从PHP数据中获取信息

问题描述：

I have no idea even what this is called so had no idea what to search for. I do apologise if this already exists.

I have information that I can get from going to a specific URL. It displays with something that looks like this:

 {"loading":false,"playing":true,"position":5730,"duration":211875,"index":0,"repeat":false,"shuffle":false,"volume":1,"context":null,"contexts":[],"track":{"artists":[{"name":"R3hab","uri":"spotify:artist:6cEuCEZu7PAE9ZSzLLc2oQ"},{"name":"Vinai","uri":"spotify:artist:4mrBetqy378Jf1y6NLszlx"}],"disc":0,"duration":212000,"image":"spotify:image:9ab80608da23ad97a5fd1cd8285f7a9239169c9d","images":[[64,"spotify:image:544aab2c02ea3ece23145ac3fdb78649e1181cad"],[300,"spotify:image:9ab80608da23ad97a5fd1cd8285f7a9239169c9d"],[600,"spotify:image:8537cde9090567164f449b25c00ad0c40e5c7325"]],"name":"How We Party - Original Mix","number":1,"playable":true,"popularity":67,"starred":false,"explicit":false,"availability":"premium","album":{"uri":"spotify:album:2IhQHv3MS8iq26We33dLdQ"},"local":false,"advertisement":false,"placeholder":false,"uri":"spotify:track:2b0N6oW4f87wNr9uahicc2"}}

If you scroll half through you'll see:

"name":"How We Party - Original Mix

I need a PHP script that would find the name of the track and displays it like this:

How We Party - Original Mix

Beware that the code has the word "name" in it several times i.e. name of album, which I don't need. The position of order is always the same so that may help.

I have no idea how to even start going about this, so any help would be greatly appreciated.

我甚至不知道这是什么，所以不知道要搜索什么。如果这已经存在，我很抱歉。 p>

我可以从转到特定网址获得相关信息。它显示的内容如下所示： p>

  {“loading”：false，“playing”：true，“position”：5730，“duration”：211875，“index  “：0，” 重复 “：假，” 洗牌 “：假，” 体积 “：1，” 上下文 “：NULL，” 上下文 “：[]，” 轨道 “：{” 艺术家 “：[{” 名称“：  “R3hab”， “URI”： “的Spotify：艺术家：6cEuCEZu7PAE9ZSzLLc2oQ”}，{ “名称”： “威奈”， “URI”： “的Spotify：艺术家：4mrBetqy378Jf1y6NLszlx”}]， “盘”：0， “持续时间”：  212000， “图像”： “的Spotify：图像：9ab80608da23ad97a5fd1cd8285f7a9239169c9d”， “图像”：[[64， “Spotify的：图像：544aab2c02ea3ece23145ac3fdb78649e1181cad”]，[300， “Spotify的：图像：9ab80608da23ad97a5fd1cd8285f7a9239169c9d”]，[600，“Spotify的：图像 ：8537cde9090567164f449b25c00ad0c40e5c7325“]]，”名称“：”我们如何聚会 - 原创混音“，”数字“：1，”可玩“：真实，”人气“：67，”已加星标“：虚假，”明确“：虚假，” 可用性 “：” 溢价 “ ”专辑“：{ ”URI“： ”Spotify的：专辑：2IhQHv3MS8iq26We33dLdQ“}， ”本地“：假的， ”广告“：假的， ”占位符“：假的， ”URI“：” Spotify的：  track：2b0N6oW4f87wNr9uahicc2“}} 
  code>  pre> 
 
 如果你向前滚动一半 我会看到： p> 
 
 
 “name”：“How We Party  -  Original Mix 
  code>  pre> 
 
 我需要一个PHP 找到轨道名称的脚本，并显示如下： p> 
 
 
  How We Party  -  Original Mix 
  code>  pre> 
 
 请注意代码中有几个单词“name”，即专辑名称，我不需要。 订单的位置总是相同的，这可能有所帮助。 p> 
 
 我不知道如何开始这样做，所以任何帮助将不胜感激。   p>

That string is JSON. To parse it you would use json_decode(). Then you can access it like an object (or an array if you pass true as the second parameter).

$str = '{"loading":false,"playing":true,"position":5730,"duration":211875,"index":0,"repeat":false,"shuffle":false,"volume":1,"context":null,"contexts":[],"track":{"artists":[{"name":"R3hab","uri":"spotify:artist:6cEuCEZu7PAE9ZSzLLc2oQ"},{"name":"Vinai","uri":"spotify:artist:4mrBetqy378Jf1y6NLszlx"}],"disc":0,"duration":212000,"image":"spotify:image:9ab80608da23ad97a5fd1cd8285f7a9239169c9d","images":[[64,"spotify:image:544aab2c02ea3ece23145ac3fdb78649e1181cad"],[300,"spotify:image:9ab80608da23ad97a5fd1cd8285f7a9239169c9d"],[600,"spotify:image:8537cde9090567164f449b25c00ad0c40e5c7325"]],"name":"How We Party - Original Mix","number":1,"playable":true,"popularity":67,"starred":false,"explicit":false,"availability":"premium","album":{"uri":"spotify:album:2IhQHv3MS8iq26We33dLdQ"},"local":false,"advertisement":false,"placeholder":false,"uri":"spotify:track:2b0N6oW4f87wNr9uahicc2"}}';

// object
$obj = json_decode($str);
echo $obj->track->name;

// array
$obj = json_decode($str, true);
echo $obj['track']['name'];
