Question

你好我需要在php中写一个json文件，就像这样。我遵循了几个教程，但我不明白如何正确地放置括号：

{"data": [
    {
        "album": "OK Computer",
        "artist": "Radiohead",
        "first": true,
        "id": "okcomputer",
        "image": "okcomputer.png",
        "tracklist": [
            "Airbag",
            "Paranoid Android",
            "Subterranean Homesick Alien",
            "Exit Music (For a Film)",
            "Let Down",
            "Karma Police",
            "Fitter Happier",
            "Electioneering",
            "Climbing Up the Walls",
            "No Surprises",
            "Lucky",
            "The Tourist"
        ],
        "url": "https://itunes.apple.com/us/album/ok-computer/id696736813?i=696737042&uo=4&at=1l3v7Hz",
        "year": "1997"
    }
]}

怎么可能？谢谢！

Answer 1

如果您将数据定义为普通的PHP数组，那么您可以使用json_encode函数为您执行此操作。见http://php.net/manual/en/function.json-encode.php

例如：

constexpr

Answer 2

如果你想在JSON中存储一些PHP数据，你必须把它放到一个数组中，然后像你的情况一样使用json_encode函数

Answer 3

尝试这个

<?php
$output=array();
$data=array();
$item=array();
$item['album']="OK Computer";
$item['other']="same as album";
$tracklist=array('a','b','c');
$item['tracklist']=$tracklist;
array_push($data,$item);
$output['data']=$data;
echo json_encode($output);
?>

输出：

{
    "data": [{
        "album": "OK Computer",
        "other": "same as album",
        "tracklist": ["a", "b", "c"]
    }]
}

使用PHP格式化JSON
