Was sind die besten Praktiken für die Verwendung von Scripts zur Bildbearbeitung in PHP?

When using scripts for image editing in PHP, it is important to follow best practices to ensure efficient and secure processing of images. This includes validating user input, sanitizing data, using appropriate image manipulation libraries, and optimizing performance by caching images when possible. 

// Example of using the GD library for image manipulation in PHP
$image = imagecreatefromjpeg('example.jpg');

// Resize the image
$new_width = 100;
$new_height = 100;
$resized_image = imagecreatetruecolor($new_width, $new_height);
imagecopyresampled($resized_image, $image, 0, 0, 0, 0, $new_width, $new_height, imagesx($image), imagesy($image));

// Save the resized image
imagejpeg($resized_image, 'resized_example.jpg');

// Free up memory
imagedestroy($image);
imagedestroy($resized_image);
