(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.| Warning |
This function is EXPERIMENTAL. The behaviour of this function, the name of this function, and anything else documented about this function may change in a future release of PHP without notice. Be warned and 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, 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.
