Simple explanation needed for this

[rondog]

I come from an actionscripting background so I am curious as to why this does not work in PHP?

 

<?php
$test = "testvar";

function runMe()
{
echo $test; //--- returns an undefined variable error
}

runMe();
?>

 

How would I go about making $test available to the runMe() method without passing it into the method itself?
