PHPDoc type hinting for array of objects?

In the PhpStorm IDE from JetBrains, you can use /** @var SomeObj[] */, e.g.:

/**
 * @return SomeObj[]
 */
function getSomeObjects() {...}

The phpdoc documentation recommends this method:

specified containing a single type, the Type definition informs the reader of the type of each array element. Only one Type is then expected as element for a given array.

Example: @return int[]
