PHP: Loop on JSON?

Question

i have the following JSON:

{"Switches":["Auswahl1","Auswahl2","Auswahl3"],"Check_MK":["Auswahl1","Auswahl2","Auswahl3"],"Testgroup":["Auswahl1","Auswahl2","Auswahl3"],"Printer":["Auswahl1","Auswahl2","Auswahl3"],"CAD":["Auswahl1","Auswahl2","Auswahl3"]}

How do i loop each object while using PHP?

My thoughts were the following:

   <?php

      $jsonfile = file_get_contents('tags.json');
      echo $jsonfile . "<br><br>";
      $decode = json_decode($jsonfile);

      foreach($decode as $key => $value) {
        echo $key . $value;
      }

    ?>

Doesn't work..... Also

echo $decode[1];

and

echo $decode[1][1];

doesn't work..

You need to add a second parameter to json_decode()

This parameter returns associative array instead of existing object (if existing).

$decode = json_decode($jsonfile, TRUE);

This will convert your JSON decoded data into associative array.

$jsonfile = file_get_contents('tags.json');
echo $jsonfile . "<br><br>";
$decode = json_decode($jsonfile);

now $decode is equivalent to:

$decode = new stdClass();
$decode->Switches = array();
$decode->Switches[] = "Auswahl1";
$decode->Switches[] = "Auswahl2";
$decode->Switches[] = "Auswahl3";
$decode->Check_MK = array();
...
