How can regular expressions be utilized in PHP to make URLs clickable in text?

Regular expressions can be utilized in PHP to search for URLs within text and then replace them with clickable links. By using a regular expression pattern to match URLs in the text, you can then use the `preg_replace` function to replace them with `<a>` tags that turn them into clickable links. 

$text = &quot;Check out this website: https://www.example.com&quot;;
$pattern = &#039;/(https?:\/\/[^\s]+)/&#039;;
$replacement = &#039;&lt;a href=&quot;$1&quot; target=&quot;_blank&quot;&gt;$1&lt;/a&gt;&#039;;
$linked_text = preg_replace($pattern, $replacement, $text);

echo $linked_text;
