DOMDocument::load – PHP – Getting attribute value

I have many div tags pulled from a string through php, each of them having a unique id and a subjective class. I am trying to get the id and class of each of the divs but am not too sure how I would do this.

HTML:

<div id='x1y1' class = 'classname'></div><div id = 'x2y1' class = 'classname1'>

so far I have tried

$html = new DOMDocument();
$html->loadHTML($boardDataStripSlashes);
$elements = $html->getElementsByTagName('div');

but have not been able to find anything on how to get the actual id’s and classes of the selected elements.

You need to use DOMElement::getAttribute to retrieve attributes of elements.

foreach($elements as $element) { 
  $id = $element->getAttribute('id');
  $className = $element->getAttribute('class');
  // ...
}
