Get PNR status using Alagu's API

get-pnr-status.php

<?php
error_reporting(1);
//$url = "http://pnrapi.alagu.net/api/v1.0/pnr/6359817259?jsonp=parseJSON";
$url = "http://pnrapi.alagu.net/api/v1.0/pnr/6359817259";

$ch = curl_init($url);
//curl_setopt($ch, CURLOPT_HEADER, TRUE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);       
curl_close($ch);

$out_arr = json_decode($output);

//var_dump($output);

echo "<pre>";
print_r($out_arr);
echo "</pre>";


echo "example  " . $out_arr->status; 
?>

is there any way we can get the pnr status data from https://pnrstatus.com or https://railenquiry.in in json format ?
railenquiry send and receives request by ajax but they have a strong ip blocking system, is there any other way ? The above code is also not working.
