What does the (?P<href> ...... ) syntax mean in the regex pattern?

The (?P<href> ...... ) syntax in a regex pattern is used to create a named capturing group. This allows you to easily reference the matched content by a specific name, in this case "href". This can be useful when extracting specific parts of a string for further processing or manipulation. 

&lt;?php
$string = &#039;&lt;a href=&quot;https://www.example.com&quot;&gt;Example&lt;/a&gt;&#039;;
$pattern = &#039;/&lt;a href=&quot;(?P&lt;href&gt;.*?)&quot;&gt;.*?&lt;\/a&gt;/&#039;;
preg_match($pattern, $string, $matches);

echo &quot;Href: &quot; . $matches[&#039;href&#039;]; // Output: https://www.example.com
?&gt;
