(PHP 4 >= 4.1.0)

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.


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


本扩展模块是实验性的。该模块的行为,包括其函数的名称以及其它任何关于此模块的文档可能会在没有通知的情况下随 PHP 以后的发布而改变。我们提醒您在使用本扩展模块的同时自担风险。

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. 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.

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.

如果成功则返回 TRUE,失败则返回 FALSEsocket_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().
