PHP Get Image size when image is stored as byte array

Question

I have image as binary string. (submitted via POST from C# app as byte array)

I can read it using imagecreatefromstring function. How can I get image size (width and height)?

getimagesize function takes filename as parametar. Is there alternative that can read image from binary string and return image size?
