Executing the code happens *after* it's been parsed. So, yes, it's a two-stage process, but the stages are parsing and executing. Cheers!

RE: [PHP] Using functions before they're defined
I've found that you can specify a function anywhere in the page and call it
anywhere in the page so:
?
foobar();
function foobar() { echo in foobarbr\n; }
foobar();
?
would work and display the text twice, without errors/warnings
I haven't looked at the php's source code, but maybe it's a two pass parser
(??) first it gets all the functions then it executes the code

Yes, it's all explained in the manual :)
