How do I use php code from a different domain?

[danieljames123]

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!)

I think you can do it through Php smarty framework

But some one told me that
" Use AJAX and an echo() command in the PHP to return a value."

Not sure how that would be possible on different domains

[stevemack]

as above mate said, you can use an echo() command that returns a value...!

I am not really sure what you want to do. If the page on the second domain prints out the variable you want, then you can request that page using a function like file_get_contents().
However, you can't execute the PHP code from another domain on your domain. There isn't really a need to use Javascript unless I've mistaken what you're trying to do.
