Syntax Highlighting Problem

I have integrated the fckeditor syntax highlighting plugin from http://psykoptic.com/blog/post/2008/12/ ... ditor.aspx for SyntaxHighlighter.

The issue is that FckEditor is stripping my code escapes when I save. So

$sql = 'SELECT user_id, username FROM '.$prefix.'_users WHERE user_id <= \'20\' AND user_id != \'1\'';
