socket_bind
(PHP 4 >= 4.1.0, PHP 5) socket_bind -- Binds a name to a socket Descriptionbool socket_bind ( resource socket, string address [, int port] )
Binds the name given in address to the socket
described by socket.
Parameters
- socket
A valid socket resource created with socket_create().
- address
If the socket is of the AF_INET family, the
address is an IP in dotted-quad notation
(e.g. 127.0.0.1).
If the socket is of the AF_UNIX family, the
address is the path of a
Unix-domain socket (e.g. /tmp/my.sock).
- port (Optional)
The port parameter is only used when
connecting to an AF_INET socket, and
designates the port on the remote host to which a connection
should be made.
Return ValuesReturns TRUE on success or FALSE on failure.
The error code can be retrieved with socket_last_error().
This code may be passed to socket_strerror() to get a
textual explanation of the error.
Examples
Example 1. Using socket_bind() to set the source address
<?php
// Create a new socket
$sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
// An example list of IP addresses owned by the computer
$sourceips['kevin'] = '127.0.0.1';
$sourceips['madcoder'] = '127.0.0.2';
// Bind the source address
socket_bind($sock, $sourceips['madcoder']);
// Connect to destination address
socket_connect($sock, '127.0.0.1', 80);
// Write
$request = 'GET / HTTP/1.1' . "\r\n" .
'Host: example.com' . "\r\n\r\n";
socket_write($sock, $request);
// Close
socket_close($sock);
?>

NotesNote:
Windows 9x/ME compatibility note:
socket_last_error() may return an invalid error code
if trying to bind the socket to a wrong address that does not belong to
your machine.
