How to cut an image using php?

How can I cut a picture, for example, into 16 identical squares in the form of a 4×4 table? And is it even possible?

Answer 1, authority 100%

To work with the image, you will need the installed GD library. You can check if the library is installed using the code:

echo "<pre>";
echo "</pre>";

You can read more about the capabilities of the GD library here: working with images and the GD library.

You can also use the ImageMagickpackage if the host and server resources allow. The image slicing functions noticeably load the processor and memory resources, so I do not recommend using them for constant image manipulation. If you need to cut several images, it is better to use graphic editors.

The GD2 library and imagecopyresized.
