Forums Scripts & Popups \b

i'm still not understand what does the \b in regex

Word boundary, read the Perl regex manual page.

your explanation is even shorter then the explanation for that in mircscripts. so i'm too dumb to understand it. any1 can help
me ??

As I said, read the perl manual:

A word boundary (\b) is a spot between two characters that has a \w on one side of it and a \W on the other side of it (in either order), counting the imaginary characters off the beginning and end of the string as matching a \W.
