I asked this in the windows section yesterday and received no answer. I have copied the sample of gmp_add() from the function page and have tried to run it from the snap that I downloaded this morning with the recommended ini that is in the folder with it and I keep getting the error here. PHP Fatal error: Call to undefined function gmp_add() do I need a dll extension or need to install gmp somehow?
