php原生怎样下载？

1.整个网页的html界面源码下载:

xiazai.php

<html>
<head>
<meta charset ="utf-8">
<title></title>
</head>
<body>
<form method="post" action="xiazai.php">
<input type="submit" name="xz" id="xz" value="下载" />
</form>
</body>
</html>
<?php
//文件下载
//readfile
$filename ="xiazia.php";
if(!empty($_POST["xz"])){
    $fileinfo = pathinfo($filename);
    header('Content-type: application/x-'.$fileinfo['extension']);
    header('Content-Disposition: attachment; filename='.$fileinfo['basename']);
    header('Content-Length: '.filesize($filename));
    readfile($thefile);
    exit();
}
?>

显示后果为:点击下载按钮，下载整个页面:
