In PHP image manipulation, how do I parallelize workloads?

In this example, we will discuss techniques for parallelizing workloads in PHP when performing image manipulation. Utilizing parallel processing can significantly improve performance and efficiency, especially when dealing with large batches of images.

<?php $images = ['image1.jpg', 'image2.jpg', 'image3.jpg', 'image4.jpg']; // Function to process image function processImage($image) { // Simulate image processing sleep(2); // Simulate time-consuming process echo "Processed: " . $image . "<br>"; } // Use parallel processing with pthreads (requires pthreads extension) class ImageProcessor extends Thread { private $image; public function __construct($image) { $this->image = $image; } public function run() { processImage($this->image); } } $threads = []; foreach ($images as $image) { $thread = new ImageProcessor($image); $thread->start(); $threads[] = $thread; } // Wait for all threads to finish foreach ($threads as $thread) { $thread->join(); } ?>
