Yoda Conditions are a useful way to force the type of the comparison in dynamic languages, since the left-hand side usually gets to establish the type of the comparison when it could otherwise be ambiguous. $num = "5"; if(5 == $num) { ... } Even in statically-typed languages, you'll often have to cast a type, and Yoda Conditions make that more readable than a big Lispy pile of parentheses. if(1 == (int)dr["num"]) { ... } // already has two pair parens if(((int)dr["num"]) == 1) { ... } // too many parens Stateful mental parsing of deeply nested parentheses seems a bigger problem than some Anglocentric difficulty with determining if two things are equal.
