Q1.
>You're comparing $a to $b using the regex operator.
Well, it's not all right, but half. Not $a to $b only, but $b to $a also.
In case, I suppose everybody should know use "eq" to compair string...
I just suggest another way, which not costing too much line.
As a CGI comparing habit, input a data twice is mostly in PASSWORD
or E-MAIL, use double "=~" is visually help.
Q2.
> int is not for converting a string to an integer.
Anybody mension that "value" in terms of a "string"? Couldn't it be a real
number? In case, if a string is visually an interger number / real number ,
there is no need to convert, right? $x = "10.5"; print ($x - 10) will
output as 0.5, right?
Unless returning an ASCII sort, I don't think there is any needs to convert
a string to
integer, right?
Please, before critisize, clarify what the question is.
