title: Using commas in a CONCAT php mysql update
body: <p>I have to perform a query similar to:</p>
  <pre><code>&lt;?php
  //....connect to database
  $old = &quot;a,b,c,d&quot;;
  $new = &quot;e,f,g,h&quot;;
  
  $insert = &quot;UPDATE TABLE SET FIELD = CONCAT(&quot; . $old . &quot;, &quot; . $new . &quot;) WHERE something = 'something';
  mysql_query($insert);
  ?&gt;
  </code></pre>
  <p>So basically, I want to append the current database entry with the 'new' string which contains commas. But since the CONCAT function uses commas I'm having trouble.</p>
  <p>Does anyone have any tips to accomplish this?</p>
