说明
socket_getsockname
( resource $socket
, string &$addr
[, int &$port
] ) : bool

orfe80::1
) in theaddress
parameter and, if the optionalport
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 theaddress
parameter.port
If provided, this will hold the associated port.
