What are the drawbacks of not using include in PHP code?

The main drawback of not using include in PHP code is that it can lead to code duplication and maintenance issues. By not utilizing include, you may end up repeating the same code in multiple files, making it harder to update or make changes in the future. Using include allows you to separate your code into reusable modules, improving code organization and maintainability.

// Example of using include to include a header file in your PHP code
include 'header.php';

// Your PHP code goes here

// Example of using include to include a footer file in your PHP code
include 'footer.php';
