Here is a basic xml file that describes a message from one person to another:
<?xml version='1.0'?>
<message>
<subject>Hello</subject>
<from>user@example.com</from>
<to>user2@example.com</to>
<body>Hello World</body>
</message>
If you create a file called test.xml with the content above then create a php file with the following, it will load in the xml file and output it as an SimpleXML object:
Will output:
<?php
$xml = simplexml_load_file("test.xml");
print_r($xml);
?>
SimpleXMLElement ObjectTo reference a variable within the xml file you can use in the normal object way, e.g. $xml->subject
(
[subject] => Hello
[from] => user@example.com
[to] => user2@example.com
[body] => Hello World
)
To change the value of a variable, you can simply do the following:
$xml->subject = "New Subject";
And to output the new XML file:
echo $xml->asXML();
which returns:
<?xml version="1.0"?>Any questions/feedback please leave a comment
<message>
<subject>New Subject</subject>
<from>user@example.com</from>
<to>user2@example.com</to>
<body>Hello World</body>
</message>
