In general, /etc/php/7.0/apache2/php.ini is the file where max_execution_time is configured. After making an update there, you will need to restart Apache with: sudo service apache2 restart

In your case, it sounds like this value is being over-rode in a different file (possibly located in /etc/php/7.0/apache2/conf.d/). The first thing I would try to locate where this is occurring is search the files in /etc with grep For example:

grep -r 'max_execution_time' /etc/

One thing that is important to note is that the command line php command uses a separate configuration file from the one used by Apache. This is generally located at /etc/php/7.0/cli/php.ini but you can find it on your system by running:

php -i |grep "php.ini"

Hello there,

You can create a php info file in order to check the current values and check which is the php.ini file in use. Create the following file in your public_hmtl folder - phpinfo.php and put the following code inside it:

<?php
phpinfo();
?>

You can also use the following command in order to find the location of the php.ini file:

php -i | grep php.ini

The output will be:

Configuration File (php.ini) Path => /etc/php/7.2/cli
Loaded Configuration File => /etc/php/7.2/cli/php.ini

Then check for the current value of max_execution_time you can also check which is the configuration file - php.ini that is currently used and apply the changes there (if the site using the global php.ini file and you change the values for these settings this will make the changes globally for all sites).

You also need to restart your web server in order for the changes to take effect. Additionally, a restart of the php-fpm restart is also needed.

Hope that this helps!
