note 40791 added to function.preg-replace

For all the people out there that don't understand a single bit of this regular expression replacement stuff (including myself), and just want to take a string and remove all special characters from it, leaving it with only spaces, underscores, letters, and numbers...here is the code! $string = preg_replace('/[^\w\s\-]/','',$string); To tell you the truth, I don't completely understand it but I did some research and mixed perl with php and it works and that's all that matters. ---- Manual Page -- http://www.php.net/manual/en/function.preg-replace.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+40791 Delete -- http://master.php.net/manage/user-notes.php?action=delete+40791&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+40791&report=yes Search -- http://master.php.net/manage/user-notes.php
