Re: [PHP-DEV] Don't compare zero exponentials in strings as equal

[Kamil Tekiela]

I actually do a lot of lexicographical comparison with ISO8601 date
strings.
I also have numerical string comparisons, but the truth is I didn't think
they would be cast to integers so that is a potential bug in my code. When
I use < on strings I expect that they will both compare as strings. In
other places, I explicitly cast one or both operands to integers or float.
I do see the problem that many people could use < and > on strings
expecting numerical comparison, but I believe most people expect
lexicographical comparison like me.
