socket_getsockname
(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
说明
socket_getsockname(Socket$socket, string &$address, int &$port = null): bool
注意: 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.
参数
-
socket -
A Socket instance created with socket_create() or socket_accept().
-
address -
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.
返回值
成功时返回 true， 或者在失败时返回 false。 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.

Curiously, getsockname() works for socket_create() and socket_create_pair() Unix-domain (AF_UNIX) sockets if one calls socket_bind() after creation to name the formerly anonymous socket(s).
Using a socket_bind() call also results in a file system "file" (socket, first character 's' in an "ls -l" listing) being created with the given name. Such a "file" will need to be removed explicitly, as closing the socket will not remove it.
