title: Zend_Db_Table insert issue with large content
body: <p>I've been using Zend Framework for quite a while now, but now I have an issue that's got me puzzled. I have a table (MySQL) with just 2 columns (<code>id</code> and <code>msg</code>). The id field is an auto increment value and the msg field is a longtext type.</p>
  
  <p>The following code should work just fine for inserting a record into the table:</p>
  
  <pre><code>$t = new Zend_Db_Table('table1');
  $id = $t-&gt;insert(array('msg' =&gt; $content));
  </code></pre>
  
  <p>Whenever <code>$content</code> is just a plain string value like 'blah', it works just fine, like it should.
  But the <code>fieldtype</code> is not a longtext type for no reason, the content will be quite large.
  So now I try to place about 14kb of data in <code>$content</code>, no exception occurs, the database insert seems to have worked, but only for the first 6kb. The rest of the data is just gone?!</p>
  
  <p>When I try to use to oldfashioned <code>mysql_connect</code>, <code>mysql_query</code>, etc routines, it all works like a charm. So it's really seems to be a Zend framework issue...
  Has anybody else experienced this?</p>
