我能从php文件中读取xml吗？ [关闭]

Question

I have apps that read online settings, and until now these settings are stored in xml. So my app read it's setting straight forward:

"http://foo.net/app/setting.xml"

But I want it to be easier to maintain, and store a lot of data in the database, So im thinkink of replacing ../app/setting.xml with something like ../setting.php where I in the php file would do something like

<?php

include mysql stuff ..

$bookid = $_GET['id'];
read database based on $bookid;

?>

<?xml version="1.0" encoding="utf-8"?>
<book>
<name><?php echo $row['name']; ?></name>
<published><?php echo $row['published']; ?></published>
</book>

Is it doable? Do I have to care about header stuff like header expires and cache?

Answer 1

It is doable. You can send your XML headers by

header("Content-Type: application/xml"); 

before any output.

<?php
header("Content-Type: application/xml");

...
$bookid = $_GET['id'];
...

?>

**here your XML.**

Now you can handle it as a normal xml file.
