New Comment:
I'm onboard with loop { } else { } construct, but this is an overkill.
I'd much rather have 2 additional array functions: is_array_last(array $array)
and is_array_first(array $array)... Of course, I don't insist on these function
names, but they should basically return true or false when array pointer is at
the first position, or at the last position.

Description:
------------
There are a lot of situations that we want our foreach loop act different for
first and/or last item. It will be so easy if php add these to concepts as
blocks next to foreach. Compiler will run 'first' block for first item, and
'last' block for last item, and normal 'foreach' block for anything in between.
The only special case is when array has only one item, in this situation only
'first' block will act. See example at test script.
Test script:
---------------
foreach($array as $key => $value)
{
$str .= $key . ' = "'.$value.'",';
}
first
{
$str .= '(' . $key . ' = "'.$value.'",';
}
last
{
$str .= $key . ' = "'.$value.'")';
}
