Quick Question

[ThePsion5]

Hi,Say I create two global variables, one of which contains the other like so:

$var = "your name";$var2 = "My god, $var is teh best PHP coder evuh!!!!!11111";

and I call $var2 inside of a function like so:

function tellTheWorld() {global $var2echo $var2; }

or

function tellTheWorld() {$var = "someone other than you";global $var2echo $var2; }

what exactly will be echoed? In technical terms, if I access a global variable that references another variable, does it reference it in the scope of the function or at the global level?

You raise a good question. I am not 100% sure how PHP does it but in JavaScript if you declare a global variable and then change the value within a function the new value now becomes the global value so anytime the global variable is called (in or outside of a function) the value is whatever the last process set it to not necessarily the original value.Hope that helps...give it a test and see if PHP works the same way...I suspect that it does.
