It's because most of array actions can be done much more effectively & =
transparant with foreach() loops.
Before that, we had to do something like this:
$array =3D array(1,2,3,4,5,6);
//some code
reset($array);
while($item =3D each($array)){
echo "Key =3D ".$item['key'];
echo "Value =3D ".$item['value'];
}

Normally, I don't use an arrays pointer in PHP. Foreach is quite enough =
=
usually (possibly with an continue statement), and I use references to =
array items if not.
