Thankfully there are sites like php.net[1] that tell the truth: "null doesn't exist."

[1]: http://php.net/manual-lookup.php?pattern=null

The difference here is that null is a valid term in PHP. No comment about God objects.

mongodate => mon, god ate!

well, if people don't check for nulls they are just asking for trouble

I mean, you can always Google it, but that's personally what I read these comments for.
