How to exceed max_execution_time in PHP

In PHP, I want to run a script who need 2 minutes to compute but my max_execution_time is only 30 seconds.
I can't change my max_execution_time in php.ini nor call shell_exec

I already done all the optimization I could think of. Any idea?

You can also set it in your .htaccess file

Add the following line to your .htaccess file

php_value max_execution_time 200

The "best" option you have is to cut your algorithm into smaller part. Each part should execute within 30 second to avoid timeout. Here are few ideas.

Using CURL:

  • [Script Start] Call run.php let is compute for 20s.
  • Save it stat into a database with an ID
  • Make a CURL call run.php?resumeID=384 [Script finish]
  • [Script Start] retrieve the stat and continue the computation
  • and so on...

Using CRON task:

  • call run.php every second. It will pick a task in your database then flag as "in progress". So next time run.php is call it will not pick the "in progress task"
  • After 20s of computation, save the stat of your script in database and change the "in progress" flag to false.
  • Next call to run.php will pick the task and continue the processing
  • and so on...

Use like

ini_set('max_execution_time', 100);

Even if you can't change the php.ini file itself, you might be able to change options via PHP code with ini_set.

You can also try to call set_time_limit inside your code, resetting the current time counter (this doesn't work in safe mode).

If that doesn't work, try to split the task up into multiple sub-tasks and save the temporary results, so that you can perform the task on multiple executions and thus bypass the time limit.
