What are some potential ways to create GIF animations using the GD Lib in PHP?

To create GIF animations using the GD Lib in PHP, you can use the imagegif() function to save multiple frames as individual GIF images and then combine them into an animated GIF. You can achieve this by creating individual frames with different content or by manipulating the same frame to create the animation effect. 

// Create individual frames
$frame1 = imagecreatetruecolor(100, 100);
// Add content to frame1

$frame2 = imagecreatetruecolor(100, 100);
// Add content to frame2

// Save frames as individual GIF images
imagegif($frame1, 'frame1.gif');
imagegif($frame2, 'frame2.gif');

// Create animated GIF
$animation = new Imagick();
$animation->setFormat('gif');
$animation->readImage('frame1.gif');
$animation->readImage('frame2.gif');

// Set animation properties
$animation->setImageDelay(100); // Delay between frames in milliseconds
$animation->setImageDispose(2); // Dispose method for each frame

// Save animated GIF
$animation->writeImages('animation.gif', true);
