PHP will timeout and exit with the following error once it reaches the maximum allowed time for it to execute your scripts;
Fatal error: Maximum execution time of 30 seconds exceeded in yourscript.php
30 seconds is the default timeout, if not specifically configured.
You can avoid this error by increasing the maximum execution time for
PHP. This can be set globally or from within your
PHP scripts via any of these methods:
This approach will affect all the
PHP scripts running in your system. It's the best solution if you're running content management system or framework like
Drupal as you don't need to configure the option manually to all the affected scripts.

PHP configuration file to the number of seconds that want to allow your
PHP scripts to execute.

$ sudo vi /etc/php/7.2/apache2/php.ini
; Maximum execution time of each script, in seconds ; http://php.net/max-execution-time ; Note: This directive is hardcoded to 0 for the CLI SAPI max_execution_time = 30
max_execution_time = 300
Setting it to

It's not recommended to set the value to
0 at this level as this method's system-wide change will cause any misbehaved
PHP scripts to unnecessarily consume precious
$ sudo systemctl restart apache2
This is basically the same as the previous solution, but it's actually a function that you call from your
PHP script. It's a general function to override any configuration options set in your
PHP's configuration file and will only affect the execution of the scripts that call the function.
When placed at the start of your
PHP script, the following function call will allow it to run for 300 seconds (5 minutes).
PHP's built-in function specifically to set the maximum execution time limit of your
PHP scripts. It's to be called from your
PHP script as in the previous method and the following example is to also set the limit to 300 seconds (5 minutes).
set_time_limit ( 300 )
This is the best option if you don't have administrator access to your system but still want to set the option to all your scripts in your project folder.
Add the following lines to
.htaccess file within your
PHP project folder and this will be applied to all the scripts within that folder.
<IfModule mod_php7.c> php_value max_execution_time 300 </IfModule>
mod_php5.c if you're hosting on PHP 5.

The option is readily available in
cPanel's dashboard and can be used to change
PHP's maximum execution time limit.
