PHP: socket_getsockname - Manual

(PHP 4 >= 4.1.0, PHP 5, PHP 7, PHP 8)

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

Parameters

socket

A Socket instance created with socket_create() or socket_accept().

address

If the given socket is of type AF_INET or AF_INET6, socket_getsockname() will return the local 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_getsockname() will return the Unix filesystem path (e.g. /var/run/daemon.sock) in the address parameter.

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.
