php - What's the difference between 'false === $var' and '$var === false'?

Is one more readable than the other? At first, I disliked the false === approach but as I see it more and more often, I'm warming up to it. I'm pretty sure they return identical results.

There's absolutely no functional difference.

I usually prefer to place the variable first, and the constant value second. Because that makes sense (When you speak it out loud, would you say "I test that the variable is false"? Or "I test that false is equal to the variable"?)
