Not entirely true. Try:
$string = "0.0";
print $string;
- prints "0.0"
Now try it without the quotes around 0.0
- prints "0"
So there is a difference between strings and numbers. In the $counter case
it doesn't make any difference, but for the above case it could be important
- "0.0" is true in a boolean evaluation, while 0 is false, for example. I
will admit I have no idea how often it is important though.
Incidentally, autoincrement also works for strings anyway, try:
$a = "a"; $a++; print $a;
so your example would work whether $a is being treated as a string or a
number
