Hi! What is posted in the manual does not work as expected:
class DTO
{
public $msgs = "ergegefr";
public $a = 1;
public $b = 2;
function Insert(){
global $msgsb, $a, $b;
$b = $a + $b;
print $msgs; //Prints nothing
print $b; //Prints 0
}
}

This is explained in the Manual. Please ask support question to
php-general.
Note: Reference is not a pointer. This is confiuing, but it will not be
fixed.

<?
$a = 1;
$b = 2;
function Sum() {
global $a, $b;
$b = &$a;
}
echo "a=$a b=$b";
?>
I expect echo to output "a=1 b=1" since within Sum I set the variable $b
(which refers to global $b) as a reference to $a.
However, this works using $GLOBALS instead of the keyword global.
