How can one optimize PHP scripts to prevent issues like script "hanging"?

One way to optimize PHP scripts to prevent issues like script "hanging" is to set a maximum execution time for the script using the `set_time_limit()` function.

// Set maximum execution time to 30 seconds
set_time_limit(30);
