PHPDoc type hinting for array of objects?

Question

So, in PHPDoc one can specify @var above the member variable declaration to hint at its type. Then an IDE, for ex. PHPEd, will know what type of object it's working with and will be able to provide a code insight for that variable.

<?php
  class Test
  {
    /** @var SomeObj */
    private $someObjInstance;
  }
?>

This works great until I need to do the same to an array of objects to be able to get a proper hint when I iterate through those objects later on.

So, is there a way to declare a PHPDoc tag to specify that the member variable is an array of SomeObjs? @var array is not enough, and @var array(SomeObj) doesn't seem to be valid, for example.

Answer 1

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[]
