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? -- Rick Hodger
