Ist das Skript zur sicheren Bildverarbeitung in PHP geeignet?

To ensure secure image processing in PHP, it is important to validate and sanitize user input to prevent vulnerabilities such as code injection or file upload attacks. One way to achieve this is by using the `imagecreatefromstring` function to handle image data safely. 

// Validate and sanitize user input
$image_data = $_POST['image_data']; // Assuming image data is submitted via POST request
$image_data = base64_decode(preg_replace('#^data:image/\w+;base64,#i', '', $image_data));

// Create image resource from validated data
$image = imagecreatefromstring($image_data);

// Further processing of the image can be done securely
