Assigning the condition in a variable raises an error

[roukmoute]

Bug report

If I assign a condition in a variable or in a method, phpstan brings me up a false error, I think.

Code snippet that reproduces the problem

https://phpstan.org/r/488425af-8e61-453e-b327-1084560a8b3d

Expected output

https://phpstan.org/r/470bbfe6-0518-4ea2-ae05-68742135bae6

The only difference between theses two links is on line 54:

-if (!$case) {
+if (!$parent) {

@roukmoute After the latest commit in dev-master, PHPStan now reports different result with your code snippet:

@@ @@
-58: Cannot call method getData() on MyInterface|null.
+No errors
