如何在php中解析大量的json数据解析？

I am getting the huge json data from the webservice and parsing through loop.but loop makes my website slow.Is there any other ways to fetch the json data in php?. This is my snippet.

for ($i=0; $i < count($trid) ; $i++) { 
$operator_aval=operator_routes_a($trid[$i],$Fromd);
$page1=file_get_contents($operator_aval);
$data1=json_decode($page1,true);
$opr_res=count($data1['routes']);
for ($j=0; $j < count($data1['routes']); $j++) {          
$origin=$data1['routes'][$j]['route']['origin'];
$destination=$data1['routes'][$j]['route']['destination'];
$status=$data1['routes'][$j]['route']['status'];
$service_name=$data1['routes'][$j]['route']['operator_service_name'];
// echo $origin."--".$destination."<br>";
if(($Fromname==$origin) && ($Toname==$destination) &&($status!="Unavailable-Service Left" ||  $status!="Unavailable-Cancelled")&& $service_name!=""){
    echo 'trid : '.$trid[$i].'reservation id : '.$data1['routes'][$j]['route']['reservation_id']."---".$data1['routes'][$j]['route']['travels']."<br>";
    $count++;
         }

}     
 }
