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...
