How can you restrict a PHP script to execute for a certain time

In web development, sometimes it’s important to limit the execution time of your PHP scripts to prevent them from running indefinitely. You can achieve this by using the `set_time_limit` function or by modifying the `max_execution_time` directive in your server's PHP configuration. Here’s how you can do it:


        <?php
        // Set the max execution time to 5 seconds
        set_time_limit(5);

        // Example long operation
        $start = time();
        while (true) {
            // Perform your tasks here
            if (time() - $start > 5) {
                echo 'Execution time limit reached. Script will terminate.';
                break;
            }
        }
        ?>
