socket_getpeername

(PHP 4 >= 4.1.0)

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 &addr [, 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 without notice in a future release of PHP. Use this function at your own risk.

If the given socket is of type AF_INET, socket_getpeername() will return the peers (remote) IP address in dotted-quad notation (e.g. 127.0.0.1) 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.

Returns TRUE on success or FALSE on failure. socket_getpeername() may also return FALSE if the socket type is not any of AF_INET or AF_UNIX, in which case the last socket error code is not updated.
