Call a function before the page is timeout in PHP

问题

I have a PHP script that will run for a long time. I have set the execution time limit to 5 minutes by using set_time_limit() function. I would like to ask whether I can set the script to call a function when timeout limit is reached? like the page unload script in JavaScript or viewDidUnload function in NSViewController, in iPhone SDK ?

回答1:

You can use register_shutdown_function() to register a callback, that is called, when the execution finishes. You should also have a look at connection handling.

回答2:

You can do it by using register_shutdown_function() But this isn't good practice, remeber that you will catch also fatal error, parse errors etc.
