I'm not sure what he's up to there, but you only need to declare your variables global if you set them in the global scope (ie, outside a function, or inside a function that declares them global) and you want to use them inside of another function. ie

PHP Code:


			
// included file, echo.tpl
--
echo $var;
--

//your script

$var = "hello world!";
include ('echo.tpl'); // automagically recognizes $var, because the include is treated as though it were part of the parent script

function doesntWork()
{
    echo $var;
}

function works ()
{
    global $var

    echo $var;
}

doesntWork();
works();

If you placed those functions inside the include, they'd work (or not) the same as if they were directly part of the parent script.
