Prevent nginx 504 Gateway timeout using PHP set_time_limit()

Question

I am getting 504 timeouts message from nginx when my PHP script is running longer than usual. set_time_limit(0) does not seem to prevent that! Does it not work

Answer 1

Using set_time_limit(0) is useless when using php-fpm or similar process manager.

Bottomline is not to use set_time_limit when using php-fpm, to increase your execution timeout, check this tutorial.
