RGB or CYMK image in PHP

In my PHP application, I want to allow only RGB images to be uploaded. Using the getimagesize() function, an array is returned in which one element is channels. Its value is 3 for RGB and 4 for CYMK images.

Now, the problem is for PNG images is that the function returns no channels value. Therefore, how can I check PNG images?

Easy. PNG doesn't support CMYK.
