PHP: JPEG pixel dimensions

In PHP, i have Jpeg files that i'm displaying and i need to know the pixel dimensions.
What built-in function call can i use to return the pixel H & W of the image.
(clarification:  this is not file size)

I've looked thru imagemagick but cannot find anything that does this.

thanks
