Answer 1

Gmagick example on how to create a GIF picture from two PNG files:

$first = new Gmagick("example.0.png");
$first->setImageformat("gif");
$first->setImageDelay(100);
$second = new Gmagick ("example.1.png");
$first->nextImage();
$first->addImage($second);
$first->previousImage();
$first->write('example.gif');

Example taken from https://bugs.php.net/bug.php?id=59420

Take care that Gmagick internally keeps track at which image you are, that is why nextImage^­Docs is used before adding the second image and why previousImage^­Docs is used before writing it to disk.

Start with this two picture example and then change it to a version that adds pictures from an array and with three pictures. And then finally read the array from a directory from 0 to N pictures (e.g. with glob). Have fun!
