Are there any specific PHP functions or libraries that are recommended for extracting data from websites?

When extracting data from websites in PHP, one recommended library is cURL, which allows you to make HTTP requests and retrieve data from a URL. Another useful library is Simple HTML DOM Parser, which helps parse HTML documents and extract specific elements. These libraries can be used in combination to effectively scrape data from websites. 

// Using cURL to fetch data from a website
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://example.com');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
curl_close($ch);

// Using Simple HTML DOM Parser to extract specific elements
include('simple_html_dom.php');
$html = str_get_html($result);
$element = $html->find('div#content', 0)->plaintext;

echo $element;
