title: UPDATE cell to be empty MYSQL PHP
body: <p>Looked around on Google and Stack Overflow, maybe I'm just blind though.
  Is there a way to UPDATE a table cell with an " " (empty) value. 
  Let's say like:</p>
  
  <pre><code>mysql_query("UPDATE table SET cellname = ' ' WHERE id = '$idneeded'");
  </code></pre>
  
  <p>Any help much appreciated. </p>
