class Helper extends CController{ public static function truncate_utf8_string($string, $length, $etc = '...'){ $result = ''; $string = html_entity_decode(trim(strip_tags($string)), ENT_QUOTES, 'UTF-8'); $strlen = strlen($string); for ($i = 0; (($i < $strlen) && ($length > 0)); $i++){ if ($number = strpos(str_pad(decbin(ord(substr($string, $i, 1))), 8, '0', STR_PAD_LEFT), '0')){ if ($length < 1.0){ break; } $result .= substr($string, $i, $number); $length -= 1.0; $i += $number - 1; }else{ $result .= substr($string, $i, 1); $length -= 0.5; } } $result = htmlspecialchars($result, ENT_QUOTES, 'UTF-8'); if ($i < $strlen){ $result .= $etc; } return $result; } }
然后就可以在自己的代码中引用了Helper::truncate_utf8_string('XXXXXXXXXXX',10,'.......');
如果出现问题可以在config/main.php中加入在import引入要夹在扩展的目录
类似:
'import'=>array( 'application.models.*', 'application.components.*', 'application.extensions.*', 'application.extensions.yii-mail.*', ),
