What is the main difference between require() and include() in PHP?
The main difference between require() and include() in PHP is how they handle errors. require() will produce a fatal error if the file being included cannot be found, stopping the script execution. On the other hand, include() will only produce a warning and continue script execution if the file cannot be found. It is generally recommended to use require() when including files that are essential for the script to run properly.
<?php
// Using require() to include a file
require('myfile.php');
?>
