I wondered how to create an animated gif image using PHP, but I did not find any information on the Internet about this. Is there any library to work with them?

Yes, I can’t tell you exactly, but there is an article on Habré called captcha 4d. It fully describes how to draw gifs. If I’m not mistaken, the Imagick library is used.
Thanks to Sh4dow for finding the article
