Code that never exits?

[simonc]

I'm getting incoming emails to activate a PHP script, not web page
requests - so I can't visibly see things with a browser.

Is there any way I can detect if one of my PHP scripts never exits - either
the script "crashes" or enters an infinite loop?

Is there some sort of timeout value a server will place on a script, that it
must complete execution by a certain time, or it gets stopped?

And are there any questions I should be asking of my web hosting service
i.e. "does your server know if a script has gone bad or has run for too
long?"

Thanks in advance,

Simon.

Re: Code that never exits?

I found my answer:

There is a default script execution time set to 30 seconds by php, at which
point the script will stop processing and it will spit out an error.

For more info check out the docs on the php function:

set_time_limit

Simon,

set_error_handl er() might help you too - if your scripts were timeing out,
or abort for some reason or other, you can 'trap' the failure with your own
custom made function (thus have it report elsewhere or write something to a
log file or dump variables to a file helping you to debug things). Check
the online PHP Manual under "Error Handling and Logging Functions"... there
might be more tools to help you out there...

Another thing you can do is just make the script write to a logfile
when the script is called and when the script is ready, and if there
are any entries without the second log message then you know that the
script didn't complete.
