note 94350 added to function.socket-connect

This will give you a simple port-checker. Note that on production-machines, you might want to alter the error reporting-level, since unsuccessful connects will give you a "No connection could be made because the target machine actively refused it"-error in the log. Under Windows, make sure you enable the php_sockets.dll extension in your php.ini. <?php $address=$_SERVER['REMOTE_ADDR']; if (isset($_REQUEST['port']) and (!strlen($_REQUEST['port'])==0)) $port=$_REQUEST['port']; else unset($port); if (isset($port) and ($socket=socket_create(AF_INET, SOCK_STREAM, SOL_TCP)) and (socket_connect($socket, $address, $port))) { $text="Connection successful on IP $address, port $port"; socket_close($socket); } else $text="Unable to connect<pre>".socket_strerror(socket_last_error())."</pre>"; echo "<html><head></head><body>". $text. "</body></html>"; ?> Greetz, Peter. ---- Server IP: 69.147.83.197 Probable Submitter: 83.82.6.59 ---- Manual Page -- http://www.php.net/manual/en/function.socket-connect.php Edit -- https://master.php.net/note/edit/94350 Del: integrated -- https://master.php.net/note/delete/94350/integrated Del: useless -- https://master.php.net/note/delete/94350/useless Del: bad code -- https://master.php.net/note/delete/94350/bad+code Del: spam -- https://master.php.net/note/delete/94350/spam Del: non-english -- https://master.php.net/note/delete/94350/non-english Del: in docs -- https://master.php.net/note/delete/94350/in+docs Del: other reasons-- https://master.php.net/note/delete/94350 Reject -- https://master.php.net/note/reject/94350 Search -- https://master.php.net/manage/user-notes.php
