Adds an attribute to the SimpleXML element.
The name of the attribute to add.
The value of the attribute.
If specified, the namespace to which the attribute belongs.

Hinweis:
Listed examples may include example.php, which refers to the XML string found in the first example of the basic usage guide.
Beispiel #1 Add attributes and children to a SimpleXML element
<?php
include 'example.php';
$sxe = new SimpleXMLElement($xmlstr);
$sxe->addAttribute('type', 'documentary');
$movie = $sxe->addChild('movie');
$movie->addChild('title', 'PHP2: More Parser Stories');
$movie->addChild('plot', 'This is all about the people who make it work.');
$characters = $movie->addChild('characters');
$character = $characters->addChild('character');
$character->addChild('name', 'Mr. Parser');
$character->addChild('actor', 'John Doe');
$rating = $movie->addChild('rating', '5');
$rating->addAttribute('type', 'stars');
echo $sxe->asXML();
?>
Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:
<?xml version="1.0" standalone="yes"?> <movies type="documentary"> <movie> <title>PHP: Behind the Parser</title> <characters> <character> <name>Ms. Coder</name> <actor>Onlivia Actora</actor> </character> <character> <name>Mr. Coder</name> <actor>El ActÓr</actor> </character> </characters> <plot> So, this language. It's like, a programming language. Or is it a scripting language? All is revealed in this thrilling horror spoof of a documentary. </plot> <great-lines> <line>PHP solves all my web problems</line> </great-lines> <rating type="thumbs">7</rating> <rating type="stars">5</rating> </movie> <movie> <title>PHP2: More Parser Stories</title> <plot>This is all about the people who make it work.</plot> <characters> <character> <name>Mr. Parser</name> <actor>John Doe</actor> </character> </characters> <rating type="stars">5</rating> </movie> </movies>
If the attribute already exists, addAttribute does nothing.
example:
<?php
$xml_string = <<<XML
<?xml version="1.0" encoding="UTF-8"?>
<root>
<item id="foo">
<root>
XML;
$xml = simplexml_load_string($xml_string);
$xml->item->addAttribute('id', 'bar');
echo $xml->asXML();
?>
The above examples will output:
<?xml version="1.0" encoding="UTF-8"?>
<root>
<item id="foo">
<root>
