What are some common methods in PHP to retrieve and display the path of an image?

To retrieve and display the path of an image in PHP, you can use the `$_SERVER['DOCUMENT_ROOT']` variable to get the root path of your web server and then concatenate it with the relative path of the image file. This way, you can dynamically generate the full path to the image and display it on your webpage.

$imagePath = $_SERVER['DOCUMENT_ROOT'] . '/images/image.jpg';
echo $imagePath;
