to connect to the remote host.

port

The port number.

errno

If provided, holds the system level error number that occurred in the system-level connect() call.

If the value returned in errno is 0 and the function returned FALSE, it is an indication that the error occurred before the connect() call. This is most likely due to a problem initializing the socket.

errstr

The error message as a string.

timeout

The connection timeout, in seconds.

Note: If you need to set a timeout for reading/writing data over the socket, use stream_set_timeout(), as the timeout parameter to fsockopen() only applies while connecting the socket.

Return Values

fsockopen() returns a file pointer which may be used together with the other file functions (such as fgets(), fgetss(), fwrite(), fclose(), and feof()). If the call fails, it will return FALSE

Errors/Exceptions

Throws E_WARNING if hostname is not a valid domain.

Changelog

Version Description
4.3.0 Added support for the timeout parameter on win32.
4.3.0 SSL and TLS over TCP/IP support was added.
4.0.0 UDP support was added.

Examples

Example #1 fsockopen() Example

<?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 .= "Host: www.example.com\r\n";
    $out .= "Connection: Close\r\n\r\n";
    fwrite($fp, $out);
    while (!feof($fp)) {
        echo fgets($fp, 128);
    }
    fclose($fp);
}
?>

Example #2 Using UDP connection

The example below shows how to retrieve the day and time from the UDP service "daytime" (port 13) in your own machine.

<?php
$fp = fsockopen("udp://127.0.0.1", 13, $errno, $errstr);
if (!$fp) {
    echo "ERROR: $errno - $errstr<br />\n";
} else {
    fwrite($fp, "\n");
    echo fread($fp, 26);
    fclose($fp);
}
?>

Notes

Note: Depending on the environment, the Unix domain or the optional connect timeout may not be available.

Warning

UDP sockets will sometimes appear to have opened without an error, even if the remote host is unreachable. The error will only become apparent when you read or write data to/from the socket. The reason for this is because UDP is a "connectionless" protocol, which means that the operating system does not try to establish a link for the socket until it actually needs to send or receive data.

Note: When specifying a numerical IPv6 address (e.g. fe80::1), you must enclose the IP in square brackets—for example, tcp://[fe80::1]:80.

When downloading large files, it is not really efficient to put the whole server answer in memory before parsing the data to remove the header parts. Here is a simple way to do it while writing the data as it arrive:

<?php

// $socket is a valid fsockopen handle

$out = '';
$headerendfound = false;
$fp = fopen($fileTarget, 'w');
$buffer = '';
while (!feof($socket)) {
    $out = fgets ($socket,16384);
    if ($headerendfound) {
        fwrite($fp, $out);
        print '.';
    }
    if (!$headerendfound) {
        $buffer .= $out;
        print "searching for header\n";
        $headerend = strpos($buffer, "\r\n\r\n");
        if ($headerend !== false) {
            $headerendfound = true;
            fwrite($fp, substr($buffer, $headerend+4));
            $buffer = '';
        }
    }
}
fclose($fp);
fclose($socket);

look at this smart ssl/http fsockopen function as a good solution for dealing with things

<?php
function _get($type,$host,$port='80',$path='/',$data='') {
    $_err = 'lib sockets::'.__FUNCTION__.'(): ';
    switch($type) { case 'http': $type = ''; case 'ssl': continue; default: die($_err.'bad $type'); } if(!ctype_digit($port)) die($_err.'bad port');
    if(!empty($data)) foreach($data AS $k => $v) $str .= urlencode($k).'='.urlencode($v).'&'; $str = substr($str,0,-1);
   
    $fp = fsockopen($host,$port,$errno,$errstr,$timeout=30);
    if(!$fp) die($_err.$errstr.$errno); else {
        fputs($fp, "POST $path HTTP/1.1\r\n");
        fputs($fp, "Host: $host\r\n");
        fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n");
        fputs($fp, "Content-length: ".strlen($str)."\r\n");
        fputs($fp, "Connection: close\r\n\r\n");
        fputs($fp, $str."\r\n\r\n");
       
        while(!feof($fp)) $d .= fgets($fp,4096);
        fclose($fp);
    } return $d;
}

I've been searching a big while before considering that it was impossible to use context with fsockopen, as it was in PHP4.

