How does the PHP version (PHP 4.0.3pl1) affect the ability to access $_FILES['datei']?

In PHP 4.0.3pl1, accessing the $_FILES['datei'] superglobal array may not work as expected due to potential bugs or limitations in the PHP version. To solve this issue, consider updating to a newer version of PHP that provides better support for handling file uploads. Alternatively, you can try using alternative methods or workarounds to retrieve file upload data if upgrading PHP is not an option.

// Example code snippet to handle file upload in PHP
if ($_SERVER['REQUEST_METHOD'] === 'POST' && isset($_FILES['datei'])) {
    $file = $_FILES['datei'];
    
    // Process the file upload here
    // Example: move_uploaded_file($file['tmp_name'], 'uploads/' . $file['name']);
}
