Question

I have a simple images resizing script that works great for JPEGs, but not for GIFs or PNGs. The first step is getting the correct image type so I can process it accordingly.

My question is: It seems that getimagesize() returns both IMAGETYPE and MIME-type… So which should I use to determine if an imagine is JPEG, PNG, or GIF?

It seems strange that PHP gives you two ways of doing this, so I presume they each have their designated uses?

Answer 1

Documentation says that:

mime is the correspondant MIME type of the image. This information can
be used to deliver images with the correct HTTP Content-type header

I believe IMAGETYPE is valid choice.
