How can PHP be used to extract specific parts of a URL for form prepopulation?

To extract specific parts of a URL for form prepopulation in PHP, you can use the $_SERVER['REQUEST_URI'] variable to get the current URL, and then use functions like parse_url() and parse_str() to extract specific parts such as query parameters. Once you have extracted the desired values, you can use them to prepopulate form fields. 

$url = $_SERVER['REQUEST_URI'];
$queryString = parse_url($url, PHP_URL_QUERY);
parse_str($queryString, $params);

// Use the extracted parameters to prepopulate form fields
echo '<input type="text" name="name" value="' . $params['name'] . '">';
echo '<input type="email" name="email" value="' . $params['email'] . '">';
