Undefined variable reported in empty

[JanTvrdik]

PHPStan incorrectly reports „Undefined variable: $a“

if (empty($a)) {

}

Yep, supporting empty() is on the roadmap, I discussed it today with @mzk.

In unset() included in this also?

// $set may or may not be empty.
foreach($set as $index => &$row) {
}
unset($row); // Undefined variable.

One solution I've seen is to put the unset() inside the foreach() loop.

I'll look into that.

unset is fixed (8ce4738), empty is still in the works.

Support for empty() is in 10eb46d.
