I believe foreach also works on a copy basis, not a pointer or reference. So
if you try and alter the array you are foreach'ing it won't work as
expected.
For instance this:
$array = array("var1", "var2", "var3");
foreach ($array as $val)
{
if ($val == "var2")
{
$val = "changed2";
}
}
print_r($array);
Will show you that no change to $array has occurred.
It's basically the same as list(), but it's worth noting.
Other than backwards compliance, I've never used the list/each way of doing
it. Never really had a reason too...I think it basically just comes down to
user preference.
