Ckeditor does not display php tags in textarea

Question

I’m using Ckeditor, everything goes well, however, I can’t make posts ('tutorials') that contain php tags. For example:

<?php
acho 'teste';

The tag <?php is not displayed. Is there any configuration of Ckeditor itself that would solve this?

Answer 1

I found a solution here: http://komlenic.com/246/encoding-entities-to-work-with-ckeditor-3/

With this, before sending the content to the Ckeditor I’m making a character substitution:

str_replace('&', '&', $post->conteudo);
