How can PHP tags be correctly used in the code to ensure proper execution and readability?

To ensure proper execution and readability when using PHP tags in code, it is important to use the correct syntax. The opening PHP tag should always be <?php and the closing tag should be ?>. This helps to clearly define where PHP code begins and ends within the file, making it easier to read and understand.

&lt;?php
// Your PHP code here
