Try this I think it will work.
$count = count($arry);
for ($i=0; $i<$count; $i++) {
// do something with $array[$i]
}
cout($array) brings back the number of elements in the array which limits
the lookup index.

Not sure about a "for" loop inside the "echo".

Yes. Something like this should work:
echo "<beginning html tags>";
foreach ($pieces as $this_piece) {
echo $this_piece . " ";
}
echo "<middle html tags>";
echo $formatted_price;
echo "<closing html tags>";
This should at least give you a starting point. I'm fairly new to php,
so maybe one of the gurus will give a better idea (or explain why mine
won't work, if it won't).

P.S. I would usually trim out the rest of the message, but am leaving
