I am busy developing a site that will need to be accessed by both WAP and normal browsers. The normal browser access is OK and the site is finished for that - now comes to big problem:

I need to create content based on a MySQL database for use on WAP, my only means of accessing the MySQL db is using PHP from a Linux server. I've tried a test that is supposed to display Hi on the WAP browser. This does not work it gives me the following error:
Unsupported content type: text/html
The code below is the original code I tried. After that I included Header("Content-type: text/wml"); with Content-type changing from text/wml to text/xml to xml to wml to xml/wml to no avail.

<?

print "<?xml version=\"1.0\" encoding=\"UTF-8\"?>
<!DOCTYPE wml PUBLIC \"-//WAPFORUM//DTD WML 1.1//EN\" \"http://www.wapforum.org/DTD/wml_1.1.xml\">

<wml>
<template>
<do type=\"options\" name=\"prev\" label=\"Back\">
<prev/>
</do>
</template>
<card title=\"Page Title\" id=\"first\">
<p align=\"center\">Hi</p>
</card>
</wml>
";

?>

Your help would be greatly appreciated

you want something more like this....

<?
header("Content-type: text/vnd.wap.wml");
echo("<?xml version=\"1.0\"?>\n");
echo("<!DOCTYPE wml PUBLIC \"-//WAPFORUM//DTD WML 1.1//EN\""
." \"http://www.wapforum.org/DTD/wml_1.1.xml\">\n");
?>

<wml>
<template>
<do type="options" name="prev" label="Back">
<prev/>
</do>
</template>
<card title="Page Title" id="first">
<p align="center">Hi</p>
</card>
</wml>

The stuff inbetween the <? ?> is php, outside is WML. Not the line that reads
header("Content-type: text/vnd.wap.wml");
This tells the client browser that WML follows. Note - you'll need a wml browser to view your pages.
