# socket_connect

(PHP 4 >= 4.1.0)

socket_connect -- Initiates a connection on a socket

## Description

``int socket_connect` (resource socket, string address [, int port])`

Warning
This function is EXPERIMENTAL. The behaviour of this function, the name of this function, and anything else documented about this function may change in a future release of PHP without notice. Be warned and use this function at your own risk.

Initiates a connection using the socket descriptor `socket`, which must be a valid socket descriptor created with socket_create().

The `address` parameter is either an IP address in dotted-quad notation (e.g. `127.0.0.1`), if the socket is of the `AF_INET` family; or the pathname of a Unix-domain socket, if the socket family is `AF_UNIX`.

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.

Returns zero on success, or a negative error code on failure. This code may be passed to socket_strerror() to get a textual explanation of the error.

See also socket_bind(), socket_listen(), socket_create(), socket_get_status(), and socket_strerror().
