and using script,

 <?php  $data = file_get_contents('sample.json'); $data = json_decode($data); $totaltime  = $data->route_summary->total_time; var_dump($totaltime); ?>

but gives me null output.any help,would appreciated?

the value can retrieved by,

  $totaltime  = $data['route_summary']['total_time'];

if json pass $data formatted.
