如何在简单 XML php 中打开、编辑子项并保存到文件

Question

This is my code

$data = simplexml_load_file("data.xml");
$data -> mysuname = $_POST["mysqluname"];
$data -> myspwd = $_POST["mysqlpwd"];
$data -> mysdb = $_POST["db_name"];
$data -> saveXml();

But when I open the data.xml I couldn't find these values But echoing $_POST[variable] prints the value, so its not null

I figured out that, the problem is with SELinux in fedora, I disabled it and everything is fine.

you should try this:

$data = simplexml_load_file("data.xml");
$data -> mysuname = $_POST["mysqluname"];
$data -> myspwd = $_POST["mysqlpwd"];
$data -> mysdb = $_POST["db_name"];
$data -> asXML("data.xml");
