[PHP] defining vars within functions as global

[Justin French]

Hi,

I'd like to be able to define multiple variables within a function, and have
it available outside the function from the point the function is called...
eg:

<?
function foo()
    {
    $foo = "aaa";
    $bar = "bbb";
    }

foo();

echo $foo;
echo $bar;

?>

How to I specify that $foo and $bar (defined in the func) are to be set
globally (ie, outside the function)?

I'm aware I could return as array of values, but I'm interested to see if
there's another option????


Justin
