格式化json_encode()

Question

我使用json_encode()传递数据。这是我的前轮。

foreach ($result as $val) {
    $data[] = array('item'=>$val["item"]);
    $data[] = array('availability'=>$val["stocks"]););
}

输出是

[
    {
        "item": "Anchor Butter"
    },
    {
        "availability": "no"
    },
    {
        "item": "Kraft Chedder"
    },
    {
        "availability": "yes"
    }
]

我的问题是如何实现如下输出？

[
    {
        "item": "Anchor Butter",
        "availability": "no"
    },
    {
        "item": "Kraft Chedder",
        "availability": "yes"
    }
]

Answer 1

您将在每次迭代中向$data数组添加2个元素。相反，尝试如下：

foreach ($result as $val){
    $data[] = array('item'=>$val["item"], 'availability'=>$val["stocks"]));
}

Answer 2

$info=array();
while ($row = mysql_fetch_assoc($result)) {
    $info1= array();
    $info1["item"]=$row["item"];
    $info1["availability"]=$row["stocks"];
    array_push($info, $info1);  
}
print_r($info);
