What are the potential drawbacks of using .htaccess for file security in PHP?

One potential drawback of using .htaccess for file security in PHP is that it may not be portable across different server environments. Additionally, relying solely on .htaccess for security may not provide comprehensive protection against all types of attacks. To address these drawbacks, it is recommended to use a combination of .htaccess rules and PHP code to enhance security measures. 

// Example of combining .htaccess rules with PHP code for file security
// .htaccess rules to deny access to specific files
<FilesMatch "\.(htaccess|htpasswd|ini|phps|fla|psd|log|sh|sql|zip|tar)$">
  Order Allow,Deny
  Deny from all
</FilesMatch>

// PHP code to further restrict access to files
$file = "secure-file.txt";
$allowed_users = array("user1", "user2");

if (!in_array($_SESSION['username'], $allowed_users)) {
  header("HTTP/1.1 403 Forbidden");
  exit;
}

// Code to display the contents of the secure file
echo file_get_contents($file);
