How can PHP be used to loop through and extract specific values from an XML file?

To loop through and extract specific values from an XML file using PHP, you can use the SimpleXML extension which provides an easy way to interact with XML data. You can load the XML file using simplexml_load_file() function, then iterate through the XML elements using foreach loop to extract the desired values based on the XML structure. 

$xml = simplexml_load_file('data.xml');

foreach($xml->children() as $child) {
    // Extract specific values based on XML structure
    $value1 = $child->element1;
    $value2 = $child->element2;

    // Do something with the extracted values
    echo $value1 . ' - ' . $value2 . '<br>';
}
