What are some tips for optimizing image processing functions in PHP for better performance?

To optimize image processing functions in PHP for better performance, consider using a caching mechanism to store processed images and avoid repetitive processing. Additionally, try to reduce the size of images before processing them to improve processing speed. Using libraries like GD or Imagick can also help in optimizing image processing functions. 

// Example of caching processed images to improve performance
function processImage($imagePath) {
    $cachePath = 'cache/' . basename($imagePath);
    
    if (file_exists($cachePath)) {
        return $cachePath;
    }
    
    // Process image here
    
    // Save processed image to cache
    copy($processedImagePath, $cachePath);
    
    return $cachePath;
}
