No, not really. \b matches the start or end of a word. You can see it
clearly if you do this:
print preg_replace( '/\b/', '-', 'this is a string' ) . "<br>\n";
It will output:
-this- -is- -a- -string-
As it replaces all the word boundaries with a hyphen.
So the regular expression /\bis\b/ will match only the word 'is'
and not 'this' or 'isotope' or 'biscuit'.
