TAdvMemo with PHP JS and HTML

Hello,
I plan to upgrade an aging editor (HTML PHP JavaScript...) using SynEdit; my trouble is that the syntax highlighting is totally messed up when the document is a mix of PHP Javascript and HTML, though I use an AdvMemoStylerManager and the corresponding stylers.
It seems the demos propose a single language style at a time. And the help is not talkative on the topic.
Did I miss sthg ?
Thank you,
Olivier de Saint Leger

The TAdvMemo styler is designed to work with a single syntax style per opened file in TAdvMemo.
