I've never done this in PHP but clearly writing your own antialiased line drawing algorithm in PHP will most likely produce something which runs too slowly, so you need to do what you can in external libraries. I would draw the line into a bitmap which was exactly twice the size required and then scale the image back to the correct size when you've done with imagecopyresampled.
