How can PHP scripts on one website search and retrieve specific data from HTML pages on another website for use?

To search and retrieve specific data from HTML pages on another website, you can use PHP to send HTTP requests to the target website, retrieve the HTML content, and then parse the HTML to extract the desired data. This can be achieved using PHP libraries like cURL or file_get_contents to fetch the HTML content, and then using DOMDocument or regular expressions to extract the specific data. 

<?php
// URL of the website to fetch data from
$url = 'https://www.example.com';

// Fetch the HTML content of the website
$html = file_get_contents($url);

// Parse the HTML content to extract specific data
// For example, extracting all the links from the HTML
$dom = new DOMDocument();
$dom->loadHTML($html);

$links = [];
foreach ($dom->getElementsByTagName('a') as $link) {
    $links[] = $link->getAttribute('href');
}

// Use the extracted data as needed
print_r($links);
?>
