<?php $api_key = '........';      //steam api key, required work $lines = file('parse1.txt');                        //reads in file list of user numbers $game_id = 550;                                     //steam game id, 440 tf2  foreach ($lines $usernumber) {                    //loops line line $link = 'http://api.steampowered.com/iplayerservice/getownedgames/v0001/?key=' . $api_key . '&steamid=' . $usernumber . '&format=json'; $json = file_get_contents($link);                   //reads link (this ^) $data = json_decode($json); foreach ($data->response->games $game) {      if ($game->appid == $game_id) {         $playtime = $game->playtime_forever;         if (($playtime < 5400) && ($playtime > 1)) {         //echo 'playtime ', $usernumber, ' ' . $playtime."<br>";                 echo $usernumber."<br>";                     }         }     } } ?>

the response object in json not contain games array.

you'll want add more defense code handle situations external data not meet expectations:

if (!empty($data->response->games)) {     foreach ($data->response->games $game) {          if ($game->appid == $game_id) {             $playtime = $game->playtime_forever;             if (($playtime < 5400) && ($playtime > 1)) {             //echo 'playtime ', $usernumber, ' ' . $playtime."<br>";                     echo $usernumber."<br>";                         }             }         }     } } else {     echo 'games missing!'; }
