I can't believe so many people are posting answers without reading the JSON properly.

If you foreach iterate <code>$json_a</code> alone, you have an object of objects. Even if you pass in <code>true</code> as the second parameter, you have a two-dimensional array. If you're looping through the first dimension you can't just echo the second dimension like that. So this is wrong:

<pre><code>foreach ($json_a as $k =&gt; $v) {
 echo $k, ' : ', $v;
}
</code></pre>

To echo the statuses of each person, try this:

<pre><code>&lt;?php

$string = file_get_contents("/home/michael/test.json");
if ($string === false) {
 // deal with error...
}

$json_a = json_decode($string, true);
if ($json_a === null) {
 // deal with error...
}

foreach ($json_a as $person_name =&gt; $person_a) {
 echo $person_a['status'];
}

When you decode a json string, you will get an object. not an array. So the best way to see the structure you are getting, is to make a var_dump of the decode. (this var_dump can help you understand the structure, mainly in complex cases).

<pre><code>&lt;?php
 $json = file_get_contents('/home/michael/test.json');
 $json_a = json_decode($json);
 var_dump($json_a); // just to see the structure. It will help you for future cases

 echo $row-&gt;status;
 echo "\n";

The most elegant solution:

Remember that the json-file has to be encoded in UTF-8 without BOM. If the file has BOM, then json_decode will return NULL.

Alternatively:

<pre><code>$shipments = json_encode(json_decode(file_get_contents("shipments.js"), true));

It's completely beyond me that no one pointed out that your begining "tags" are wrong. You're creating an object with {}, while you could create an array with []. 

<pre><code>[ // &lt;-- Note that I changed this
 {
 "name" : "john", // And moved the name here.
 "status":"Wait"
 },
 {
 "name" : "Jennifer",
 "status":"Active"
 },
 {
 "name" : "James",
 "status":"Active",
 "age":56,
 "count":10,
 "progress":0.0029857,
 "bad":0
 }
] // &lt;-- And this.
</code></pre>

With this change, the json will be parsed as an array instead of an object. And with that array, you can do whatever you want, like loops etc.

I am using below code for converting json to array in <code>PHP</code>,
If JSON is valid then <code>json_decode()</code> works well, and will return an array,
But in case of malformed JSON It will return <code>NULL</code>,

<pre><code>&lt;?php
function jsonDecode1($json){
 $arr = json_decode($json, true);
 return $arr;
}

// In case of malformed JSON, it will return NULL
var_dump( jsonDecode1($json) );
?&gt;
</code></pre>

If in case of malformed JSON, you are expecting only array, then you can use this function,

<pre><code>&lt;?php
function jsonDecode2($json){
 $arr = (array) json_decode($json, true);
 return $arr;
}

// In case of malformed JSON, it will return an empty array()
var_dump( jsonDecode2($json) );
?&gt;
</code></pre>

If in case of malformed JSON, you want to stop code execution, then you can use this function,

<pre><code>&lt;?php
function jsonDecode3($json){
 $arr = (array) json_decode($json, true);

 if(empty(json_last_error())){
 return $arr;
 }
 else{
 throw new ErrorException( json_last_error_msg() );
 }
}

// In case of malformed JSON, Fatal error will be generated
var_dump( jsonDecode3($json) );
?&gt;
</code></pre>

I tried to parse a JSON file using PHP. But I am stuck now.
This is the content of my JSON file:
<pre class="lang-json prettyprint-override"><code>{
 &quot;John&quot;: {
 &quot;status&quot;:&quot;Wait&quot;
 },
 &quot;Jennifer&quot;: {
 &quot;status&quot;:&quot;Active&quot;
 },
 &quot;James&quot;: {
 &quot;status&quot;:&quot;Active&quot;,
 &quot;age&quot;:56,
 &quot;count&quot;:10,
 &quot;progress&quot;:0.0029857,
 &quot;bad&quot;:0
 }
}
</code></pre>
And this is what I have tried so far:
<pre class="lang-php prettyprint-override"><code>&lt;?php

$string = file_get_contents(&quot;/home/michael/test.json&quot;);
$json_a = json_decode($string, true);

echo $json_a['John'][status];
echo $json_a['Jennifer'][status];
</code></pre>
But because I don't know the names (like <code>'John'</code>, <code>'Jennifer'</code>) and all available keys and values (like <code>'age'</code>, <code>'count'</code>) beforehand, I think I need to create some foreach loop.
I would appreciate an example for this.

我尝试使用PHP解析JSON文件。但我现在被卡住了。这是我的JSON文件的内容：{    "John": {        "status":"Wait"    },    "Jennifer": {        "status":"Active"    },    "James": {        "status...
