Setting a variable that will work in a function

[listenmirndt]

is it possible to set a global variable that will work inside of a function... even if it's not one of the functions parameters?

IE

$globalvariable = test;

function test() {
echo $globalvariable;
}

Yes. Read the PHP manual on variable scope.

That said, you should avoid such global variables.
