How does the "include" function work in PHP, and why might included files not be displayed in the browser?
When using the "include" function in PHP to include files, it is important to ensure that the file path is correct. If the included files are not being displayed in the browser, it could be due to incorrect file paths or permissions issues. To solve this problem, double-check the file paths in the include function and make sure that the files have the appropriate permissions for the web server to access them.
<?php
include 'path/to/your/file.php';
?>
