Php decoding Jsonarray from jsonobject

Question

Hi i am working on php webservices and i am stucked with receving jsonarray as post request . i am able to receve other objects apart from jsonarray easily. My json structure looks like the following

{
    "full_name" :"amn",
    "phone":"9902",
    "educational_details":[
    {"board":"a","grade":"b","percentage":"21.0"},
    {"board":"a1","grade":"b1","percentage":"22.0"}
    ]
}

Here is my following php code to decode json

$data = json_decode(file_get_contents('php://input'), true);

          $fullname=$data['full_name'];           
          $phone=$data['phone'];
          $email=$data['email'];
          $nativeaddress=$data['native_address'];
          $fresher=$data['fresher'];
          $skills=$data['skills'];
          $resumeUri=$data['resume_uri'];
          $obj = $data['educational_details'];

          $obj1=json_decode($obj,true);

          echo "arrayval".$obj1;

Any Help would be much appreciated.. Thanks in advance :)

Answer 1

This was the solution as given by someone above and worked perfectly

foreach($obj as $val){
              echo "<br>Board = " .$val['board']." <br>Grade = ".$val['grade'] ."<br> Percentage =".$val['percentage'];
                             $board=$val['board'];
                             $grade=$val['grade'];
                             $percentage=$val['percentage'];
                             $percentageval = floatval($percentage);
}
