Scott,
Because "8" != 8. "8" (and "08") is a string with the numerals representing
the number eight. It is not the number eight. (think back to basic math, the
difference between a number and a numeral)
PHP does some conversions for you automatically but that just saves you from
yourself. (Personally, I wish it wouldn't. People have more trouble
*because* of the automatic conversions than they would if they had to do the
converting themselves.)
To keep from running into this simply do the conversions yourself before you
do comparisons.
intval("08")==8
=C=

I don't see why a string wouldn't work when I use "08" (string) and match it
against the integer 8, or 08.
