尝试这个：
function truncate($string, $chars = 50, $terminator = ' …') {
$cutPos = $chars - mb_strlen($terminator);
$boundaryPos = mb_strrpos(mb_substr($string, 0, mb_strpos($string, ' ', $cutPos)), ' ');
return mb_substr($string, 0, $boundaryPos === false ? $cutPos : $boundaryPos) . $terminator;
}
但是您需要确保正确设置内部编码。
