CodeIgniter's Text Helper has an ellipsize () method that is useful for filtering HTML tags and truncating text. However, it does not support Chinese very well, and garbled codes appear when used in Chinese.

The following netizens have modified function ellipsize () to make it support Chinese:

In CI 2.1.3, modify the ci_2.1.3\ system\ helpers\ text_helper.php file

Function ellipsize ($codepage = 'UTF-8', $str, $max_length, $position = 1, $ellipsis ='...') {/ / Strip tags $str = trim (strip_tags ($str)); / / Is the string long enough to ellipsize? If (mb_strlen ($str, $codepage) 1)? 1: $position; if ($position = 1) {$end = mb_substr ($str, 0,-($max_length-mb_strlen ($beg, $codepage), $codepage);} else {$end = mb_substr ($str,-($max_length-mb_strlen ($beg, $codepage), $max_length, $codepage);} return $beg.$ellipsis.$end;}

This code mainly replaces substr and strlen with mb_substr and mb_strlen, so it can support Chinese truncation very well.
