        ]
    }

I have already use json decode. How to get each value in this json tree? I only can get $num1 & $val1, but I still want to get the rests. Thanks.

foreach ($data['value']['num'] as $data) 
  $num1= $data[0][0];
 $val1= $data[0][1];

Answer 1

foreach ($data['value']['num'][0] as $data) {
  $num[]= $data[0];
  $val[]= $data[1];
}
