Are there any specific configurations in Apache on Ubuntu that can affect the PHP execution time limit?

Yes, the PHP execution time limit can be configured in the Apache configuration file on Ubuntu. The `php_admin_value max_execution_time` directive can be set in the virtual host configuration file to specify the maximum time (in seconds) a PHP script is allowed to run. This can help prevent long-running scripts from consuming excessive server resources.

<Directory /var/www/html>
    php_admin_value max_execution_time 60
</Directory>
