How does safe_mode impact file writing permissions in PHP scripts?

Safe_mode in PHP restricts file writing permissions, making it more secure by preventing scripts from writing to certain directories. To work around this limitation, you can use the `ini_set()` function to temporarily disable safe_mode before performing file writing operations, and then re-enable it afterwards.

// Disable safe_mode temporarily
ini_set('safe_mode', 0);

// Perform file writing operations here

// Re-enable safe_mode
ini_set('safe_mode', 1);
