Queries the remote side of the given socket which may either result in host/port or in a Unix filesystem path, dependent on its type socket_get_option socket_getsockname Socket Functions PHP Manual socket_getpeername (PHP 4 >= 4.0.7, PHP 5)socket_getpeername — Queries the remote 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_getpeername ( resource $socket , string &$address [, int &$port ] ) Queries the remote side of the given socket which may either result in host/port or in a Unix filesystem path, dependent on its type. Parameters socket A valid socket resource created with socket_create() or socket_accept(). address If the given socket is of type AF_INET or AF_INET6, socket_getpeername() will return the peers (remote) 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_getpeername() will return the Unix filesystem path (e.g. /var/run/daemon.sock) in the address parameter. port If given, this will hold the port associated to address . Return Values Returns TRUE on success or FALSE on failure. socket_getpeername() 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. Notes Note: socket_getpeername() should not be used with AF_UNIX sockets created with socket_accept(). Only sockets created with socket_connect() or a primary server socket following a call to socket_bind() will return meaningful values.
