How do I use php code from a different domain?

Here's what I'm trying to do: I have a php page I created on one domain, that stores information in a database. Next, I have another web page (This page is html NOT php) on a Different domain that I call this php page using Javascript, and would like to return a variable from the php page. How is this possible? I know it is, so don't say that it isn't! (10 points for the person that finally answers this question!)

Best Answer:

Ok, this makes marginally more sense. So, you want your PHP to return a variable to the JavaScript? Try a hidden field: <input id="myHiddenField" value="myValue" type="hidden" hidden/> and the js: var value = document.getElementById('myHiddenField').value; if that is not the case, if you are trying to get a JS variable into PHP, that cannot be done. PHP is a server side language, which means the code is DONE by the time the web page is displayed. JavaScript is a client side language, which means the code is executed ONCE THE PAGE IS LOADED. Communication between client-side and server-side languages is limited, and one way (server-side->client-side via hidden field [crude]). I suggest you rethink your method...
