In PHP image manipulation, how do I use caching?

This guide explains how to implement caching for image manipulation in PHP using JavaScript. Caching can significantly improve performance and reduce server load.

<?php // Define a function to handle image caching function cacheImage($imagePath) { $cacheFile = 'cache/' . md5($imagePath) . '.png'; // Check if the cached file exists if (file_exists($cacheFile)) { // Return the cached image return $cacheFile; } // Load the original image $image = imagecreatefrompng($imagePath); // Perform image manipulation (example: resize the image) $resizedImage = imagescale($image, 100, 100); // Resize to 100x100 // Save the resized image to the cache imagepng($resizedImage, $cacheFile); // Free up memory imagedestroy($image); imagedestroy($resizedImage); // Return the path of the cached image return $cacheFile; } // Example usage $imagePath = 'path/to/your/image.png'; $cachedImage = cacheImage($imagePath); echo "<img src='$cachedImage' alt='Cached Image'>"; ?>
