title: PHP - Delete last 2 characters in a loop
body: <p>I have the following which produces results for me.</p>
  
  <pre><code>foreach($authArray as $key=&gt;$value){
      $query = mysql_query("SELECT * FROM table WHERE id='$value' LIMIT 1");
      $author = mysql_fetch_assoc($query);
      echo $author['fullname'] .', ';
  }
  </code></pre>
  
  <p>It prints it out perfect, except on the last run it still adds the comma and space, is there a way i can strip this from the last result, so its:</p>
  
  <pre><code>name, name, name, name
  </code></pre>
  
  <p>Instead of the following</p>
  
  <pre><code>name, name, name, name,
  </code></pre>
  
  <p>Cheers</p>
