What is the significance of saving PHP files as UTF-8 without BOM?

Saving PHP files as UTF-8 without BOM is significant because it ensures that the file is encoded in a standard format that is compatible with various systems and editors. The presence of a Byte Order Mark (BOM) at the beginning of the file can cause issues with PHP scripts, leading to unexpected output or errors. By saving PHP files as UTF-8 without BOM, you can prevent these issues and ensure smooth functioning of your scripts.

// Ensure PHP files are saved as UTF-8 without BOM
// Add this line at the beginning of your PHP file
header('Content-Type: text/html; charset=utf-8');
