How does PHP handle file includes from directories protected by .htaccess?

When a directory is protected by .htaccess, it can prevent PHP from including files located within that directory. To solve this issue, you can use the "auto_prepend_file" directive in your php.ini file to automatically include a file before any PHP script runs. This file can contain the necessary code to include files from the protected directory.

// In your php.ini file
auto_prepend_file = "/path/to/your/include_file.php"
```

```php
// include_file.php
<?php
include '/path/to/protected_directory/file.php';
?>
