Proper way to denote array data type for phpDocumentor?

Which of the following is the proper way to document the return type of this method for phpDocumentor?

Method 1:

/**
 * @return array Foo array.
 */
public function foo() {
    return array(1, 2, 3);
}

Method 2:

/**
 * @return integer[] Foo array.
 */
public function foo() {
    return array(1, 2, 3);
}

Also, are there any IDE implications from either method?

Edit:

It appears that both PhpStorm and Netbeans 7.1+ IDEs support the 2nd method.
