How to Declare PHPDoc Type Hints for Arrays of Objects in PHP?

Declaring PHPDoc Type Hints for Arrays of Objects

When using PHPDoc to hint the type of member variables, you can specify @var followed by the desired type, such as @var SomeObj. However, you might encounter challenges when attempting to indicate that a member variable is an array of objects.

To address this, PhpStorm (IDE from JetBrains) provides a solution by allowing you to use / @var SomeObj[] / syntax. For instance:

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

Alternatively, the phpdoc documentation suggests using the following approach:

/**
 * @return array<int>
 */
function getArrayOfIntegers() {...}

Here, the specified type, , indicates the expected type of each array element.
