(PHP 4 >= 4.1.0, 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.| 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 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.
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.
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.
See also socket_getsockname(), socket_last_error() and socket_strerror().
