Re: how do i check if a server is online ?

mysql_connect does not have a timeout option :( I wonder if your timeout is not because of mysql_connect but more a dns problem, try putting the IP in, see if it times out at a more reasonable speed. if not try fsockopen http://php.net/manual/en/function.fsockopen.php open the port, if no errors, close the port and continue, if there are errors then you know the server is down. fsockopen allows for a timeout option, set it to 2 sec or something, should be ok. <?php if ( !($fp = fsockopen ('mysql.server.com', 3306, $errno, $errstr, 2)) ) { echo " There has been an error : $errstr ($error) <br> "; } else mysql_connect('mysql.server.com', 'mysql_user', 'mysql_passwd'); ?> is this server prone to alot of ups and downs ? might want to stay away from mysql_pconnect(). -- Chris Lee Mediawaveonline.com ph. 250.377.1095 ph. 250.376.2690 fx. 250.554.1120 lee@mediawaveonline.com ""Markus H.
