PR Summary

• Enhancements to the procedure of fetching child items within code loops
  The routine for fetching child items has been optimized for better performance, allowing for quicker process execution and efficiency.

• Introduction of array functionality for ItemsStorageInterface methods
  The methods getAllChildren(), getAllChildRoles(), and getAllChildPermissions() have been improved to accept an array of names, as opposed to just a single name previously. This gives flexibility and enhanced performance when retrieving multiple items.

• Refactoring code lines in Manager.php
  Here, we have replaced detailed code structures with more concise, readable expressions to improve code maintainability. It makes understanding and maintaining the code simpler, alongside optimizing for better performance.

• Code upgrades in FakeItemsStorage.php
  In line with the upgrades in ItemsStorageInterface, we also updated the parameters in getAllChildren(), getAllChildRoles(), and getAllChildPermissions() methods to accept an array of names. Furthermore, the internal getAllChildrenInternal() method was introduced to handle multiple name requests more efficiently.

These changes in totality focus on enhancing code performance, readability, and maintainability without altering the product functionality.
