Laravel 合并数组

Question

我有一个包含这个值的数组

$_logfields=["_id", "time2", "logtype", "SourceZone", "SourceIP", "DestinationIP", "Protocol", "SendBytes", "RcvPkts"];

我想从数据库中选择字段

$datas = Logss::select ("_id", "time2", "logtype", "SourceZone", "SourceIP", "DestinationIP", "Protocol", "SendBytes", "RcvPkts")->offset(10)->limit(10 )->get();

查询后我的目标是拥有这样的json数据

$tdata = [{ headName: "_id", headVal: ["32432dsfsdf34ffds","345dsfdsfcxsddfsfds34"] },{ headName: "time2", headVal: ["2/1/2019","3/2/2019"] },{ headName: "logtype", headVal: ["traffic","url"] },{ headName: "SourceZone", headVal: ["trust","untrust"] },{ headName: "SourceIP", headVal: ["192.168.1.1","192.168.5.1"] },{ headName: "DestinationIP", headVal: ["10.10.0.5","10.10.0.20"] },{ headName: "Protocol", headVal: ["udp","ICP"] },{ headName: "SendBytes", headVal: ["30","40"] },{ headName: "RcvPkts", headVal: ["5","7"]];

那么我该怎么做那个json 我所做的是

for($i=0; $i < count($_logfields); $i++){
    $headname = $_logfields[$i];
    $col[$i]['headName'] = $_logfields[$i];

    for($j=0; $j < count($datas); $j++){    
        $col[$i][$j]['headVal'] = $datas[$j][$headname];
    }
}
echo json_encode($col);

但是这个返回的是一些类似这样的东西，它不适用于我的代码

[{"headName":"_id","0":{"headVal":"5df2194d2d81db5e845586ce"},"1":{"headVal":"5df2194d2d81db5e845586cf"},"2":{"headVal": "5df2194d2d81db5e845586d0"},"3":{"headVal":"5df2194d2d81db5e845586d1"},"4":{"headVal":"5df2194d2d81db5e845586d2"},"5":{"headVal":"5df2194d2d81db5e845}" :{"headVal":"5df2194d2d81db5e845586d4"},"7":{"headVal":"5df2194d2d81db5e845586d5"},"8":{"headVal":"5df2194d2d81db5e845586d6"},"9":{"headVal":"5df21454d72be "}},{"headName":"time2","0":{"headVal":"周四， 2019 年 11 月 28 日 16:18:10 +0000"},"1":{"headVal":"2019 年 11 月 28 日星期四 16:18:12 +0000"},"2":{"headVal":"2019 年 11 月 28 日星期四 16:18:12 +0000"},"3":{"headVal":"2019 年 11 月 28 日星期四 16:18:13 +0000"},"4":{"headVal":"星期四 2019 年 11 月 28 日 16:18:13 +0000"},"5":{"headVal":"星期四 2019 年 11 月 28 日 16:18:13 +0000"},"6":{"headVal":"2019 年 11 月 28 日星期四 16:18:14 +0000"},"7":{"headVal":"2019 年 11 月 28 日星期四 16:18:14 +0000"},"8":{"headVal":"星期四 2019 年 11 月 28 日 16:18:14 +0000"},"9":{"headVal":"星期四 2019 年 11 月 28 日 16:18:15 +0000"}},{"headName":"logtype","0":{"headVal":"交通日志"},"1":{"headVal":"交通日志"},"2":{ “headVal”：“交通 LOGS"},"3":{"headVal":"流量日志"},"4":{"headVal":"流量 LOGS"},"5":{"headVal":"流量日志"},"6":{"headVal":"流量 LOGS"},"7":{"headVal":"流量日志"},"8":{"headVal":"流量 LOGS"},"9":{"headVal":"流量 LOGS"}},{"headName":"SourceZone","0":{"headVal":"tunnel"},"1":{"headVal":"tunnel"},"2":{"headVal" :"隧道"},"3":{"headVal":"隧道"},"4":{"headVal":"隧道"},"5":{"headVal":"隧道"},"6 ":{"headVal":"tunnel"},"7":{"headVal":"tunnel"},"8":{"headVal":"trust"},"9":{"headVal":"隧道"}},{"headName":"SourceIP","0":{"headVal":"172.16.10.252"},"1":{"headVal":"172.16.10.252"},"2": {"headVal":"172.16.10.252"},"3":{"headVal":"172.16.10.252"},"4":{"headVal":"172.16.10.252"},"5":{" headVal":"172.16.10.252"},"6":{"headVal":"172.16.10.252"},"7":{"headVal":"172.16.10.252"},"8":{"headVal" :"10.10.3.150"},"9":{"headVal":"10.5.5.30"}},{"headName":"DestinationIP","0":{"headVal":"10.10.0.3"}, "1":{"headVal":"10.10.0.23"},"2":{"headVal":"10.10.0.4"},"3":{"headVal":"10.10.0.26"},"4 ":{"headVal":"10.10.0.23"},"5":{"headVal":"10.10.0.4"},"6":{"headVal":"10.10.0.188"},"7": {"headVal":"10.10.0.4"},"8":{"headVal":"194.27.156.207"},"9":{"headVal":"10.10.0.144"}},{"headName": "协议","0":{"headVal":"icmp"},"1":{"headVa l":"icmp"},"2":{"headVal":"udp"},"3":{"headVal":"icmp"},"4":{"headVal":"icmp"}, "5":{"headVal":"icmp"},"6":{"headVal":"icmp"},"7":{"headVal":"icmp"},"8":{"headVal" :"udp"},"9":{"headVal":"udp"}},{"headName":"SendBytes","0":{"headVal":"60"},"1":{" headVal":"60"},"2":{"headVal":"142"},"3":{"headVal":"60"},"4":{"headVal":"60"}, "5":{"headVal":"60"},"6":{"headVal":"60"},"7":{"headVal":"60"},"8":{"headVal" :"76"},"9":{"headVal":"142"}},{"headName":"RcvPkts","0":{"headVal":"1"},"1":{" headVal":"0"},"2":{"headVal":"0"},"3":{"headVal":"0"},"4":{"headVal":"0"}, "5":{"headVal":"0"},"6":{"headVal":"0"},"7":{"headVal":"0"},"8":{"headVal" :"1"},"9":{"headVal":"0"}}]

这是从数据库接收到的数据

Answer 1

其中$arr是数据库查询的结果，你可以使用laravel集合的map函数或者这个内置的array_map函数

 $headval = ['headname' => '_id', 'headval' => array_map(function($a){return $a['_id'];},$arr)];
 $time2 = ['headname' => 'time2', 'headval' => array_map(function($a){return $a['time2'];},$arr)];
 $newArray = [$headval,$time2];

Answer 2

请更新您的查询

   $datas = Logss::select ("_id", "time2", "logtype", "SourceZone", "SourceIP", "DestinationIP", "Protocol", "SendBytes", "RcvPkts")->offset(10)->limit(10 )->get()->toArray();

然后使用下面的代码

$new_array = array();
    foreach($matches as $key=>$value){
        foreach($value as $k=>$v){

            $new_array[$k][] = $v;
        }

    }
    echo json_encode($new_array);die;
