class Example_Class {

	public function __construct( $strings ) {
		$this->strings = $strings;
		foreach( $this->strings as $string ) {
			add_action( $string[ 'hook' ], array( $this, 'echo_strings' ) );
		}
	} // End function __construct()

	public function echo_strings() {
		$hook = current_filter();
		foreach ( $this->strings as $string ) {
			if ( $string['hook'] == $hook ) {
				echo $string['message'] . "<br />\n";
			}
		}
	}

} // End class Example_Class
