What are some best practices for organizing and manipulating data retrieved from external websites using PHP?

When organizing and manipulating data retrieved from external websites using PHP, it is essential to properly parse and structure the data to make it easier to work with. One best practice is to use PHP libraries like SimpleHTMLDom or cURL to fetch and extract the data from the external website. Once the data is retrieved, you can use functions like preg_match, preg_match_all, or XPath to extract specific information from the HTML content. 

// Example using SimpleHTMLDom to fetch and extract data from an external website
include('simple_html_dom.php');

$url = 'https://www.example.com';
$html = file_get_html($url);

// Extract specific data from the HTML content
$titles = [];
foreach($html->find('h2') as $element){
    $titles[] = $element->plaintext;
}

// Display the extracted data
foreach($titles as $title){
    echo $title . '<br>';
}
