How to unicycle

I think I can officially say that I can ride a unicycle. I have been practicing on a unicycle for a couple weeks here and there. I finally got to the point where I can ride comfortably for a while.

Use bin2hex and unhex as simple sql injection prevention

When it comes to sql injection prevention prepared statement is definitely the correct solution but if you find yourself in a predicament that prevents you from using one hexing and unhexing works.

Use a query like this:
$query = "SELECT * FROM table WHERE column = UNHEX(".bin2hex($userInput).")";
