How can PHP be used to extract and display information from linked pages on a website?

To extract and display information from linked pages on a website using PHP, you can use the file_get_contents() function to retrieve the content of the linked page. Then, you can use regular expressions or a HTML parser like DOMDocument to extract specific information from the retrieved content. Finally, you can display the extracted information on your website. 

<?php
// URL of the linked page
$url = "https://www.example.com";

// Get the content of the linked page
$content = file_get_contents($url);

// Extract specific information using regular expressions
preg_match('/<title>(.*?)<\/title>/', $content, $matches);
$title = $matches[1];

// Display the extracted information
echo "Title of the linked page: " . $title;
?>
