How can the extracted values from xPath queries be efficiently stored in PHP arrays for further processing or manipulation?

To efficiently store extracted values from xPath queries in PHP arrays, you can use the DOMXPath class to query the XML document and then iterate over the results to store them in an array. You can create an associative array where the xPath query serves as the key and the extracted value as the value. This allows for easy access and manipulation of the extracted data in your PHP code. 

<?php
// Load your XML document
$xml = new DOMDocument();
$xml->load('your_xml_file.xml');

// Create a new DOMXPath object
$xpath = new DOMXPath($xml);

// Define your xPath query
$query = '//your/xpath/query';

// Execute the query to get matching nodes
$nodes = $xpath->query($query);

// Initialize an empty array to store extracted values
$extractedValues = [];

// Iterate over the matching nodes and store the extracted values in the array
foreach ($nodes as $node) {
    $extractedValues[$query] = $node->nodeValue;
}

// Now you can access and manipulate the extracted values in the $extractedValues array
print_r($extractedValues);
?>
