socket_bind - Binds a name to a socket


bool socket_bind ( resource socket, string address [, int port] )

Binds the name given in address to the socket described by socket. This has to be done before a connection can be established using socket_connect() or socket_listen().

Список параметров


A valid socket resource created with socket_create().


If the socket is of the AF_INET family, the address is an IP in dotted-quad notation (e.g.

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.

Возвращаемые значения

Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки.

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.


Пример 1. Using socket_bind() to set the source address
// 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']    = '';
$sourceips['madcoder'] = '';

// Bind the source address
socket_bind($sock, $sourceips['madcoder']);

// Connect to destination address
socket_connect($sock, '', 80);

// Write
$request = 'GET / HTTP/1.1' . "\r\n" .
           'Host: example.com' . "\r\n\r\n";
socket_write($sock, $request);

// Close


Замечание: This function must be used on the socket before socket_connect().

Замечание: 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.
