note 94749 added to function.stream-socket-server

In some specialized scenarios, you may want to create an AF_INET socket (UDP or TCP) but let the system select an unused port for you. This is a standard feature of internet sockets but it doesn't seem to be documented how to do this for the stream_socket_server function. It appears you can get this behavior by selecting zero for the port number, for example, my test below printed "127.0.0.1:4960". $sock = stream_socket_server("udp://127.0.0.1:0"); $name = stream_socket_get_name($sock); echo $name; ---- Server IP: 208.69.120.35 Probable Submitter: 216.2.7.178 ---- Manual Page -- http://www.php.net/manual/en/function.stream-socket-server.php Edit -- https://master.php.net/note/edit/94749 Del: integrated -- https://master.php.net/note/delete/94749/integrated Del: useless -- https://master.php.net/note/delete/94749/useless Del: bad code -- https://master.php.net/note/delete/94749/bad+code Del: spam -- https://master.php.net/note/delete/94749/spam Del: non-english -- https://master.php.net/note/delete/94749/non-english Del: in docs -- https://master.php.net/note/delete/94749/in+docs Del: other reasons-- https://master.php.net/note/delete/94749 Reject -- https://master.php.net/note/reject/94749 Search -- https://master.php.net/manage/user-notes.php
