What is the correct way to retrieve the href value from an <a> tag using DOM in PHP?

To retrieve the href value from an <a> tag using DOM in PHP, you can use the DOMDocument class to load the HTML content and then use DOMXPath to query for the <a> tag and retrieve its href attribute value. This allows you to extract the URL from the <a> tag and use it in your PHP code.

$html = &#039;&lt;a href=&quot;https://www.example.com&quot;&gt;Click here&lt;/a&gt;&#039;;

$dom = new DOMDocument();
$dom-&gt;loadHTML($html);

$xpath = new DOMXPath($dom);
$aTag = $xpath-&gt;query(&#039;//a&#039;)-&gt;item(0);

if ($aTag) {
    $href = $aTag-&gt;getAttribute(&#039;href&#039;);
    echo $href;
}
