What are the potential pitfalls of using htaccess to protect directories in PHP applications?

One potential pitfall of using htaccess to protect directories in PHP applications is that it can be bypassed if the PHP code within the protected directory is vulnerable to attacks like directory traversal. To solve this issue, it's important to also implement proper input validation and sanitization in your PHP code to prevent such vulnerabilities. 

// Example of input validation and sanitization in PHP code to prevent directory traversal attacks
$directory = $_GET['directory'];

// Validate and sanitize the input
$directory = filter_var($directory, FILTER_SANITIZE_STRING);

// Check if the directory is within the allowed paths
$allowed_paths = ['path1', 'path2'];
if (!in_array($directory, $allowed_paths)) {
    // Handle error or redirect to a safe location
    header('Location: /error.php');
    exit;
}

// Proceed with accessing the directory
// Your code logic here
