[PHP-DEV] References

[LingWitt]

The current support for references is mediocre at best. For instance:

class foobar
{
        var $variable;
        
        function foobar()
        {
                $variable = "foobar";
        }
}
//This form of new assignment should be the default
$a = & new foobar();
$b = & new foobar();
$b->variable = "Hello";
$array = array(&$a, &$b);

//The foreach construct uses copies instead of references.
foreach ($array as $element)
        $element->variable = "Hi";
echo $a->variable; //echoes "foobar"
echo $b->variable; //echoes "Hello";
//In order for the above to work, a loop is required.
for ($i = 0, $count = count($array); $i < $count; $i++)
{
        $element = &$array[$i]; //shown explicitly.
        $element->variable = "Hi";
}
echo $a->variable; //echoes "Hi"
echo $b->variable; //echoes "Hi";
//Variable args are always copies,
Function foo()
{
        $args = func_get_args()
        
        //even loop doesn't work:
        for ($i = 0, $count = count($args); $i < $count; $i++)
        {
                $element = &$args[$i];
                $element->variable = "Hello";
        }
}
foo(&$a, &$b);
echo $a->variable; //echoes "Hi"
echo $b->variable; //echoes "Hi";
Thanks for your time,
