PHP将脚本分散到多个部分以避免服务器超时

Question

I have a script that is very long to execute, so when i run it it hit the max execution time on my webserver and end up timing out.

To illustrate that imagine i have a for loop that make some pretty intensive manipulation one million time. How could i spread this loop execution in several parts so that i don t hit the max execution time of my Webserver?

Many thanks,

If you have an application that is going to loop a known number of times (i.e. you are sure that it's going to finish some time) you can increase time limit inside the loop:

foreach ($data as $row) {
    set_time_limit(10);
    // do your stuff here
}

This solution will protect you from having one run-away iteration, but will let your whole script run undisturbed as long as you need.
