Bug report

When using array_splice, the count of an array is assumed to still be non-zero, although all items may have been consumed by ref.

Expected output

No error, as per https://3v4l.org/YoPBg you can very well see that it is not always false :)

Did PHPStan help you today? Did it make you happy in any way?

Definitely, I found some bugs in my code (and yours;)
