PHPDoc Hints for Arrays of Objects

PHPDoc provides an efficient way to specify variable types through its @var tag. However, extending this functionality to signify arrays of objects can pose challenges. This article explores potential solutions to hint PHPDoc for arrays of objects.

One possible approach within PhpStorm is to utilize the syntax @var SomeObj[]. For instance:

/** @var SomeObj[] */
private $someObjInstance;

Alternatively, the official PHPDoc documentation recommends specifying the element type within angle brackets:

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

By utilizing either of these methods, IDEs can effectively recognize and provide accurate insights for arrays containing specific object types, greatly enhancing the development process.
