How does the Safe Mode setting in PHP affect the functionality of a web server?

Safe Mode in PHP is a security feature that restricts certain potentially dangerous functions, such as accessing files outside the document root or executing shell commands. While it can improve security, it may also limit the functionality of some scripts, especially those that require access to system resources. To address this issue, you can disable Safe Mode in PHP by editing the php.ini file or using the ini_set() function in your script.

// Disable Safe Mode in PHP
ini_set('safe_mode', 0);
