$GLOBALS holds all variables defined in main(), main() meaning outside 
any function or class

//main()
$my_var = 'test';

function myFunction()
{
    echo $GLOBALS['my_var'];

    // is the same as:
    global $my_var
    echo $my_var;

    // 'global' just creates a local reference to the global variable
    // global $my_var; is the same as:
    $my_var =& $GLOBALS['my_var'];
    echo $my_var;
}
