PHP Markdown Extra already does this for PHP code. But it's not  
following closely the PHP syntax, it's following the processing  
instruction syntax of xml. So this will be left alone:

     <?php echo "Hello World" ?>

while this will be wrapped in a paragraph:

     <?php echo preg_replace('/(?> W+)/', '_', "Hello World") ?>

because according to the XML spec, a processing instruction stops at  
the first `?>` (quoted or not), and what follows is taken as text.  
This match the web browser behaviour about processing instructions in  
HTML and XML.

So while it supports PHP, there is some sort of limitation to that.  
Which bring the question: what should be the rules for `<!`, `<@`,  
and `<%` support; and how far should we go with all these syntaxes?
