note 72674 added to function.fsockopen

Sorry for multiple submission of this but Added @ to suppress errors and a few exmples: Also note that this script checks specific ports so you need to have the correct port open on the server for this to work. E.g if i have a windows domain controller and it is servering LDAP then the following would be used to check it is online: chkServer("MyDC", "389"); for a webserver chkServer("MyWebSvr", "80"); etc etc -------------------------------------------------------- // check if a server is up by connecting to a port function chkServer($host, $port) { $hostip = @gethostbyname($host); // resloves IP from Hostname returns hostname on failure if ($hostip == $host) // if the IP is not resloved { echo "Server is down or does not exist"; } else { if (!$x = @fsockopen($hostip, $port, $errno, $errstr, 5)) // attempt to connect { echo "Server is down"; } else { echo "Server is up"; if ($x) { @fclose($x); //close connection (i dont know if this is needed or not). } } } } ---- Server IP: 83.138.144.80 Probable Submitter: 212.44.43.189 ---- Manual Page -- http://www.php.net/manual/en/function.fsockopen.php Edit -- https://master.php.net/note/edit/72674 Del: integrated -- https://master.php.net/note/delete/72674/integrated Del: useless -- https://master.php.net/note/delete/72674/useless Del: bad code -- https://master.php.net/note/delete/72674/bad+code Del: spam -- https://master.php.net/note/delete/72674/spam Del: non-english -- https://master.php.net/note/delete/72674/non-english Del: in docs -- https://master.php.net/note/delete/72674/in+docs Del: other reasons-- https://master.php.net/note/delete/72674 Reject -- https://master.php.net/note/reject/72674 Search -- https://master.php.net/manage/user-notes.php
