Set ini max_execution_time doesn't work - php

Question

Before I use nginx and php-fpm, I used Apache, so when I wanted only one of my cron jobs to run without time execution limitation, I used these lines in my PHP code:
set_time_limit(0);
ini_set('max_execution_time', 0);
but after I migrated from Apache to nginx, this code doesn't work. I know ways to change nginx.conf to increase maximum execution time.
But I want to handle this with php code. Is there a way?
I want to specify only one file that can run PHP code without time limitation.

Answer 1

Try This:
Increase PHP script execution time with Nginx
You can follow the steps given below to increase the timeout value. PHP default is 30s. :
Changes in php.ini
If you want to change max execution time limit for php scripts from 30 seconds (default) to 300 seconds.
vim /etc/php5/fpm/php.ini
Set…
max_execution_time = 300
In Apache, applications running PHP as a module above would have suffice. But in our case we need to make this change at 2 more places.
Changes in PHP-FPM
This is only needed if you have already un-commented request_terminate_timeout parameter before. It is commented by default, and takes value of max_execution_time found in php.ini
Edit…
vim /etc/php5/fpm/pool.d/www.conf
Set…
request_terminate_timeout = 300
Changes in Nginx Config
To increase the time limit for example.com by
vim /etc/nginx/sites-available/example.com
location ~ \.php$ {
include /etc/nginx/fastcgi_params;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_read_timeout 300;
}
If you want to increase time-limit for all-sites on your server, you can edit main nginx.conf file:
vim /etc/nginx/nginx.conf
Add following in http{..} section
http {
#...
fastcgi_read_timeout 300;
#...
}
Reload PHP-FPM & Nginx
Don’t forget to do this so that changes you have made will come into effect:
service php5-fpm reload
service nginx reload
or try this
fastcgi_send_timeout 50;
fastcgi_read_timeout 50;
fastcgi has it's own set of timeouts and checks to prevent it from stalling out on a locked up process. They would kick in if you for instance set php's execuction time limit to 0 (unlimited) then accidentally created an infinite loop. Or if you were running some other application besides PHP which didn't have any of it's own timeout protections and it failed.

Answer 2

I think that if you have php-fpm and nginx "you can't" set this time only from PHP.
What you could do is a redirect with the parameters indicating you where to continue, but you must control the time that your script is running to avoid timeout.
If your process runs in a browser window, then do it with Javascript the redirect because the browser could limit the number of redirects... or do it with ajax.
Hope that helps.

Answer 3

You can add request_terminate_timeout = 300 to your server's php-fpm pool configuration if you are tried all of solutions here.

Answer 4

ini_set('max_execution_time', 0);
do this if "Safe Mode" is off
set_time_limit(0);
Place this at the top of your PHP script and let your script loose!
Note: if your PHP setup is running in safe mode, you can only change it from the php.ini file.
