# socket_connect

(PHP 4 >= 4.1.0, PHP 5)

socket_connect -- Initiates a connection on a socket

## Description

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

Initiates a connection using the socket resource socket, which must be a valid socket resource 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.

成功回傳`TRUE`失敗回傳`FALSE`。 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.

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