What are some best practices for organizing and testing PHP code that involves image manipulation?

When organizing and testing PHP code that involves image manipulation, it is important to separate concerns by creating separate functions or classes for different tasks such as image loading, manipulation, and saving. Additionally, writing unit tests for each function or method can help ensure that the code works as expected and catches any potential bugs early on. Finally, using a version control system like Git can help track changes and revert to previous versions if needed. 

// Example code snippet for organizing and testing PHP code for image manipulation

// imageUtils.php
class ImageUtils {
    public function loadImage($filename) {
        // code to load image
    }

    public function resizeImage($image, $width, $height) {
        // code to resize image
    }

    public function saveImage($image, $filename) {
        // code to save image
    }
}

// imageUtilsTest.php
require 'imageUtils.php';

class ImageUtilsTest extends PHPUnit_Framework_TestCase {
    public function testLoadImage() {
        $imageUtils = new ImageUtils();
        $image = $imageUtils->loadImage('test.jpg');
        $this->assertNotNull($image);
    }

    public function testResizeImage() {
        $imageUtils = new ImageUtils();
        $image = $imageUtils->loadImage('test.jpg');
        $resizedImage = $imageUtils->resizeImage($image, 100, 100);
        $this->assertNotNull($resizedImage);
    }

    public function testSaveImage() {
        $imageUtils = new ImageUtils();
        $image = $imageUtils->loadImage('test.jpg');
        $filename = 'resized_test.jpg';
        $saved = $imageUtils->saveImage($image, $filename);
        $this->assertTrue($saved);
    }
}
