# socket_getsockname

(PHP 4 >= 4.1.0, PHP 5)

socket_getsockname -- Queries the local side of the given socket which may either result in host/port or in a Unix filesystem path, dependent on its type.

## Description

bool socket_getsockname ( resource socket, string &addr [, int &port])

切記!
這個函數是實驗性質的。這個函數的行為、名稱、和關於此函數的任何其他文件在未來PHP的發行中可能會在不通知的情況下改變。 使用此延伸需自行承擔風險。

If the given socket is of type `AF_INET` or `AF_INET6`, socket_getsockname() will return the local IP address in appropriate notation (e.g. 127.0.0.1 or fe80::1) in the address parameter and, if the optional port parameter is present, also the associated port.

If the given socket is of type `AF_UNIX`, socket_getsockname() will return the Unix filesystem path (e.g. /var/run/daemon.sock) in the address parameter.

> 備注: socket_getsockname() should not be used with `AF_UNIX` sockets created with socket_connect(). Only sockets created with socket_accept() or a primary server socket following a call to socket_bind() will return meaningful values.

成功回傳`TRUE`失敗回傳`FALSE`。 socket_getsockname() may also return `FALSE` if the socket type is not any of `AF_INET`, `AF_INET6`, or `AF_UNIX`, in which case the last socket error code is not updated.

See also socket_getpeername(), socket_last_error() and socket_strerror().
