PHP in Ephox Edit Live

Have anyone succeeded in inserting PHP code into Ephox Edit Live under Code View? We were able to include PHP as inline snippets but not directly. Of course, I know that inserting PHP code is a security risk, but some of our customers may want it. Ephox claims they support it, but <? code ?> or <?php code ?> apparently gets stripped out while <% code %>and <!-- SSI --> doesn’t. (These codes get stripped out of this forum too, but I escaped the angle brackets).

Thanks

Michael
