php 拆分数组，之后算出每一个数组的和

$url = "http://api.1680210.com/LuckTwenty/getBaseLuckTewnty.do?issue=&lotCode=10014";$result = curlGet($url);$data = json_decode($result, true);$data = $data['result']['data'];//获取开奖号码$haoma = explode(',', $data['preDrawCode']);$caisan = array_chunk($haoma, 6);// 这边的6 ：比如一个数组有18个数字。最后得到的是3个数组， 每个数组有6个数字//算出第一数组的总和$num1all = array_sum($caisan[0]);

然后dump 出  $num1all
