Increase page execution time in php

Question

I am designing an web app which should generate more than 10000 entries at a time. All code works fine but I got an error as server timed out after 2-3 minutes of execution. At the top of the page I mentioned

ini_set('max_execution_time', 0);

as set to 0 = infinity but still page execution stops after 2-3 minutes. Is there any solution for this? Please help.

Thanks in advance.

@DeepKakkar - He is mentioning it in php file which does not requires server restart. — Rikesh, Jun 09 '15 at 06:43
PHP usually times out after 30 seconds if nothing else is specified. So this seems to be a problem with your webserver, not with PHP, since the script runs longer. — Realitätsverlust, Jun 09 '15 at 06:45

There are many places to timeout:

PHP scripts via :
max_execution_time ini setting, already covered
set_time_limit() which is basically the same as above
max_input_time which defaults to infinity so this likely isn't the issue
Client timeouts, which may be different depending on the browser (often default to somewhere between 2 and 5 minutes), or may be modified in JavaScript, on the XMLHttpRequest object for example.
Some sort of middleware specific to your configuration, perhaps a configuration parameter in a reverse proxy like nginx or apache, or some sort of FastCGI setting.

Good luck finding it.

First, you need to check that Is your server run your site in safe mode or not because You can not change this setting with ini_set() when running in safe mode. Many hosts run in safe mode so better to check first.

max_execution_time only limits the script execution time of itself i.e. CPU time of your script.

In case if you do with set_time_limit() then the same restriction is in place on set_time_limit().

set_time_limit() is indeed just a convenience wrapper around the according ini_set() call. You can check difference between them here.

Second, after set time limit then you should also set the memory limit with ini_set('memory_limit','32M'); . memory unit depends upon your requirement.

Using this condition you can check that Is your limit function effects value or not

echo 'Time Limit = ' . ini_get('max_execution_time') .

So better to check result with changes. This way you can check, Is your changes working or not, if not then you need to consult with support
