mapunk Posted August 21, 2006 Share Posted August 21, 2006 I've tried working on this for a pretty long time, but I'm new to regular exprsesions so I really have no idea how to do this.Let's say I have a string like the one below. I have an array of the usernames...Let's call it $user_array. How would I go about searching for, and replacing the string under each user with a string called $replacement? Or better yet, how would I just capture the text for each user using preg_match? It needs to be able to capture multiple lines and any character thrown it's way. I don't need the whole logic behind it, just the preg_replace/preg_match statement. Thanks guys[quote][username=User1]Some notes on this user go here[username=User2]More noteson user two go here[username=User3]These are notesthat I have kept forthisparticular user[/quote] Link to comment https://forums.phpfreaks.com/topic/18232-regex-help-preg_replace/ Share on other sites More sharing options...
