Timeout Function

I would like to see a timeout function implemented in PHP (something like Perl's alarm function would be perfect). I notice there is a set_time_limit() function in PHP, but it cannot be applied to a specified block of code (it applies to the entire script) and it causes a fatal error when the timeout is reached (instead of letting you run some alternate code if the timeout is reached). I would like to solve this by contributing to the PHP source, but I am not much of a programmer. I just know a bit of Perl and am pretty familiar with PHP. I have learned some C++ and I understand that C is similar to Perl. Is the PHP interpreter written in C? Maybe I could contribute. Where can I find details on getting a CVS account for PHP development? I am willing to learn and contribute. -- Jason Sims Senior Editor & System Administrator Inside Mac Games http://www.insidemacgames.com
