What best practices should be followed when filtering and extracting data from XML to CSV in PHP?

When filtering and extracting data from XML to CSV in PHP, it is important to properly parse the XML data, extract the necessary information, and format it correctly for CSV output. Using PHP's SimpleXML extension can simplify the process of parsing XML data. Additionally, utilizing functions like fopen, fputcsv, and fclose can help in writing the extracted data to a CSV file. 

<?php

// Load the XML file
$xml = simplexml_load_file('data.xml');

// Open a CSV file for writing
$csvFile = fopen('output.csv', 'w');

// Write the header row to the CSV file
fputcsv($csvFile, array('Name', 'Age', 'Email'));

// Loop through each record in the XML data
foreach ($xml->record as $record) {
    // Extract the necessary information
    $name = (string) $record->name;
    $age = (int) $record->age;
    $email = (string) $record->email;

    // Write the extracted data to the CSV file
    fputcsv($csvFile, array($name, $age, $email));
}

// Close the CSV file
fclose($csvFile);

?>
