WOW Coooooool :-)
but there is one thing i wonder about:
php -r '$ar=array(1=>"a",2=>"b",3=>"c");foreach($ar as $k=>&$v) if ($k==2) unset($v);
print_r($ar);'
Array
(
[1] => a
[2] => b
[3] => c
)
I guess the main question is what should happen? I'd expect the result to be
$ar[2] = NULL since obviously you can't unset $ar[2] this way. (I tried this
because in SPL you can).
