<?php 

    $postArray ='[{"data":{"hello":"world"},"type":"1234","date":"2012-10-30 17:6:9","user":"000000000000000","time_stamp":1351587969902}, {"data":{"hello":"world"},"type":"1234","date":"2012-10-30 17:12:53","user":"000000000000000","time_stamp":1351588373519}]';
     
    
    $de_json = json_decode($postArray,TRUE);
      $count_json = count($de_json);
        for ($i = 0; $i < $count_json; $i++)
           {
                //echo var_dump($de_json);
 
                  $dt_record = $de_json[$i]['date'];
                   $data_type = $de_json[$i]['type'];
                  $imei = $de_json[$i]['user'];
                  $message = json_encode($de_json[$i]['data']);

                }
