Different result when adding Header function to set the Content-type document

[eros]

page1.php (with header function)
[PHP]<?php
header("Content-type: text/vnd.wap.wml");
print "<?xml version=\"1.0\" encoding=\"Shif t-JIS\"?>";
$test = 123;
?>
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN"
"http://www.wapforum.or g/DTD/wml_1.1.xml">
<wml>
<card id="card1" title="Tutorial ">
<p>
<fieldset title="住所" >
<small>検索する時に市区 郡町村を書いてリン クを押す。</small><br/>
〒：<input type="text" name="custpostc ode" value="<?php echo $test ?>" maxlength="8"/>
〒：<input type="text" name="custpostc ode" value="456" maxlength="16"/>
</fieldset>
</p>
</card>
</wml>[/PHP]
Output:


page2.php (without header function)
[PHP]<?php
//header("Content-type: text/vnd.wap.wml");
print "<?xml version=\"1.0\" encoding=\"Shif t-JIS\"?>";
$test = 123;

〒：<input type="text" name="custpostc ode" value="456" maxlength="16"/>
</fieldset>
</p>
</card>

Heya, eros.

My guess is that the problem lies in how Opera handles that content-type. Have you tried it in other browsers?
