Are the double underscores a WP thing or PHP thing or what? What do they mean?

(Also, on StackOverflow.)

Is it necessary to use __( ' string ' ) ???

2,092 PointsWell, it appears to be a "special" kind of naming a variable. Technically yes, you could probably just name your variable the conventional way. But why would you want to do it, if it is supportive of localisation. It looks heinous, sure, but it gets the job done just as well.
