How can PHP be used to extract specific data from a text string and format it as a hyperlink?

To extract specific data from a text string in PHP and format it as a hyperlink, you can use regular expressions to find the data and then concatenate it into a hyperlink format. You can use the `preg_match` function to extract the desired data and then construct a hyperlink using that data. 

<?php
$text = "Visit our website at www.example.com for more information.";
$pattern = '/www\.(.*?)\s/';
if (preg_match($pattern, $text, $matches)) {
    $url = $matches[0];
    echo "<a href='http://$url'>$url</a>";
}
?>
