php- How to send $_POST data to xml?

Question

I have a php file that contains:

<?php
$no = $_POST['no'];
$url = "http://domain.tld/answer.xml";
?>

The $url stores a URL that links to an xml file and that xml files is like:

<?xml version="1.0" encoding="UTF-8"?>
<vxml version = "2.1" > 
<Call> </Call>
</vxml>

I want to pass the $_POST['no'] to my xml file. Suppose if $_POST['no'] is 9999988888, then the tag in xml should be like:

<Call>9999988888</Call>

Can anyone tell how to do this? :)

that xml file is on my own server.

Are you trying to save the value to an XML file on the same saver or do you try to send it to a static XML file on another server? You can not modify files on another HTTP Server, you always have to call a script that saves the data to the file. — ThW, Oct 15 '14 at 07:54

you could use simplexml, as:

$no = $_POST['no'];
$xml = simplexml_load_file('your_xml_file.xml');
$xml->Call = $no; 
//save/update your xml
$xml->asXML('your_xml_file.xml');

You need to generate the xml using PHP.

First of all, rename your .xml to .php.

Then, start it using

<?php
header('Content-type: text/xml');
?>

When you reach your call tag, change it to :

<Call><?php echo intval($_GET['no']); ?></Call>

Note: I've assumed your no is a number. If it's not, remove intval. It's nice to have it as it will protect you from injections.

At last, call your XML file using :

 $url = "http://domain.tld/answer.php?no=8877454";

Your XML should have some keywords, i.e.

<?xml version="1.0" encoding="UTF-8"?>
<vxml version = "2.1" > 
<Call>{{CALL}}</Call>
</vxml>

In your PHP File, just fetch this XML & use str_replace to replace those keywords,

<?php
$no = $_POST['no'];
$url = "http://domain.tld/answer.xml";
$xml = file_get_contents($url);
$newXML = str_replace("{{CALL}}", $no, $xml);
header('Content-type: text/xml');
echo $newXML;
?>
