How does include() differ from HTTP requests when including files in PHP?
When including files in PHP, the include() function is used to include and evaluate the specified file. This is different from HTTP requests, as include() directly includes the file within the current script, while HTTP requests make separate requests to the server to fetch the file. Using include() is more efficient for including files within the same server, as it does not incur the overhead of additional HTTP requests.
<?php
include('myfile.php');
?>
