Include & Require
Allow for insertion of the content of one PHP file into another PHP file, before the server executes it.
Include doesn`t produce error if it can not find the file.
Include
We have a header file
header.php
<?php
echo `Welcome`
?>
To include the header file in a page / in multiple pages
<html>
<body>
<?php
include `header.php`;
?>
</body>
</html>
Require
Require is same as include, but if it can not find the file it cease execution and produce error.
