Re: Reg Expression Question

you could do something like that:

$okvalues = "0 20 34 23 5";

for($i = 1; $i < 100; $i++) {
    if($okvalues =~ m/$i/) {
        print "$i\n";
    }
}

Did you try the code you suggested above? For output I get:

2
3
4
5
20
23
34

It incorrectly matches on 2,3 and 4. Now if you had modified your regex to be:

$okvalues =~ m/\b$i\b/

You wouldn't have that problem, because the \b assertion is only true between a word char and a non wordchar. This stops '3' from matching on '34'. Though, its still not a good idea to do it this way.
