If you want a property that gets the same value in every clone if changed, you can do this simple
trick:
<?php
class A
{
public $name ;
public function __construct()
{
$this->name = & $this->name;
}
}
$a = new A;
$a->name = "George";
$b = clone $a;
$b->name = "Somebody else";
var_dump($a);
var_dump($b);
?>
this will output:
object(A)#1 (1) {
["name"]=>
&string(13) "Somebody else"
}
object(A)#2 (1) {
["name"]=>
&string(13) "Somebody else"
}
You can change any of the clones property and all of the others will change accordingly.
