What are the potential performance implications of generating random images in PHP, and how can they be optimized?

Generating random images in PHP can be resource-intensive, especially if done repeatedly or for large images. To optimize performance, you can cache generated images, reuse them when possible, and consider generating images in batches rather than one at a time. 

// Example of optimizing the generation of random images in PHP

// Function to generate a random image and save it to a file
function generateRandomImage($width, $height, $outputFile) {
    // Generate random image code here
    // Save the image to the output file
}

// Check if the image already exists in the cache directory
$cacheDir = 'cache/';
$randomImage = $cacheDir . 'random_image.png';

if (file_exists($randomImage)) {
    // Use the cached image
    echo 'Using cached image';
} else {
    // Generate a new random image
    generateRandomImage(800, 600, $randomImage);
    echo 'Generated new image';
}
