What is the significance of using PHP tags in a PHP code snippet?

PHP tags are used to delimit PHP code within a file. It is essential to use PHP tags to indicate to the server that the enclosed code should be interpreted as PHP. Without PHP tags, the server will not recognize the code as PHP and will not execute it. It is crucial to always use PHP tags at the beginning and end of PHP code snippets to ensure proper execution.
