PHP: getAttribute() all attributes

Question

I can get the attribute of the tag tragetting ID by:

$tag_id = $tag->getAttribute('id');

But I want to get all attributes, not just id. How can I do this? I tried getAttribute("*") but it did not work (obviously).

I dont have any experiences on it, but I found two posts from SO, stackoverflow.com/questions/2385834/…, stackoverflow.com/questions/1338692/…, I hope it helps — Andrew

You can use the public $attributes property from the DOMNode element that the DOMElement inherits from. See also here in the documentation: DOMNode::$attributes

Code example:

$document = <<<DOCUMENT
<div id='one' style='width: 10px'></div>
DOCUMENT;

$document = DOMDocument::loadXML($document);
$element = $document->getElementsByTagName('div')->item(0);

$attributes = $element->attributes;
for ($i = 0; $i < $attributes->length; $i++) {
    $item = $attributes->item($i);
    echo 'There is an attribute called: "' . $item->nodeName . '" with value: ' . $item->nodeValue . PHP_EOL;
}

See also the eval.in that I created: https://eval.in/494934
