In a function you can use the "return" to return a variable that the function creates to the general variable pool...
But HOW do you can a variable in the pool inside the function AUTOMATICALL -- without giving any parameters to the function.
For instance
$car = "ugly";
function blah( i CANT have parameters here... )
{
echo $car == OUTPUTS UNDEFINED
};
How can I get the $car variable inside the function without having parameters between the ()'s?
