Question

我正在编写第一页，其中包含PHP和HTML混合。此页面显示访问者的IP地址（ipv4或ipv6）。 PHP脚本工作正常，但HTML代码显示为文本而不是呈现。

<!doctype html>
<html>
<title>mioipv6.it</title>
<body>
<?php
header('Content-type: application/json');
if ( array_key_exists('addr', $_GET) )
$ip = $_GET['addr'];
else
$ip = $_SERVER['REMOTE_ADDR'];
$v6 = preg_match("/^[0-9a-f]{1,4}:([0-9a-f]{0,4}:){1,6}[0-9a-f]{1,4}$/", $ip);
$v4 = preg_match("/^([0-9]{1,3}\.){3}[0-9]{1,3}$/", $ip);
if ( $v6 != 0 )
$type = "IPv6";
elseif ( $v4 != 0 )
$type = "IPv4";
else
$type = "unknown";
echo json_encode(array("Il tuo indirizzo" => $ip, "Tipo" => $type));
?> 
<a href='http://ipv6-test.com/validate.php?url=referer'><img src='http://ipv6-test.com/button-ipv6-small.png' alt='ipv6 ready' title='ipv6 ready' border='0' /></a>
</body>
</html>
