Normally, yes -- but because the PHP grammar matches the <?php tag,  
and enters a new context after this tag, it will not see the other  
rules you include (as these are only in the parent context of the <? 
php match) -- the match for <?php you do in your new grammar is a  
look-ahead match, meaning that this itself does not “eat” the  
construct, and thus leaves it for the PHP grammar.

Again this is a problem with having the PHP grammar match <?php … ?>  
itself.

I’d suggest you clone the PHP grammar, remove the matching of <?php  
… ?> from this clone, and then include that instead of the stock PHP  
grammar -- long-term there will be more flexible solutions for  
augmenting language grammars.
