note 113235 added to ref.mbstring

Here's a cheap and cheeky function to remove leading and trailing *punctuation* (or more specifically "non-word characters") from a UTF-8 string in whatever language. (At least it works well enough for Japanese and English.) /** * Trim singlebyte and multibyte punctuation from the start and end of a string * * @author Daniel Rhodes * @note we want the first non-word grabbing to be greedy but then * @note we want the dot-star grabbing (before the last non-word grabbing) * @note to be ungreedy * * @param string $string input string in UTF-8 * @return string as $string but with leading and trailing punctuation removed */ function mb_punctuation_trim($string) { preg_match('/^[^\w]{0,}(.*?)[^\w]{0,}$/iu', $string, $matches); //case-'i'nsensitive and 'u'ngreedy if(count($matches) < 2) { //some strange error so just return the original input return $string; } return $matches[1]; } Hope you like it! ---- Server IP: 69.147.83.199 Probable Submitter: 86.28.217.184 ---- Manual Page -- http://php.net/manual/en/ref.mbstring.php Edit -- https://master.php.net/note/edit/113235 Del: integrated -- https://master.php.net/note/delete/113235/integrated Del: useless -- https://master.php.net/note/delete/113235/useless Del: bad code -- https://master.php.net/note/delete/113235/bad+code Del: spam -- https://master.php.net/note/delete/113235/spam Del: non-english -- https://master.php.net/note/delete/113235/non-english Del: in docs -- https://master.php.net/note/delete/113235/in+docs Del: other reasons-- https://master.php.net/note/delete/113235 Reject -- https://master.php.net/note/reject/113235 Search -- https://master.php.net/manage/user-notes.php
