PHP require_once Keyword
Example
Use require_once to add a footer to a page:
<!DOCTYPE html>
<html>
<body>
<h1>Welcome to my home
page!</h1>
<p>Some text.</p>
<p>Some more text.</p>
<?php
require_once
'footer.php';?>
</body>
</html>
Definition and Usage
The require_once keyword is used to embed PHP code from another file. If the file is
not found, a fatal error is thrown and the program stops. If the file was already included
previously, this statement will not include it again.
