simple xml add attribute

Question

How can I set attributes when I add new elements in XML with PHP. My PHP code is like this:

Answer 1

Use SimpleXMLElement::addAttribute — Adds an attribute to the SimpleXML element

edit: Your use case -

     $action = $user->addChild("action","");
     // add attribut `value` here in tag action
     $action->addAttribute('value','update'); // add this

     $action->addChild("table","customers");

     $action->addChild("table_id","1");

Best example:

http://php.net/manual/en/simplexmlelement.addattribute.php

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();

?>
