设置相同的键值json PHP [重复]

Question

我需要与我的 java 类中的解析器 json 进行通信，以使用图像填充网格视图。下面的php代码正在输出：

{"posts":["http://fisioterapeutacamila.com/iMoveis/img/apto01.jpg",
"http://fisioterapeutacamila.com/iMoveis/img/apto01.jpg",
"http://fisioterapeutacamila.com/iMoveis/img/apto01.jpg",
"http://fisioterapeutacamila.com/iMoveis/img/apto01.jpg",    
"http://fisioterapeutacamila.com/iMoveis/img/apto01.jpg"]}

应该怎么写才能设置相同的键值“images”输出？：

{"posts":[{"images":"http://fisioterapeutacamila.com/iMoveis/img/apto01.jpg", 
"images":"http://fisioterapeutacamila.com/iMoveis/img/apto01.jpg",
"images":"http://fisioterapeutacamila.com/iMoveis/img/apto01.jpg",
"images":"http://fisioterapeutacamila.com/iMoveis/img/apto01.jpg",
"images":"http://fisioterapeutacamila.com/iMoveis/img/apto01.jpg"}]}

PHP 文件：

$sql = "SELECT * FROM iMoveis";
$result = mysqli_query($mysqli, $sql);

$response = array();
$images = array();

while($row = mysqli_fetch_assoc($result)){

  $images[] = $row['img1'];
  $images[] = $row['img2'];
  $images[] = $row['img3'];
  $images[] = $row['img4'];
  $images[] = $row['img5'];

}

$response['posts'] = $images;

echo json_encode($response, JSON_UNESCAPED_SLASHES);

在一个对象中有两次相同的键是无效的。他们只会互相覆盖。你能做的最好的就是让它成为你数组中的一个键：

$images = array('images' => array());

while($row = mysqli_fetch_assoc($result)){

  $images['images'][] = $row['img1'];
  $images['images'][] = $row['img2'];
  $images['images'][] = $row['img3'];
  $images['images'][] = $row['img4'];
  $images['images'][] = $row['img5'];
}

它会输出这样的东西（注意转义）：

{
    "posts":{
        "images":[
            "http:\/\/fisioterapeutacamila.com\/iMoveis\/img\/apto01.jpg",
            "http:\/\/fisioterapeutacamila.com\/iMoveis\/img\/apto01.jpg",
            "http:\/\/fisioterapeutacamila.com\/iMoveis\/img\/apto01.jpg",
            "http:\/\/fisioterapeutacamila.com\/iMoveis\/img\/apto01.jpg"
        ]
    }
}

根据 cmets，对象数组：

$images = array();

while ($row = mysqli_fetch_assoc($result)) {
    $images[] = array('image' => $row['img1']);
    $images[] = array('image' => $row['img2']);
    $images[] = array('image' => $row['img3']);
    $images[] = array('image' => $row['img4']);
    $images[] = array('image' => $row['img5']);
}

产生以下输出：

{

    "posts":[
        {
            "image":"http:\/\/fisioterapeutacamila.com\/iMoveis\/img\/apto01.jpg"
        },
        {
            "image":"http:\/\/fisioterapeutacamila.com\/iMoveis\/img\/apto01.jpg"
        },
        {
            "image":"http:\/\/fisioterapeutacamila.com\/iMoveis\/img\/apto01.jpg"
        },
        {
            "image":"http:\/\/fisioterapeutacamila.com\/iMoveis\/img\/apto01.jpg"
        },
        {
            "image":"http:\/\/fisioterapeutacamila.com\/iMoveis\/img\/apto01.jpg"
        }
    ]

}
