What is the significance of the "SAFE MODE Restriction" error message in PHP file uploads?

The "SAFE MODE Restriction" error message in PHP file uploads indicates that the server's safe mode settings are preventing the file from being uploaded. To solve this issue, you can disable safe mode in the server's php.ini file or use alternative methods for file uploads that are not restricted by safe mode.

// Disable safe mode in php.ini file
safe_mode = Off;
