Hi all,
I want to write regular expression for checking the string format entered by
user.
the allowed formats are
examples:
10
10,
10,12-10
12-10
that is the valid strings are:
1. only integer
2. an integer, range of integers example 3
and no other characters must be allowed.
ereg("^[-0-9,]+$"...
would do it, but it would also allow "10,-" as a valid expression as
well.. so if you want to check for valid ranges you'll want to beef that
up a bit...
