title: Looking for a PHP/Ajax/MySQL code snippet to add/edit tags - same as stackOverflow
body: <p>I'm in the middle of adding a tagging system to my website. I want to be able to easily add/edit items tags.</p>
  
  <p>My current tags table structure is:</p>
  
  <pre><code>Table: Item
  Columns: ItemID, Title, Content
  
  Table: Tag
  Columns: TagID, Title, Tag_Counter
  
  Table: ItemTag
  Columns: ItemID, TagID
  </code></pre>
  
  <p>I really like the implementation of the tagging in StackOverflow, can anyone direct me a code snippet I can use (PHP/Ajax/MySQL)?</p>
  
  <p>I know, its a tough one...</p>
  
  <p>Thanks,</p>
  
  <p>Roy.</p>
