❮ PHP Keywords

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.
