Surprisingly, on my Linux system, when connected to a localhost service using IPV4, stream_get_socket_name returns ::1 as the peer or local address. One would expect to get localhost or 127.0.0.1 but the ::1 IPV6 localhost is returned instead.
(PHP 5, PHP 7)
stream_socket_get_name — 获取本地或者远程的套接字名称
$handle
, bool $want_peer
) : string返回给定的本地或者远程套接字连接的名称。
handle需要获取其名称的套接字连接。
want_peer
如果设置为 TRUE ，那么将返回 remote 套接字连接名称；如果设置为 FALSE 则返回 local 套接字连接名称。
