實現多餘的字符用...代替

1.通過css實現

<div style="text-overflow:ellipsis; white-space:nowrap; overflow:hidden;">奧沙水庫就會盡快</div>

 2.php方式實現

function cut_str($str, $length)
{
    if (mb_strlen($str, 'UTF-8') > $length) {
        return mb_substr($str, 0, $length, 'UTF-8') . '...';
    } else {
        return $str;
    }
}
