Change Footer Text in the Admin

Sometimes the admin area of WordPress needs to be customized. One way to start is to change the text in the footer.

<?php

	add_filter('admin_footer_text', 'change_admin_footer_text_left', 1, 1);
	function change_admin_footer_text_left( $text ) {
		$text = 'Look over there &rarr;';
		return $text;
	}
	
	add_filter('update_footer', 'change_admin_footer_text_right', 99, 1 );
	function change_admin_footer_text_right( $text ) {
		$text = 'Hello!';
		return $text;
	}

?>
