Are there any best practices for optimizing image processing in PHP to handle high traffic?

When handling high traffic in PHP for image processing, it is important to optimize the code to reduce server load and improve performance. One way to achieve this is by caching images to minimize the need for repeated processing. Additionally, using efficient image processing libraries such as GD or Imagick can help streamline the process. 

// Example caching function to optimize image processing
function processImage($imagePath) {
    $cachePath = 'cache/' . basename($imagePath);
    
    if (!file_exists($cachePath)) {
        // Process the image and save it to the cache
        $image = imagecreatefromjpeg($imagePath);
        // Perform image processing operations here
        
        // Save the processed image to the cache
        imagejpeg($image, $cachePath);
        imagedestroy($image);
    }
    
    // Return the cached image path
    return $cachePath;
}

// Example usage
$processedImagePath = processImage('image.jpg');
echo '<img src="' . $processedImagePath . '" />';
