ARRAYの作成方法は？

Question

私はARRAY（配列名： "キュー"）を作成したいPHPを使用して、このArrayListのために...私はPHPのコードと、以下の出力があります。

[ 
    {"datetime":"2016-06-16 17:32:32","qname":"5","qagent":"50","qevent":"7","info1":"2","info2":"91","info3":"1"}, 
    {"datetime":"2016-06-16 17:31:01","qname":"5","qagent":"50","qevent":"10","info1":"2","info2":"1466069459.6496","info3":"1"}, 
    {"datetime":"2016-06-16 16:28:41","qname":"5","qagent":"53","qevent":"8","info1":"2","info2":"113","info3":"1"}, 
    {"datetime":"2016-06-16 16:26:48","qname":"5","qagent":"53","qevent":"10","info1":"2","info2":"1466065606.6445","info3":"1"}, 
    {"datetime":"2016-06-16 15:47:25","qname":"5","qagent":"50","qevent":"7","info1":"4","info2":"454","info3":"1"}, 
    {"datetime":"2016-06-16 15:39:51","qname":"5","qagent":"50","qevent":"10","info1":"4","info2":"1466062787.6382","info3":"3"}, 
    {"datetime":"2016-06-16 15:27:45","qname":"5","qagent":"50","qevent":"8","info1":"5","info2":"339","info3":"1"}, 
    {"datetime":"2016-06-16 15:22:06","qname":"5","qagent":"50","qevent":"10","info1":"5","info2":"1466061721.6337","info3":"4"}, 
    {"datetime":"2016-06-16 15:18:16","qname":"5","qagent":"53","qevent":"7","info1":"2","info2":"50","info3":"1"},

    {"datetime":"2016-06-16 15:14:06","qname":"5","qagent":"50","qevent":"7","info1":"5","info2":"60","info3":"1"}, 
    {"datetime":"2016-06-16 15:13:06","qname":"5","qagent":"50","qevent":"10","info1":"5","info2":"1466061181.6318","info3":"4"}, 
    {"datetime":"2016-06-16 14:52:52","qname":"5","qagent":"53","qevent":"7","info1":"3","info2":"50","info3":"1"}, 
    {"datetime":"2016-06-16 14:52:02","qname":"5","qagent":"53","qevent":"10","info1":"3","info2":"1466059919.6275","info3":"3"}, 
    {"datetime":"2016-06-16 14:49:50","qname":"5","qagent":"28","qevent":"1","info1":"1","info2":"1","info3":"2"}, 
    {"datetime":"2016-06-16 14:25:44","qname":"5","qagent":"53","qevent":"7","info1":"47","info2":"162","info3":"1"}, 
    {"datetime":"2016-06-16 14:23:02","qname":"5","qagent":"53","qevent":"10","info1":"47","info2":"1466058176.6227","info3":"5"}, 
    {"datetime":"2016-06-16 14:22:51","qname":"5","qagent":"53","qevent":"0","info1":"15000","info2":"","info3":""}, 
    {"datetime":"2016-06-16 14:22:35","qname":"5","qagent":"50","qevent":"0","info1":"0","info2":"","info3":""}, 
    {"datetime":"2016-06-16 14:22:30","qname":"5","qagent":"53","qevent":"0","info1":"15000","info2":"","info3":""} 
] 

これは私のPHPコードです：

<?php 

$con=mysqli_connect("localhost","root",""); 
mysqli_select_db($con,"qstatslite")or die("error"); 

$q = mysqli_query($con,"SELECT * FROM queue_stats ORDER BY queue_stats_id DESC LIMIT 20"); 


$return_arr = array(); 

while ($row = mysqli_fetch_array($q)) { 
//$return_arr['queue_stats_id'] = $row['queue_stats_id']; 
$row_array['datetime'] = $row['datetime']; 
$row_array['qname'] = $row['qname']; 
$row_array['qagent'] = $row['qagent']; 
$row_array['qevent'] = $row['qevent']; 
$row_array['info1'] = $row['info1']; 
$row_array['info2'] = $row['info2']; 
$row_array['info3'] = $row['info3']; 

    array_push($return_arr,$row_array); 
} 

$output = json_encode(array('return_arr' => $return_arr)); 
echo json_encode($return_arr); 

?> 

リストの前にタイトルを「キュー」にしたいとします。あなたの助けに感謝します。 ty

ここにはJSONの配列があります。 PHPの配列に変換したいのですが、これには特別な機能があります。

http://php.net/manual/en/function.json-decode.php

用法：

$queue = json_decode($json); 

一度行って、あなたがPHPのlist()機能を使用することができます。

http://php.net/manual/en/function.list.php

用法：

$info = array('coffee', 'brown', 'caffeine'); 
list($drink, $color, $power) = $info; 
echo "$drink is $color and $power makes it special.\n"; 

- あなたがPHPにJSONを翻訳したい場合は、あなたが既に知っているように見えるjson_encode();を、使用することができます。ただし、json_encode()を2回使用しているため、問題が発生する可能性があります。あなたが戻ってjavascriptまたは何にこのJSONを送信した場合

$return_arr = array(); 

while ($row = mysqli_fetch_array($q)) { 
//$return_arr['queue_stats_id'] = $row['queue_stats_id']; 
$row_array['datetime'] = $row['datetime']; 
$row_array['qname'] = $row['qname']; 
$row_array['qagent'] = $row['qagent']; 
$row_array['qevent'] = $row['qevent']; 
$row_array['info1'] = $row['info1']; 
$row_array['info2'] = $row['info2']; 
$row_array['info3'] = $row['info3']; 

    array_push($return_arr,$row_array); 
} 

$output = json_encode(array('queue' => $return_arr)); 
echo $output; 

さて、それは次のようになります。

//get values 
jsonData.queue.datetime; 
jsonData.queue.qagent; 

あなたは、単に再びPHPの配列にそれをデコードした場合、それを

<?php 
    $queue = json_decode($output)['queue']; 
?>
