You can implement a custom http or https monitor that would perform a GET request, then you could examine the response.
In order to create a custom monitor, you can navigate to Local Traffic >> Monitors, click Create. Enter the name for the monitor and select http/https for the type (depending on what you are planning on using). In the Send String field specify GET /locationOfThePhpScript/filename.php\r\n
In the Receive String enter the string that the file will respond with. It might be easiest if guys implementing the script could respond with i.e. 200 OK or 500 NOK which you would then enter in this field. You could also enter a username and password if they are required. After you are done with setting this up, you can click Finished.
Then navigate to the pool that you wish to monitor using this monitor. And specify the monitor that you have just created as an active monitor in Health Monitors section.
Hope this helps.
