How can a beginner ensure that their PHP script effectively extracts and manipulates specific data from an HTML source?

To ensure that a PHP script effectively extracts and manipulates specific data from an HTML source, a beginner can use the PHP Simple HTML DOM Parser library. This library allows for easy parsing of HTML documents using CSS selectors, making it simpler to target and extract the desired data. 

<?php
// Include the Simple HTML DOM Parser library
include('simple_html_dom.php');

// Load the HTML source into a variable
$html = file_get_html('http://www.example.com');

// Find specific elements in the HTML using CSS selectors
$element = $html->find('div#specificElement');

// Manipulate the extracted data as needed
foreach($element as $e) {
    echo $e->plaintext;
}
?>
