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
bool socket_getsockname
( resource $socket
, string &$addr
[, int &$port
] )
Note:
socket_getsockname should not be used with
AF_UNIX sockets 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_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.
