PHP json\u encode-创建json数组

您只需在php中创建一个2d数组。

$payload =  array (
    "query" => array(
         array(
             "date" => "11/01/2017...12/31/2017",
             "other sub key" => "other sub value"
         )
    ),
    "other main key" => array(
         array(
             "other sub key" => "other sub value",
             etc...
         )
    )
);

应该是这样的

$array = array(
    'query' => array(
        array('Date' => '11-01-2017')
        )
    );


echo '<pre>';
print_r(json_encode($array, JSON_PRETTY_PRINT));

后果

{
    "query": [
        {
            "Date": "11-01-2017"
        }
    ]
}

$payload = json_encode($payload, JSON_PRETTY_PRINT);
