embedded php snippet won't parse/validate in XHTML

[markbfernandez]

I have an "Update Customer" form that doesn't work as .xhtml. Here's
where it stops working:

<input type="text" name="ud_first" id="ud_first"
value="<? echo "$first"?>" />
-------^

When the browser hits the < after value, it thinks I'm starting another
tag before I finish my input tag. Fair enough. I switch the <'s for
$lt; and then it stops here:

<input type="text" name="ud_first" id="ud_first"
value="&lt;? echo "$first"?&g t;" />
-------------------^

Switching the $ to $ doesn't help.

I can get this page to work if I change it to a .php file instead of
..xhtml. That can't be my only option?!?

Did you try the original file (with ...value="<? echo "$first"?>" ...) with
a .php extension?

The server is probably not configured to pass .xhtml through the PHP
interpreter, so it serves the PHP source code (which is not (X)HTML and
cannot be parsed as such).
You can only validate the output generated by PHP, not the PHP source code.

You've nested your double-quotes, but the parser doesn't know that. Try
value="<? echo '$first'?>" or value='<? echo "$first"?>'

PHP isn't supposed to validate directly as HTML or XHTML. It contains
code that is supposed to be parsed and executed at the server end,
producing output that then goes on to the user agent to be rendered or
validated, with no sign of the PHP code remaining.

The browser should never see that code, because it has to be executed on
the server.

Configure the server to parse .xhtml files for PHP. And consider to use
<?php instead of <?, short open tags are unreliable.

As explained it shouldn't hit that. Your php code will be useless at least.

Well, encoding the " would be more rewarding, but still your php is
useless.
About the php: Why put <? echo "$first";?? ??? <? echo $first; ?(or even
better <?php echo $first; ?>) seems more appropriate to put it lightly.

Nope. You will have to parse it as php offcourse, or remove the
php-snippets from the code. You've got the very unattractive option to tell
your web server to parse every .html, .xhtml, or .whatsinaname through php,
but it will result in a large unwanted overhead and load on the server, not
to mention it's hardly portable. Possible, but I'd strongly advise against
it.

A better question is: why do you want the .xhtml extension? If it's just
about 'friendlier' urls: the actual filenames can have very little to do
with the urls. Look at mod_rewrite for apache and the like.
