如何将php数组转换为json格式

例如，您好，我有下面的json格式。我需要生成一个php数组来构建这个json

{
"posts":
    [
    {
    "detial" : {
        "titel": "web design",
        "date-publish" : "2015-02-08",
        "pic-thumbnail" : "small-web-desing-jpg",
        "pic-medium" : "medium-web-desing-jpg"
    },
    "content" : {
        "description" : "description web design post",
        "content" : "web design is modern technology in world"
    }
    }
    ]
}

---

请展示一个PHP数组的例子，构建这个json很容易

只需使用PHP的

json\u decode（）

函数即可实现

最后，将json_encode（）返回数组保存到变量

输出：

Array
(
    [posts] => Array
        (
            [0] => Array
                (
                    [detial] => Array
                        (
                            [titel] => web design
                            [date-publish] => 2015-02-08
                            [pic-thumbnail] => small-web-desing-jpg
                            [pic-medium] => medium-web-desing-jpg
                        )

                    [content] => Array
                        (
                            [description] => description web design post
                            [content] => web design is modern technology in world
                        )

                )

        )

)

$results = json_decode('{

  "posts": [{

    "detial" : {

      "titel": "web design",
        "date-publish" : "2015-02-08",
        "pic-thumbnail" : "small-web-desing-jpg",
        "pic-medium" : "medium-web-desing-jpg"

    },

    "content" : {

      "description" : "description web design post",
      "content" : "web design is modern technology in world"

    }

  }]

}', true);

echo "<pre>".print_r($results, true)."</pre>";

PHP代码：

Array
(
    [posts] => Array
        (
            [0] => Array
                (
                    [detial] => Array
                        (
                            [titel] => web design
                            [date-publish] => 2015-02-08
                            [pic-thumbnail] => small-web-desing-jpg
                            [pic-medium] => medium-web-desing-jpg
                        )

                    [content] => Array
                        (
                            [description] => description web design post
                            [content] => web design is modern technology in world
                        )

                )

        )

)

$results = json_decode('{

  "posts": [{

    "detial" : {

      "titel": "web design",
        "date-publish" : "2015-02-08",
        "pic-thumbnail" : "small-web-desing-jpg",
        "pic-medium" : "medium-web-desing-jpg"

    },

    "content" : {

      "description" : "description web design post",
      "content" : "web design is modern technology in world"

    }

  }]

}', true);

echo "<pre>".print_r($results, true)."</pre>";

$results=json\u decode（'{
“员额”：[{
“细节”：{
“titel”：“网页设计”，
“发布日期”：“2015-02-08”，
“图片缩略图”：“小型网页设计jpg”，
“pic媒体”：“媒体网页设计jpg”
},
“内容”：{
“说明”：“说明网页设计帖子”，
“内容”：“网页设计是世界上的现代技术”
}
}]
}",对),；
echo“”。打印（$results，true）。“”；

使用PHP函数json_decode（）生成PHP数组

$jsonData=json\u解码（'{
“员额”：[{
“细节”：{
“titel”：“网页设计”，
“发布日期”：“2015-02-08”，
“图片缩略图”：“小型网页设计jpg”，
“pic媒体”：“媒体网页设计jpg”
},
“内容”：{
“说明”：“说明网页设计帖子”，
“内容”：“网页设计是世界上的现代技术”
}
}]
}",对),；
回声“；
打印（jsonData）；

$obj=json\u encode（$your\u string\u here，true）
