note 94356 added to ref.mbstring

The function trim() has not failed me so far in my multibyte applications, but in case one needs a truly multibyte function, here it is. The nice thing is that the character to remove can be whitespace or any other specified character, even a multibyte character. <?php // multibyte string split function mbStringToArray ($str) { if (empty($str)) return false; $len = mb_strlen($str); $array = array(); for ($i = 0; $i < $len; $i++) { $array[] = mb_substr($str, $i, 1); } return $array; } // removes $rem at both ends function mb_trim ($str, $rem = ' ') { if (empty($str)) return false; // convert to array $arr = mbStringToArray($str); $len = count($arr); // left side for ($i = 0; $i < $len; $i++) { if ($arr[$i] === $rem) $arr[$i] = ''; else break; } // right side for ($i = $len-1; $i >= 0; $i--) { if ($arr[$i] === $rem) $arr[$i] = ''; else break; } // convert to string return implode ('', $arr); } ?> ---- Server IP: 69.147.83.197 Probable Submitter: 124.217.180.162 ---- Manual Page -- http://www.php.net/manual/en/ref.mbstring.php Edit -- https://master.php.net/note/edit/94356 Del: integrated -- https://master.php.net/note/delete/94356/integrated Del: useless -- https://master.php.net/note/delete/94356/useless Del: bad code -- https://master.php.net/note/delete/94356/bad+code Del: spam -- https://master.php.net/note/delete/94356/spam Del: non-english -- https://master.php.net/note/delete/94356/non-english Del: in docs -- https://master.php.net/note/delete/94356/in+docs Del: other reasons-- https://master.php.net/note/delete/94356 Reject -- https://master.php.net/note/reject/94356 Search -- https://master.php.net/manage/user-notes.php
