Is it just me, or do other people feel like mysqli prepared statements like to never work the same way twice?

I just finished a 3 hour debugging session where the prepared statement just didn't work. Then, just moments ago, I commented out an "echo" that has nothing to do with the fucking statement! And guess what? It works.

one moment please, I need to let my anger out.

GAAAAAAAA YOU FUCKING STUPID COMPUTER! YOU SON OF A FUCKING BITCH!

and to the people who made mysqli...
I HATE YOUR FUCKING LANGUAGE SO MUCH RIGHT NOW!

*sigh*
Ok, I'm back.

Anyways,

I don't know how, but I think php can smell anger and loves to make life miserable.

Please tell me I'm not the only one.
