can't acces variables 1

[801119]

Why can't I access any variables from out side of functions??
This code for example will not print anything,.. why?? :s
<?
$txt = &quot;hello world&quot;;
function xPrint()
{
echo $txt;
}
xPrint();
?>

My codes look like something a kid wrote
I have absolutely no idea what I am talking about
Somehow I still manage to make it work

Functions have a different variable scope from the main body of the script. The reference to $txt you use inside the function is a different variable from the one you reference outside the function. They just happen to have the same name.

This page is from the PHP online manual on variable scoping:
