Hello I do not know if I'm wrong, but still it is not would be a great tool that greatly simplifies.
Increment and decrement operator or better assignment.
$i++ ;;If he would add one more each time were to have any "++".
Or so.
$i+=1 and $i-=1 ...
If someone is not familiar with that it works so $i=$i+1.
Lets well elegant and faster code.

Now of course is another way to do this?
Thanks in advance and even ...
