PHP: DomElement->getAttribute
提问by Loreto Gabawa Jr.
How can I take all the attribute of an element? Like on my example below I can only get one at a time, I want to pull out all of the anchor tag's attribute.
如何获取元素的所有属性？就像在下面的示例中，我一次只能获取一个，我想提取所有锚标记的属性。
$dom = new DOMDocument();
@$dom->loadHTML(http://www.example.com);
$a = $dom->getElementsByTagName("a");
echo $a->getAttribute('href');
thanks!
谢谢！

$length = $a->attributes->length;
$attrs = array();
for ($i = 0; $i < $length; ++$i) {
$name = $a->attributes->item($i)->name;
$value = $a->getAttribute($name);
$attrs[$name] = $value;
}
print_r($attrs);

"Inspired" by Simon's answer. I think you can cut out the getAttributecall, so here's a solution without it:
受西蒙的回答“启发”。我认为你可以切断getAttribute电话，所以这里有一个没有它的解决方案：
$attrs = array();
for ($i = 0; $i < $a->attributes->length; ++$i) {
$node = $a->attributes->item($i);
$attrs[$node->nodeName] = $node->nodeValue;
}
var_dump($attrs);

$a = $dom->getElementsByTagName("a");
foreach($a as $element)
{
echo $element->getAttribute('href');
}

$html = $data['html'];
if(!empty($html)){
$doc = new DOMDocument();
$doc->loadHTML($html);
$doc->saveHTML();
$datadom = $doc->getElementsByTagName("input");
foreach($datadom as $element)
{
$class =$class." ".$element->getAttribute('class');
}
}
