auto-fix "Only booleans are allowed in an if condition" #316
Description
Feature request
when the native type of a property is known, we can auto-fix the "Only booleans are allowed in an if condition" phpstan-strict-error.
same is true for method-calls/function-calls etc. which have a native return-type.
I think this applies to any expression for which we know a non-union native type.
e.g.
class CoffeeBreak
{
private array $arr;
public function getDuration(): int {
if ($this->arr) {
}
}
}can get fixed to
class CoffeeBreak
{
private array $arr;
public function getDuration(): int {
if (count($this->arr) !== 0) {
}
}
}https://phpstan.org/r/5a9de50b-cc0c-47c9-81f8-fbe4d609ed4d
Did PHPStan help you today? Did it make you happy in any way?

I dunno if we should prefer
or a
!== []check.This could work for some union too. The one I saw a lot

I don't care much about which expression we use (as projects will run code style fixing on it most of the time).
As soon as the expression is stricter we fix the phpstan error - thats most important

Btw should be a feature request for the strict-rules repository no ?
