PHP read Zip XML file

Using PHP we can read, write files. we can also upload and create new files.
But what if you have to read a XML file which is present in an ZIP Archive.
The following function shows how to read data of XML file from an ZIP Archive.

function readZippedXML($archiveFile, $dataFile) {
    // Create new ZIP archive
    $zip = new ZipArchive;

    // Open received archive file
    if (true === $zip->open($archiveFile)) {
        // If done, search for the data file in the archive
        if (($index = $zip->locateName($dataFile)) !== false) {
            // If found, read it to the string
            $data = $zip->getFromIndex($index);
            // Close archive file
            $zip->close();
            // Load XML from a string
            // Skip errors and warnings
            $xml = DOMDocument::loadXML($data, LIBXML_NOENT | LIBXML_XINCLUDE | LIBXML_NOERROR | LIBXML_NOWARNING);
            // Return data without XML formatting tags
            return strip_tags($xml->saveXML());
        }
        $zip->close();
    }

    // In case of failure return empty string
    return "";
}

 The usage of the function is as follows:

 readZippedXML("word/document.zip", "word/document.xml");

 This function will get all the data of the XML file from the zip and save in a new file where the zip is present.
