方法二,自定义函数去除
function cutstr_html($string, $sublen){ $string = strip_tags($string); $string = preg_replace ('/\n/is', '', $string); $string = preg_replace ('/ | /is', '', $string); $string = preg_replace ('/ /is', '', $string); preg_match_all("/[\x01-\x7f]|[\xc2-\xdf][\x80-\xbf]|\xe0[\xa0-\xbf][\x80-\xbf]|[\xe1-\xef][\x80-\xbf][\x80-\xbf]|\xf0[\x90-\xbf][\x80-\xbf][\x80-\xbf]|[\xf1-\xf7][\x80-\xbf][\x80-\xbf][\x80-\xbf]/", $string, $t_string); if(count($t_string[0]) - 0 > $sublen) $string = join('', array_slice($t_string[0], 0, $sublen))."…"; else $string = join('', array_slice($t_string[0], 0, $sublen)); return $string; }
