@toscho I was just converting the conditions to Yoda conditions in one of my plugins, and I was shocked to learn that in a few cases I had only been using one equals sign when comparing!

@bungeshea This cannot happen if you make it a habit to write always three ===, ie. run a strict comparison.

@toscho Is there ever a situation where you shouldn't run a strict comparison? I wasn't sure if using it all the time would mess up something.

@bungeshea Yes, look what WordPress does with pre_get_option_ . $option. :D
And in one of my plugins I am using -1 as an ID for a ghost user.
I am relying in weak comparisons in these cases.

@toscho So the 'default' comparison operator I should use is ===, not ==?

yes

But $_REQUEST values are either array or string, never integer, even if you want an integer.

That's what intval() is for
