You can convert your JSON data to <code>object</code> or <code>array</code>. 
Use php <code>json_decode</code> function to do it. 

Convert to object

<pre><code>$data = '{"Students":
[{"ID":"600","datetime":"26-11-2019 04-32-31","age":"12"},
{"ID":"601","datetime":"26-11-2019 04-32-31","age":"13"},
{"ID":"602","datetime":"26-11-2019 04-32-31","age":"12"},
{"ID":"603","datetime":"26-11-2019 04-32-31","age":"14"}
]}';

$obj = json_decode($data);

foreach ($obj-&gt;Students as $key =&gt; $value) {
 echo $value-&gt;age; 
}
</code></pre>

If you want convert JSON data to array put second argument (true) to <code>json_decode</code>. function

<pre><code>$data = '{"Students":
 [{"ID":"600","datetime":"26-11-2019 04-32-31","age":"12"},
 {"ID":"601","datetime":"26-11-2019 04-32-31","age":"13"},
 {"ID":"602","datetime":"26-11-2019 04-32-31","age":"12"},
 {"ID":"603","datetime":"26-11-2019 04-32-31","age":"14"}
 ]}';

 $array = json_decode($data, true);

 foreach ($array['Students'] as $key) {
 echo $key['age']; 
 }
</code></pre>

I get the following data in JSON format. 

<pre><code>{"Students":
[{"ID":"600","datetime":"26-11-2019 04-32-31","age":"12"},
{"ID":"601","datetime":"26-11-2019 04-32-31","age":"13"},
{"ID":"602","datetime":"26-11-2019 04-32-31","age":"12"},
{"ID":"603","datetime":"26-11-2019 04-32-31","age":"14"}
]}
</code></pre>

I want to write a PHP script to insert this data in MYSQL. 

I'm not sure how to write the Loop to go through this data.

I tried the following code, and it does not work. 

<pre><code>//encode the Json request.
$obj = json_decode($content);

foreach($obj as $key){
 // $email = $decode['RouteID'];

}
</code></pre>
