mysql数据
php代码:
$res_ip = mysql_query("select * from ip order by id DESC limit 0,5");while($row_ip = mysql_fetch_array($res_ip)){ $ip_ip[] = intval($row_ip['ip']); $time_ip[] = date($row_ip['time']);}$data_ip = array(array("name"=>"IP流量","data"=>$ip_ip));$data_ip = json_encode($data_ip);$times_ip = json_encode($time_ip);$times_ip = str_replace('2015-', '', $times_ip);
["01-25","01-25","01-24","01-23","01-22"]
[{"name":"IP\u6d41\u91cf","data":[12632220,12735020,127350,2213488,2348888]}]
["01-22","01-23","01-24","01-25","01-26"]
[{"name":"IP\u6d41\u91cf","data":[2348888,2213488,127350,12735020,12632220]}]
用id排序! 递减或者递增!你这个应该是递增!
select * from ip order by id ASC limit 0,5 ?
id desc 改成 id asc 是不行的!
id desc 的本意是取最新数据,而 id asc 是取最旧的数据
要用 array_reverse 转置数组
$data_ip = array(array("name"=>"IP流量","data"=> array_reverse($ip_ip)));$data_ip = json_encode($data_ip);$times_ip = json_encode(array_reverse($time_ip));$times_ip = str_replace('2015-', '', $times_ip);
id排序应该就可以了啊,这个应该是按时间顺序写入的吧?
