Question

我想用php创建多个json字符串数组。 Json必须像这样

[{
    app:[{"id":"3","image_title":"Fashion","image_url":"6968ec4b67315f81bbf3b893ca02a195.jpg"}],
    app2:[{"id":"3","image_title":"Fashion","image_url":"6968ec4b67315f81bbf3b893ca02a195.jpg"},
      {"id":"3","image_title":"Fashion","image_url":"6968ec4b67315f81bbf3b893ca02a195.jpg"},
      {"id":"3","image_title":"Fashion","image_url":"6968ec4b67315f81bbf3b893ca02a195.jpg"}]
}]

当我使用时

$array = array(
array( "ad1"=>
    array("id"=>"3", "image_title"=>"Fashion", "image_url"=> "6968ec4b67315f81bbf3b893ca02a195.jpg")
    ),
    array( "ad2"=>
    array("id"=>"4", "image_title"=>"Fashion", "image_url"=> "6968ec4b67315f81bbf3b893ca02a195.jpg"),
    array("id"=>"5", "image_title"=>"Fashion", "image_url"=> "6968ec4b67315f81bbf3b893ca02a195.jpg"),
    array("id"=>"6", "image_title"=>"Fashion", "image_url"=> "6968ec4b67315f81bbf3b893ca02a195.jpg")
    )
);
echo json_encode($array);

我得到的结果是

[{"ad1":{"id":"3","image_title":"Fashion","image_url":"6968ec4b67315f81bbf3b893ca02a195.jpg"}},
{"ad2":{"id":"4","image_title":"Fashion","image_url":"6968ec4b67315f81bbf3b893ca02a195.jpg"},
"0":{"id":"5","image_title":"Fashion","image_url":"6968ec4b67315f81bbf3b893ca02a195.jpg"},
"1":{"id":"6","image_title":"Fashion","image_url":"6968ec4b67315f81bbf3b893ca02a195.jpg"}}]

在id 5和6中显示0和1。

如何纠正？请帮帮我？

你的数组应该是这样的：

$array = [
    [
        'app' => [
            'id' => 3, 'image_title' => 'Fashion', // and do so on
        ],
        'app2' => [
            ['id' => 3, 'image_title' => 'Fashion',], // and do so on
            ['id' => 3, 'image_title' => 'Fashion',], // and do so on
            ['id' => 3, 'image_title' => 'Fashion',], // and do so on
        ],
    ]
];

echo json_encode($array);

然后输出应该与你描述的类似：

[{
    app:[{"id":"3","image_title":"Fashion","image_url":"6968ec4b67315f81bbf3b893ca02a195.jpg"}],
    app2:[{"id":"3","image_title":"Fashion","image_url":"6968ec4b67315f81bbf3b893ca02a195.jpg"},
      {"id":"3","image_title":"Fashion","image_url":"6968ec4b67315f81bbf3b893ca02a195.jpg"},
      {"id":"3","image_title":"Fashion","image_url":"6968ec4b67315f81bbf3b893ca02a195.jpg"}]
}]

它可能有点不同，例如，键被封装在双引号中，而整数（实际上是整数，而不是包含数字的字符串）将没有双引号。双引号和其他特殊字符可以在JSON字符串中进行转义（\"）。

希望它有所帮助。
