What do you mean? Foreach() can be nested, and it works perfect.

You don't need to reset() the array, You also don
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";
}
}

One apparent problem with foreach() is it can misbehave code as follows.
(4.0.4pl1, 4.0.5RC6)
function foo($a) {
foreach ($a[0] as $k => $v) {
echo $k.$v;
}
}
$a = 'abc';
foo($a);
You'll get 'server not found' or browser waiting forever with this code.
(If you don't, please let me know
What are the differences in these? I know with while() you have to reset() the
array afterwards, but foreach() you don't. Also foreach() appears to be quite
a bit faster.
My main question is there ANY difference in how these two loop through the
array.
