socket_getpeername
(PHP 4 >= 4.0.7, PHP 5)
socket_getpeername — Queries the remote 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_getpeername
( resource $socket
, string &$address
[, int &$port
] )
Parameters
-
socket
-
A valid socket resource created with socket_create()
or socket_accept().
-
address
-
If the given socket is of type AF_INET or
AF_INET6, socket_getpeername()
will return the peers (remote) 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_getpeername() will return the Unix filesystem
path (e.g. /var/run/daemon.sock) in the
address
parameter.
-
port
-
If given, this will hold the port associated to
address
.
Return Values
Returns TRUE on success or FALSE on failure. socket_getpeername() 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.
Notes
Note:
socket_getpeername() should not be used with
AF_UNIX sockets created with socket_accept().
Only sockets created with socket_connect() or a primary
server socket following a call to socket_bind() will return
meaningful values.
