How about if the option is used as a flag (i.e. without values)? php spark foo --sort
I think the value would be true or null? Not sure which one.

[kenjis]

null.

[kenjis]

Fixed.

[paulbalandan]

Ah yes. The true is when you use CLI::getOption() to get the value.

I noticed that PHPStan released 1.6.2 and it had a significant different set of detection where I was working on Myth:Auth - probably the same source here.

Thanks for the quick fix in the command types!
