title: Steam api user data: Only works for one steam id, else DOESNT WORK
body: <p>I'm really new to php and doesnt understand much with apis.. 
  I wrote this code: </p>
  
  <pre><code>&lt;?php
  $steamkey = "xxxxxxxx"; // censored I use the right steamkey
  $id_user = "76561198059606697"; // only this steam id works
  
  $apifr = "http://api.steampowered.com/ISteamUserStats/GetUserStatsForGame/v0002/?appid=730&amp;key=".$steamkey."&amp;steamid=".$id_user;
  
  $data = file_get_contents($apifr); // put the contents of the file into a variable
  
  $test = json_decode($data);
  
  echo print_r($test-&gt;playerstats-&gt;stats[0]-&gt;value, true);
  ?&gt;
  </code></pre>
  
  <p>the result is the total_kills of the player steam id:</p>
  
  <pre><code>49999
  </code></pre>
  
  <p>The result "49999" are the right total_kills of the player in csgo, which actually works just fine, but if I try different steamids it doesnt work anymore...</p>
  
  <p>Could someone please help me and explain why or give another solution to use the steam api for csgo player stats?</p>
  
  <p>Thank you all</p>
  
  <p>I tried more then 10 different right steam ids, however they doesnt work... 
  Some people have names instead of for example "1231943812" as a steam id, it doesnt work too, I dont know how to use the names too</p>