If you want to use sockets with tls or ssl encryption and certificates and so on, you'd better have a look to stream_socket_client.

To just take the HTTP content from fsockopen, better wait until feof finish to read the \r\n separator

<?php
//fsockopen, fputs..

$content = "";
$header = "not yet";

while( !feof( $pointer ) ) {
    $line = fgets( $pointer, 128 );
    if( $line == "\r\n" && $header == "not yet" ) {
        $header = "passed";
    }
    if( $header == "passed" ) {
        $content .= $line;
    }
}

//fclose..

echo( substr( $content, 2 ) );
?>

[NOTE BY danbrown AT php DOT net: Updated version.  Contains author-submitted bug fixes.]

Here is a way to get an array of cities / states for any zip code anywhere in the US.  This example uses a $_GET variable to specify which zip code, but you can get it from any source you wish.  This will return actual and acceptable zip code cities (according to USPS), but can be easily modified to include just the actual city.

<?php

if($_GET['zip'])
{
    if(!($fp = fsockopen('zip4.usps.com', 80, $errno, $errstr)))
        echo 'Could not connect to USPS! Error number: ' . $errno . '(' . $errstr . ')';

    else
    {
        $poststring =

            "GET /zip4/zcl_3_results.jsp?zip5=" . $_GET['zip'] . " HTTP/1.0\r\n" .
            "Connection: close\r\n\r\n";

        fputs($fp, $poststring);

        $buffer = '';

        while(!feof($fp))
            $buffer .= fgets($fp, 128);

        fclose($fp);

        preg_match('/Actual City name(.*)/s', $buffer, $match);

        $temp = explode('Not Acceptable', $match[1]);

        // Capture city/state combination for all valid cities

        preg_match_all('/headers="pre">(?:<b>)?([\w|\s]+), (\w+)/', $temp[0], $acceptable, PREG_SET_ORDER);

        $values = array();

        foreach($acceptable as $value)

            $values[] =

                array
                (
                    'city' => $value[1],
                    'state' => $value[2]
                );

        if(count($values) == 0)
            echo 'Zip could not be found in the database!';
    }
}
else
    echo 'Please specify a zip!';

For those wanting to use fsockopen() to connect to a local UNIX socket who can't find documentation on how to do it, here's a (rough) example:

<?php

$sock = fsockopen('unix:///full/path/to/my/socket.sock', NULL, $errno, $errstr);

fwrite($sock, 'SOME COMMAND'."\r\n");

echo fread($sock, 4096)."\n";

fclose($sock);

When you're connecting through a proxy server you can't rely on fsockopen returning false to indicate that the connection has failed. (This also applies to fgets and fwrite.)

To check whether the proxy succeeded in contacting the real target host, you need to look for the http response code in the headers that get returned. Typically, if the proxy was unable to reach the host, you'll find a line containing something like:
HTTP/1.0 503 Service Unavailable

"system level connect()" is not further documented inside the php documentation so it is hard to find out more about error numbers.

someone suggest a more system-close way to find out more about error numbers here: http://www.askapache.com/php/fsockopen-socket.html (an interesting read about fsockopen anyway).

in my case i could debug to the fact that fsocketopen error number 16 was resulted in the inpossibility to resolve a hostname.

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. :-)

If you have to use a proxy to make requests outside of your local network, you may use this class:

<?php

    public function get_proxy_port() {
        return $this->proxy_port;

    public function set_proxy_port($p) {
        $this->proxy_port = $p;
    }

    public function get_request_url() {
        return $this->request_url;
    }

    public function set_request_url($u) {

            $this->logger("FAILED: get_url(" . $url . ")", "RemoteFopenViaProxyClass.log");
        }

?>

Use it this way:

<?php
// call constructor
$obj = new RemoteFopenViaProxy($insert_request_url, $insert_proxy_name, $insert_proxy_port);
// change settings after object generation
$obj->set_proxy_name($insert_proxy_name);
$obj->set_proxy_port($insert_proxy_port);
$obj->set_request_url($insert_request_url);
$obj->request_via_proxy();
echo $obj->get_result();
?>

If there are errors during execution, the script tries to write some useful information into a log file.

For those of you who do not have cURL, you might want to try this.
It doesn't have all the functions that cURL has, but it has the basics.
Please let me know of any bugs or problems.
