I have read register globals will not be available in PHP6. Does it mean we'll not be able to use such type of code
PHP Code:
function a()
{
    global 
$b;
    
$b 10;
}

a();
echo 
$b
OR

We'll be unable to receive get/post/cookie/session values using global?

To experiment this, I have disabled register_globals in phpi.ini and run the 1st code. But can easily get the value of $b. Now I am confused by the term register globals.
