How can PHP be used to extract elements with specific attributes from source code?

To extract elements with specific attributes from source code using PHP, you can use the DOMDocument class to parse the HTML and then use XPath to query for elements with the desired attributes. 

// Load the source code into a DOMDocument
$doc = new DOMDocument();
$doc->loadHTML($sourceCode);

// Create a DOMXPath object to query the document
$xpath = new DOMXPath($doc);

// Query for elements with a specific attribute (e.g. class="example")
$elements = $xpath->query('//*[@class="example"]');

// Loop through the elements and do something with them
foreach ($elements as $element) {
    echo $doc->saveHTML($element) . "<br>";
}
