Can't serve XHTML-MP with PHP

I can get an index.xhtml file to work which is valid XHTML-MP. However, when I change the extension to .php it give 500 internal server error.

I tried to set the header to both the XHTML-MP headers and the standard XHTML headers and no luck with either attempts.

Could this mean that my server does not support the XHTML-MP MIME type? I know that XHTML works on my server and I think that XHTML-MP is a subset of XHTML so shouldn't it work if I serve it as XHTML.

Can anyone help me with this? Thanks!

My site is at http://mobi.randomthoughts.ws/

Sample XHTML page works OK:

http://mobi.randomthoughts.ws/index.xhtml

I get a blank page, absolutely no output on http://mobi.randomthoughts.ws

For the index.xhtml page, you should add the following within the <head> of the document:

html4strict Code:

Original - html4strict Code
<meta http-equiv="Content-Type" content="application/xhtml+xml; charset=utf-8" />

<meta http-equiv="Content-Type" content="application/xhtml+xml; charset=utf-8" />

As for your 500 error:
Have you made any changes to .htaccess or server?
Can you use PHP normally?

I have no problems with using PHP on my server...many, many PHP files are working flawlessly.

The XHTML-MP checks out:

http://validator.w3.org/check?uri=h...=Inline&group=0

Here is my PHP file that I am trying to execute:

Code:


<?PHP 
header('Content-type: application/vnd.wap.xhtml+xml');
?><?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//WAPFORUM//DTD XHTML Mobile 1.0//EN" "http://www.wapforum.org/DTD/xhtml-mobile10.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
<head>
<meta http-equiv="Content-Type" content="application/xhtml+xml; charset=utf-8" /> 
<title>City Guide</title>
	<link href="style.css" rel="stylesheet" type="text/css"/>
</head>
<body>
<p>
<img src="meal.gif" alt=""/><b>Restaurants:</b><br/>
Your current location is Market Street, San Francisco.<br/>
Choose restaurants within 1 mile:
</p>
<table>
<tr class="blue">
<td><p class="nowrap">1 <a accesskey="1" href="find.html">American (2 Restaurants)</a></p></td>
</tr>
<tr>
<td><p class="nowrap">2 <a accesskey="2" class="bluetext" href="find.html">Chinese (2 Restaurants)</a></p></td>
</tr>
<tr class="blue">
<td><p class="nowrap">3 <a accesskey="3" href="find.html">Frence (2 Restaurants)</a></p></td>
</tr>
<tr>
<td><p class="nowrap">4 <a accesskey="4" class="bluetext" href="find.html">Italian (2 Restaurants)</a></p></td>
</tr>
<tr class="blue">
<td><p class="nowrap">5 <a accesskey="5" href="find.html">Japanese (2 Restaurants)</a></p></td>
</tr>
<tr>
<td><p class="nowrap">6 <a accesskey="6" class="bluetext" href="find.html">Mexican (2 Restaurants)</a></p></td>
</tr>
</table>
<p><a class="darkblue" href="more.html">More</a>
</p> 
</body>
</html>

Do I need to have MIME type for XHTML-MP installed in PHP? I've never dealt with that before.

No you shouldn't have to.

Have you tried echoing the XML declaration -
if PHP has short tags enabled it can get confused.

php Code:

Original - php Code
<?php header('Content-type: application/vnd.wap.xhtml+xml'); echo '<?xml version="1.0" encoding="UTF-8"?>'."\n"; ?>

<?php
header('Content-type: application/vnd.wap.xhtml+xml');
echo '<?xml version="1.0" encoding="UTF-8"?>'."\n";
?>

Saying that, don't know why you get a 500 error -
that should throw a parse error..

Would question your use of tables in this instance,
but that is another issue..

Cool. Here is a working PHP template to output XHTML-MP. It is validated here http://validator.w3.org/check?uri=http%3A%2F%2Fmobi.randomthoughts.ws%2F&charset=%28detect+automatically%29&doctype=Inline&group=0

I am not using the:

header('Content-type: application/vnd.wap.xhtml+xml');

for now so I can test it in the browser. Should I use that later on? I have seen a couple of articles on HTTP_ACCEPT to test whether the browser will accept it or not. IE tries to "open" the XHTML files. FF can handle it appropriately. This is just a template that has nothing to do with my website, but I am going to get the content now and fill in this little template. I will post back once I get the PHP running in this template, validate it through W3C, and test it on a couple of mobile phones.

Does anybody have any "gotchas" that I should be weary about like this one for what I am doing?

Code:

<?php
//      header('Content-type: application/xhtml+xml');
      echo '<?xml version="1.0" encoding="UTF-8"?>'."\n";
?><!DOCTYPE html PUBLIC "-//WAPFORUM//DTD XHTML Mobile 1.0//EN" "http://www.wapforum.org/DTD/xhtml-mobile10.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
<head>
<meta http-equiv="Content-Type" content="application/xhtml+xml; charset=utf-8" /> 
<title>City Guide</title>

Gotchas:
- tables
- you should send as "application/xhtml+xml" if the device can handle it.

However, invalid code (tag soup) will break the page and it may not display.
