Since you're looking for input, specifically on the compromise, let's try
to figure out what's possible. The RFC proposes .phpp files that can only
include other .phpp files. Others want .phpp files that can include .php
files. There are two ways I can think of to accomplish this.
1. an ini switch. This is a bad idea, because it causes code written under
one setting to be impossible to use in the other setting.
2. 3 file types.<?php,<?phpp,<?php~p (read:<?php almost pure) We'd need
something better than that last one, but what it means is that _this_ file
is pure php, but it may include an embedded script somewhere.
Between those two options, I would choose 2. Just to be clear, if I had a
third choice, which was to make no change, it would be #3.
The second thing that still needs nailing down as far as implementation is
how to determine parsing mode. If it has to be specified at include time,
then we're putting the burden on whoever writes the autoloader to know what
kind of file it is. If it has to be specified in php.ini, or in the sapi
configuration, then I'm putting the burden on the administrator. I want to
allow the developer who writes the file to specify its parsing mode.
The two ways I see for developers to do so is to use variations on the
<?php header of the file, or by file extension. I prefer variations on the
<?php header, because file extension still depends on configuration in
order to work, so involves admins in the decision of how to parse the php
files that I write.
<?php means just what it does now.
<?phpp means, disallow ?>, and error if there is anything before the
header. The RFC specifies an additional restriction, throw error if I
include file with<?php header.
<?phpo (open to suggestions for the text of this header) means disallow ?>,
and error if there is anything before the header.

Hi,
I normally only read the discussions, instead of participate but I have a short question about #2:
What is, if you mix the specified open tags?
Look at this file:
--- test.php
<?php
/* ...snip... */
?>
...snip...
<?phpp
/* ...snip... */
--- EOF
Would this error out? Would this be ignored?
(not that this kind of file should be written like this, but theoretically, it is possible)
Cheers,
Jannik
