In the following case you don't have to use = & operator when returning a reference:
<?php
class a {
public $a = 1;
}
class b {
static $var;
public static function & gvar($i) {
if(!(isset(b::$var[$i]))) {
b::$var[$i] = new a;
}
return b::$var[$i];
}
}
$b = new b;
$a = b::gvar(1);
$a->a = 14;
$c = b::gvar(1);
echo $c->a; // 14
?>
Note the $a = b::gvar(1) instead of $a = & b::gvar(1)!!!
