$count = 1;
forach ( $array as $elem ) {
++$count;
// if you need to print it here:
echo sprintf( "%03d", $count );

}

You can't expect PHP to take care of your leading zeros - they were
lost the moment you assigned 001 to $count (immediately understood as
1). What's worse, if you tried to do something like $count = 017, the
017 would be understood as octal 17, which means 15 decimal (and
that's something you wouldn't expect). sprintf belongs to a family of
functions that can take care of leading zeros by special characters
like "%03d" for "decimal with 3 leading zeros", or "%.2f" for "float
with 2 decimal numbers", etc.
