What is the purpose of hiding the file path in PHP?

Hiding the file path in PHP is important for security reasons, as exposing the file path can potentially make it easier for malicious users to access sensitive files on the server. To hide the file path, you can use PHP's built-in functions like realpath() to get the absolute path of a file without exposing it in the URL.

// Get the absolute path of a file without exposing it in the URL
$filePath = realpath('path/to/file.php');
