How can the PHP execution time limit be increased for a specific script at runtime?

To increase the PHP execution time limit for a specific script at runtime, you can use the `set_time_limit()` function in PHP. This function sets the maximum execution time for the script in seconds. By calling this function at the beginning of your script, you can increase the time limit for that specific script.

// Set the maximum execution time to 60 seconds
set_time_limit(60);

// Your script code here
