Possible to parse PDF file in PHP?

Hi

I want to know if it is possible to view a PDF file in a webapp of some kind, then be able to draw over lines in the PDF file and submit the lengths to an MySQL database.

Basically import a PDF file, trace around a shape in that PDF file and save those values.

Is it possible? and can someone point me in the right direction on where to read more.

Thanks

 

I think it will help you. So try it.

If someone can do this, I will pay you to write me a PHP example.
PM me if you think you can do it.
