Subject: Re: [PHP-DEV] Make set_time_limit() timeout a catchable fatal error
From: landeholm@gmail.com (Hannes Landeholm)

I second making time limit reached catchable. All non catchable fatal errors
are a problem for me. I need to handle problems gracefully to ensure the
stability of production systems instead of PHP just killing itself without
warning. I just reported a similar issue:
http://bugs.php.net/bug.php?id=54195

A simple way to implement this would be to register a function that would be
called N seconds before the script would timeout.

register_timeout_handler(2, function() { die("PHP timed out."); });

It would be called just as a shutdown function - in fact I'd like to use the
same function as my shutdown function and get the error with
error_get_last(). Of course set_time_limit(0) could be used in this function
to prevent the timeout of the timeout handler. This does not "prevent"
timeout since set_time_limit could have been called by the script before the
timeout anyway.

On that note I also miss a function which returns the time the script can
keep running for. If that calculate needs to be calculated to implemented to
implement this, why not make the value available to the PHP script?
