I find it curious that all the boolean comparison examples are done with typecasting.
I mean a strict comparison between 0 and FALSE shows up as FALSE (aka not the same). For the people who don't know what a strict comparison is: A normal comparison is == and ignores types. Eg. 0 == "0" returns TRUE. A strict comparison is === and compares types too. Eg. 0 === "0" returns FALSE because it compares an integer and a string.
To me this video seems a little likely to lead people astray to where they might end up thinking that 0 === FALSE would return TRUE.
Hampton is apparently not a part of TTH anymore but I still felt like I should point this out.

0 and FALSE aren't identical. 0 is a number and FALSE is a boolean value. 0 returns false. PHP castes 0 to false.

8,947 PointsEhhh, this wasn't meant as a question really but more as an addendum to the video itself.
If you read it again you'll see that I said 0 and FALSE aren't identical, that a strict comparison returns FALSE (not the same).
