New Comment:
people have been warned for *ages* now
that short tags are *not* xml-compliant,
so everybody still using them should be
blamed for doing so and not benn supported
in continuing using bad style ...
instead of adding extra magic i'd suggest
to emmit warnings for uses of '<?' even
if short_tags are enabled ...

Hi,
turning off short tags is not a real solution as long as PHP offically
supports them. There are tons of code out there using short tags and
there will be even more new code with short tags if this feature will
not be abolished.
Furthermore, and I have to repeat this, there is huge group of PHP
users that has no access to the php.ini settings (e.g. mod_php with
safe_mode in a shared hosting environment). Should these users be
forced to modify third-party code over and over again because the
developers of this code insist on (offically supported) short tags? For
companies and groups that offer web hosting services this is simply not
viable. You can't over web hosting with mutual exclusion of XHTML and
PHP.
And I also have to stress that again: PHP, a *hypertext preprocessor*,
is not able to parse standard compliant XHTML!
I think there are only two solutions: Doing it the hard way by wholly
removing short tags or changing PHP in a way that allows the usage of
XHTML and short tags.
A third approach to this problem is not a real solution but an option
for the user, namely switching to another scripting language.

Then just turn off short-tags.
And there won't be any change in this, as:
1. It came up numerous times on php-dev
2. It makes little sense

Hi!
I find this an extremly annoying behaviour, too. Since you can use PHP
to parse every file with nearly no loss of performance (whether it
contains PHP code or not) and only when it contains PHP-code it would
be really parsed through the PHP-parser.
To my optinion it is often done that you simply let php parse every
html-file, so the visitor cannot see if its generated dynamically or
static. Since you will have pages that are _really_ static you would
have to add php-code to simply add this "<?xml ..." which would cost
much performance.
Bye!

It is definitely not extraneous, as today PHP, despite
its claim to be a hypertext preprocessor, is not
capable of handling standard conforming XHTML
documents. Of course you can echo the ?xml-tag but
that was not my point. That would be just another
workaround for situations where your single goal is to
produce XML compliant *output*. There is an increasing
demand to keep the input files in a format that can be
processed by XML tools - most users I know of use
XHTML exactly for this reason and not for the mere fun
of adding closing tags all over the document :-)
But that is not the only problem. With the advent of
Apache 2 it will become common practice to apply
multiple filters successively to a source document,
e.g. use XSLT to produce XHTML with PHP from XML
sources and the send it to the PHP parser. What will
be PHP's answer? Don't use XML? Or enable PHP usage
through pre- and postprocessing filters that first
remove and then add xml-tags again?
To be honest, I think my suggested solution is neither
elegant nor very clever, but it should do its job.
Definitely the best solution would be to abolish all
kinds of short tag and asp tag syntax and only allow
the '<?php' and '<script..' styles. As far as I know,
there have been various discussions on that topic in
the past, so I decided not to suggest this again.
Thanks,
Sascha

This seems extraneous to me. You can simply echo the one <?xml tag
that is usually needed. No need to turn off short_tags. Just do:
<?echo '<?xml ...'?> at the top.
