Talk:Group string

(Move from main page)

group(0) matches the entire expression. After that, group(n) matches the expression defined by the nth set of parentheses.--Heeheehee 06:45, 3 March 2010 (UTC)

That's the function group(); this page is for group_string(). I know, it's hard to tell 'cause of how wikis handle page names, I'll make that a bit clearer! --StDoodle 15:45, 5 March 2010 (UTC)
