title: Add double quote between text seperated by comma
body: <p>I'm trying to figure out how to add double quote between text which separates by a comma.</p>
  
  <p>e.g. I have a string</p>
  
  <pre><code>$string = "starbucks, KFC, McDonalds";
  </code></pre>
  
  <p>I would like to convert it to</p>
  
  <pre><code>$string = '"starbucks", "KFC", "McDonalds"';
  </code></pre>
  
  <p>by passing $string to a function. Thanks!</p>
  
  <p>EDIT: For some people who don't get it...
  I ran this code</p>
  
  <pre><code>$result = mysql_query('SELECT * FROM test WHERE id= 1');
  $result = mysql_fetch_array($result);
  
  echo ' $result['testing']';
  </code></pre>
  
  <p>This returns the strings I mentioned above...</p>
