What are the limitations of the set_time_limit function in PHP, particularly when PHP is running in Safe Mode?

When PHP is running in Safe Mode, the set_time_limit function may not work as expected due to restrictions imposed by Safe Mode. In Safe Mode, the set_time_limit function may be disabled or limited, preventing you from changing the maximum execution time of a script. To work around this limitation, you can use the max_execution_time directive in the php.ini file to set the maximum execution time globally for all scripts.

// To set the maximum execution time globally in php.ini file
// Open php.ini file and add or modify the following line
// max_execution_time = 30 // 30 seconds as an example
