PHP输出WAP页面怎么老是不行……<?php
error_reporting(0);
header("Content-Type:text/vnd.wap.wml;CharSet=utf-8");
echo '<?xml version="1.0" encoding="utf-8"?>';
echo '<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.3//EN" "
http://www.wapforum.org/DTD/wml13.dtd">';
echo '<wml><head>';
echo '<meta http-equiv="Content-Type\" content="text/vnd.wap.wml;charset=utf-8" />';
echo '<meta http-equiv="Cache-Control" content="Max-Age=0" />';
echo '<meta http-equiv="keywords" content="" />';
echo '</head>';
echo'<card title="WAP测试页">

</card></wml>';
?>我这是哪里错了呢？
