php - Error on getting data from a JSON API -

currently i'd data json api url:

http://bitsnoop.com/api/trackers.php?hash=3ba918bf6b648bb6bec6aac716f1855451016980&json=1

i have tried following:

<?php $query = file_get_contents('http://bitsnoop.com/api/trackers.php?hash=3ba918bf6b648bb6bec6aac716f1855451016980&json=1'); $parsed_json = json_decode($query, true); foreach ($parsed_json $key => $value) {     echo $value['announce'];     echo "<br>"; } ?> 

here i'd want value of as:

announce, num_seeders, num_leechers, found, updated.

but i'm getting error:

warning: invalid argument supplied foreach() in c:\xampp\test.php on line 4

you need add user agent headers

<?php  function get_json($url, $curl = true) {     $responsestring = '';     if (!$curl) {         $responsestring = file_get_contents($url);     } else {         $ch = curl_init( $url );         $options = array(             curlopt_returntransfer => true,             curlopt_httpheader => array('content-type: application/json', 'user-agent: mozilla/5.0 (windows nt 6.3; wow64) applewebkit/537.36 (khtml, gecko) chrome/39.0.2171.95 safari/537.36') ,           );         curl_setopt_array( $ch, $options );         $responsestring =  curl_exec($ch);     }     return $responsestring; }  $url ="http://bitsnoop.com/api/trackers.php?hash=3ba918bf6b648bb6bec6aac716f1855451016980&json=1"; $query = get_json($url); $parsed_json = json_decode($query, true); foreach ($parsed_json $key => $value) {     echo $value['announce'];     echo "<br>"; } ?>
