PHP: Automatic Copyright Year

In website footers, we usually use some kind of copyright notice. Something like: “© 2013 NicoleJeanette.me”. In some cases, it may be tedious or we may forget to update this information, especially when updating website designs. The following snippets will help you have a more automatic function of displaying the year.

Add the snippets to the file where you have your copyright notice, it’s usually in footer.php.

If you want to show the current year only:

&copy; <?php echo date("Y") ?>
// This would look like: © 2013

If you want to show the starting year to the current year:

&copy; 2010 - <?php echo date("Y") ?>
// This would look like: © 2010 - 2013

There’s a function (that validates the information) that you can use to achieve the same information above:

<?php 
function CopyrightInfo($year = "default") {
	if (intval($year) == "default") {
		$year = date("Y"); 
	}
	if (intval($year) == date("Y")) {
		echo intval($year);
	}
	if (intval($year) < date("Y")) {
		echo intval($year) . " - " . date("Y");
	}
	if (intval($year) > date("Y")) {
		echo date("Y");
	}
}
?>

Using the function:

<?php CopyrightInfo(); ?>

It would display as: © 2013.

<?php CopyrightInfo("2010"); ?>

It would display as: © 2010 – 2013
