What is the significance of using <?php ?> tags in PHP code?

Using <?php ?> tags in PHP code is essential as it denotes the start and end of PHP code within a file. It allows the PHP interpreter to distinguish between PHP code and other content in the file, ensuring that only the PHP code is executed. Failure to use these tags can result in syntax errors or unexpected behavior in the code.
