将POST保存到文件中

I'm using tinymce to edit inline content and then save it via AJAX to a file with PHP.

The problem I'm having is that tinymce fills empty tags, like , so, when I go to PHP, the POST I recieve it's something like this:

<td align=\"center\">1,42m<\/td><td align=\"center\">","nbsp;<\/td>

I save the content into a file with file_put_contents, but the string got cutted, so content file is:

<td align="center">1,42m</td><td align="center">

and then stop writting.

Does anyone have a clue of how could I fix it?

Edit

Problem solved, more or less.

Before initialize tinymce, I find any empty td and then add a zero-space char (HTML &#8203;)

Anyway, I left post open for a couple of days, hoping for a better solution.
