socket_getpeername

(PHP 4 >= 4.1.0, PHP 5, PHP 7)

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

说明

socket_getpeername ( resource $socket , string &$address [, int &$port ] ) : bool

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.

参数

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.

返回值

成功时返回 TRUE， 或者在失败时返回 FALSE。 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.

注释

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.

Note:

For having socket_getpeername() to return a meaningful value, the socket it is applied upon must of course be one for which the concept of "peer" makes sense.
