php - Is it possible to access variables without putting "global" in front of them in functions? -

my code much more complex this, here's of it:

$string = "wuddup"; function echothis() { echo $string; } echothis();

is there easy way without saying global $string?

reason being, have check login function, many variables , have config variables outside function...

whatever happened parameters?

function echothis($str) { echo $str; } echothis($string);

if having issues managing variables , scope, chances need refactor code structure.
