How can the safe mode setting in PHP affect the execution of functions like set_time_limit()?

When PHP is running in safe mode, certain functions like set_time_limit() may be restricted or disabled for security reasons. This can prevent scripts from changing the maximum execution time of a script, which can be problematic for long-running processes. To work around this issue, you can check if safe mode is enabled and use alternative methods to control the script execution time if necessary.

if (ini_get('safe_mode')) {
    // Safe mode is enabled, use alternative method to control script execution time
    // For example, you can use a combination of sleep() and checking elapsed time
} else {
    // Safe mode is not enabled, you can use set_time_limit() as usual
    set_time_limit(60); // Set maximum execution time to 60 seconds
}
