title: PHP MYSQL VALUE variable
body: <p>I would like to save for value from the database in a <code>string</code> . I learn PHP and still just do not understand this grade</p>
  
  <pre><code>$db_user = $database-&gt;runSQLQuery("SELECT * FROM users");
  while($feld = mysql_fetch_array($db_user)){ 
     $save= $feld['username'].",";     
  }
  // Tom,Anne,Alf
  echo $save;
  </code></pre>
  
  <p>Unfortunately, it saves me a value here: <code>tom,</code></p>
