When working with image manipulation functions in PHP, such as imageDestroy(), what are the key considerations for memory management and resource cleanup to prevent issues like memory leaks?

When working with image manipulation functions in PHP, it's important to properly manage memory and resources to prevent issues like memory leaks. One key consideration is to always clean up resources after you're done using them, especially when dealing with image resources. This can be done by using functions like imageDestroy() to free up memory and prevent resource leaks.

// Example of using imageDestroy() to properly clean up image resources
$image = imagecreatefromjpeg('example.jpg');

// Manipulate the image

// Clean up resources
imageDestroy($image);
