I am the same as Salathe and a few others in this thread. However, touching on Village Idiot's point, I much prefer my variables to the left of the invariables.

As we typically read left from right, I like to see the variables and/or constants that are involved in the conditional immediately, instead of seeing the invariable, and then seeing what it's being checked against.

As Zend Framework is built by many programmers, I've noticed they use both ways in their framework code. I never thought of it as being a way to prevent accidental typos. It's always nice to have a new perspective on things !
