This is the error I get when I run my script:

Fatal error: Access type for interface method Openable::open() must be omitted in C:\Program Files\Apache Group\Apache2\htdocs\zend\interface.Openable.php on line 3

These are my scripts:

interface Openable {
	public abstract function open();
	public abstract function close();


class Jar implements Openable {
	private $contents;
	public function __construct($contents) {
		$this->contents = $contents;
	function open() {
		print "The jar is now open<br />";
	function close() {
		print "The jar is now closed<br />";

	function openSomething(Openable $obj) {
	$objJar = new Jar('Jelly');

If I remove the abstract keyword in interface.Openable.php I don't get the error. Is it because of PHP 5.1.2 and that I need to upgrade?
