What are the advantages of using a hierarchical XML structure in PHP over a variable structure?

When dealing with complex data structures in PHP, using a hierarchical XML structure can provide a clear and organized way to represent the data. This can make it easier to navigate and manipulate the data, especially when dealing with nested elements. Additionally, using XML can also make it easier to share and exchange data with other systems that support XML. 

<?php
// Sample XML data representing a hierarchical structure
$xml = <<<XML
<data>
    <user>
        <name>John Doe</name>
        <email>john.doe@example.com</email>
        <address>
            <street>Main Street</street>
            <city>City</city>
            <zip>12345</zip>
        </address>
    </user>
</data>
// Parse the XML data
$xmlData = simplexml_load_string($xml);

// Accessing data from the hierarchical XML structure
echo "User: " . $xmlData->user->name . "\n";
echo "Email: " . $xmlData->user->email . "\n";
echo "Address: " . $xmlData->user->address->street . ", " . $xmlData->user->address->city . ", " . $xmlData->user->address->zip . "\n";
?>
