In case of error it will not only alert problem but it will send useful info as well (http code, respond and error decription). fsockopen is a low level function and you will need a little more PHP code to achieve functionality of <strong>curl</strong> (in case of testing http servers). Anyway, if you only need to test if some port is dead or alive, <strong>fsockopen</strong> will be just fine. Any other comment is more then welcome. @Salman - This script is primarily created for testing http servers.

I tried using fsockopen for checking port 22 and 25. Can anyone please tell me what would be the benefit of using curl or should I only use fsockopen for all ports.

If you have installed PERL, then the <a href="http://mon.wiki.kernel.org/index.php/Main_Page" title="Service Monitoring Daemon" rel="nofollow">mon</a> (Service Monitoring Daemon) will be excellent choice. I used it for LDAP and it works just fine. Please see the huge <a href="http://mon.wiki.kernel.org/index.php/Monitors" title="mon - services list" rel="nofollow">list</a> of services that can be monitored with mon package.

Any idea how one could monitor other ports other than 80? I have been having trouble with dns on one machine. I have filed a support ticket but in the meantime I would like to get it fixed. Monitoring of email smtp service and dns would be great. It would somehow just have to open a connection rather than follow all the way through. Thank you KM Thanks for the script.

Yes, it's annoying but it does the job. On the other hand if you want to suppress repeated messages, then PHP code will grow and this will no longer be a simple PHP monitor ... Anyway, thank you for the comment. :) I have this monitor script in production and if a Web site is down for an hour, then I will receive about 12 mail notifications (cron runs it every 5 minutes).

I did not want something complicated and this does exactly what it has to do. A nice addition of the script might be that repeat messages are suppressed. But then again, that’s only needed if you’re website is down for a long time ;-) Thanks, just what I needed!
