[PHP] WML/WAP and PHP
Here's a fun little thing I discovered, possibly a bug in PHP itself?
To output a WAP page you must output a content-type header else the phone's
browser won't recognise the page. Dead simple. Use:
header("Content-type: text/vnd.wap.wml");
And all is well and good as long as you use echo/printf etc to output your
page. The second you deviate out of PHP and back to HTML the content-type
gets overwritten with a text/html, and so the page doesn't work. ASP used
to be able to cope with this, is it a bug or something I'm doing wrong?

Re: [PHP] WML/WAP and PHP
Hi Rick,
you are not doing anything wrong. You just have to send the proper
content-type depending on what you're outputing. For example if you want to
produce a gif image you have to use header("Content-type: image/gif");
There's nothing wrong with it as PHP can't predict what you want to do.
text/html is set as default simply because it's the type most users in most
cases need.

Yes, I know that. But what I'm saying is that eg.
?php
header("Content-type: text/vnd.wap.wml");
?
wml
card
pHello world!/p
/card
/wml
...gets put out with a text/html content type as opposed to the specified
text/vnd.wap.wml. Having said that, I just tried it on the linux machine and
it worked fine. A Windows thing?

RE: [PHP] WML/WAP and PHP
I seem to remember reading something very recently, possibly on this list,
about WML. IIRC, if you drop out of PHP at any point the rest of the
document gets treated as text/html. Try something like
?php
header("Content-type: text/vnd.wap.wml");
echo("wmlcardpHello world!/p/card/wml");
?
and see if it works.
Sorry to be vague, but I didn't pay *that* much attention to it at the time!

Re: [PHP] WML/WAP and PHP
are you sure that there's nothing in the file in before you call the
header() function? The situation you describe could happen if there was an
empty line at the begining of the file and the warnings were turned off.
When I tried your code it worked as expected:
C:\c:\php4\php test.php
X-Powered-By: PHP/4.0.4
Content-type: text/vnd.wap.wml
wml
card
pHello world!/p
/card
/wml
C:\

Hmmm - you might need to start checking details of your configuration. I've had
no problems doing a lot of WML work in PHP and it's always correctly returned
the content-type I've set using header on 4.0.3pl1 (OpenBSD) and 4.0.3 / 4.0.4
(Win32).
Do you have anything like output buffering turned on? I doubt that's causing
the problem as I use output buffering semi-frequently[0] but it can't hurt to
check.
[0] neat hack - use ob_content_length() to tell when you've output almost as
much data as the phone can handle (find this by doing a browser detect) so you
can stop looping over a recordset and emit the Next/Prev page headers instead).
