json parsing with php foreach

Reinventing the wheel, are we? Why not simply use:

$jsonObj = json_decode($jsonString);//returns stdClass instance, just an object
$jsonArr = json_decode($jsonString, true);//converts object to associative array

Read more on json_decode here... It's quite easy to use, really

If you decode the data to an array, you could loop through the data like so

while($item = array_shift($jsonArr))
{
    foreach ($item as $key => $value)
    {
        echo $key.' => '.$value."\n";
    }
}

Or simply use any old for/foreach loop on an object, its a traversable object anyway (though it doesn't implement the Traversable interface)

First step is to convert to an array

$data = json_decode($json);

Once you've got the array, you can then loop through it and check the values

$keepers = array();
foreach ($data as $item) {
  if ($item->placement->department_id == 101) {
    $keepers[] = $item;
  }
}

Use json_decode

  $arr = json_decode($jsonstring, true);

then use foreach loop

foreach($arr as $val) {
    if($val['placement']['department_id'] == "101") {
       //display what u want
    }
}

Probably something like:

$data = json_decode($your_json);

foreach($data as $object) {
    echo 'This is the name: ' . $object->name . PHP_EOL ;
}

$data = json_decode($json, true)

Then whatever info you want out you get out with the foreach loop

foreach ($data->id as $id)
{
echo $id;
}

With that you can set any variable like $data->nik as $nik or whatever you want then echo them back

usr this

foreach ($data->id as $id)
{
echo $id;
}
