Inspecting Watched Items
On this page:
PhpStorm helps inspect any variables or watches item in its own window. For example, if you need to examine several references in detail, you can open an inspection window for each of them. So doing, a separate window is created for each variable or watch reference and all of its child references.
The inspection windows are non-modal, and you can launch as many as of them required. All changes of the references are immediately reflected in the corresponding inspection windows.
