How can the risk of exposing PHP code through file() function be mitigated to prevent unauthorized access to scripts?

The risk of exposing PHP code through the file() function can be mitigated by restricting access to sensitive files using appropriate file permissions. By setting the permissions of PHP files to prevent unauthorized access, we can ensure that only authorized users can view the contents of the scripts. 

// Example of restricting access to sensitive PHP files
$file_path = 'sensitive_script.php';

// Set file permissions to prevent unauthorized access
chmod($file_path, 0600);

// Only allow access to the file if the request is coming from an authorized user
if (is_authorized_user()) {
    $file_contents = file_get_contents($file_path);
    // Process the file contents as needed
} else {
    // Handle unauthorized access
    echo "Unauthorized access";
}
