title: Mysql seems to remove slashes from string
body: <p>I'm running this exact query from PHP:</p>
  
  <pre><code>UPDATE commentedText SET title='§2.', content='&lt;div class=\"pageParagraph\"&gt;&lt;p&gt;Test&lt;/p&gt;\n&lt;/div&gt;', last_changed='1430422172', image_banner_url='', active='', comments='[{"from":"0","to":"0","id":"1","CommentedText":"","comment":"New test with \"test\" :d"}]' WHERE id='5541d52beb2ea' AND appId='MyAppID' LIMIT 1
  </code></pre>
  
  <p>However when I read the row that was updated (either via PHP or MySQL Workbench), the slashes are gone. See for example </p>
  
  <pre><code>&lt;div class=\"pageParagraph\"[..]
  </code></pre>
  
  <p>which is saved to the table as</p>
  
  <pre><code> &lt;div class="pageParagraph"[..]
  </code></pre>
  
  <p>How come the slashes disappear? </p>
