note 106006 added to function.socket-create-listen

re vicente dot lopez at caixadesoft dot es's post below The reason only the last port remains bound is because of PHP's automatic garbage collection. $sock is a reference to a resource. When you re-use $sock then the refcount on the resource drops to zero and it is destroyed. This is great because we can write very simple and lazy code, but we also have to be careful to preserve the resources we mean to keep using: foreach($services as $port => $daemon){ if ($sock = @socket_create_listen($port)){ //$sockets[$sock] = $daemon; // using $sock as a key does not preserve it. $sockets[$daemon] = $sock; // saving it as a value does! } else { echo("error\n"); } } ---- Server IP: 69.147.83.197 Probable Submitter: 96.50.58.182 ---- Manual Page -- http://www.php.net/manual/en/function.socket-create-listen.php Edit -- https://master.php.net/note/edit/106006 Del: integrated -- https://master.php.net/note/delete/106006/integrated Del: useless -- https://master.php.net/note/delete/106006/useless Del: bad code -- https://master.php.net/note/delete/106006/bad+code Del: spam -- https://master.php.net/note/delete/106006/spam Del: non-english -- https://master.php.net/note/delete/106006/non-english Del: in docs -- https://master.php.net/note/delete/106006/in+docs Del: other reasons-- https://master.php.net/note/delete/106006 Reject -- https://master.php.net/note/reject/106006 Search -- https://master.php.net/manage/user-notes.php
