Are there specific tools or techniques that PHP developers can use to monitor and protect their .htaccess files from unauthorized changes or redirects?

To monitor and protect .htaccess files from unauthorized changes or redirects, PHP developers can use file permissions to restrict access to the file, regularly check the file for any unauthorized modifications, and implement secure coding practices to prevent injection attacks. 

<?php
$htaccess_file = '.htaccess';

// Check if .htaccess file exists
if (file_exists($htaccess_file)) {
    // Check file permissions
    if (substr(sprintf('%o', fileperms($htaccess_file)), -4) !== '0644') {
        // Set appropriate file permissions
        chmod($htaccess_file, 0644);
    }

    // Check for unauthorized modifications
    $htaccess_contents = file_get_contents($htaccess_file);
    if (strpos($htaccess_contents, 'UnauthorizedKeyword') !== false) {
        // Handle unauthorized modifications
        // e.g. restore original .htaccess file
    }
}
?>
