socket_getsockname
(PHP 4 >= 4.1.0, PHP 5, PHP 7)
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
Description
socket_getsockname ( resource $socket , string &$addr [, int &$port ] ) : bool
Note: socket_getsockname() should not be used with
AF_UNIXsockets 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.
Parameters
-
socket -
A valid socket resource created with socket_create() or socket_accept().
-
addr -
If the given socket is of type
AF_INETorAF_INET6, socket_getsockname() will return the local IP address in appropriate notation (e.g.127.0.0.1orfe80::1) in theaddressparameter and, if the optionalportparameter 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 theaddressparameter. -
port -
If provided, this will hold the associated port.
Return Values
Returns true on success or false on failure. socket_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.
