PHP code can be embedded within HTML code, making it seamless to mix dynamic and static content. PHP code is enclosed within special delimiters <?php ... ?> or <?= ... ?>.

Types of PHP Tags

<?php ... ?>: The standard PHP opening and closing tag.

<?= ... ?>: A shorthand tag to directly echo a variable or expression.
