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(Socket $socket
, string &$address
, int &$port
= null
)
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 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.
