The point of being a good programmer is writting code that is easy to understand (comment your code when necessary!

), easy to maintain and with high efficiency, among other things.

Here is some example code - you can compare its output on x86 and x86_64 machines: The % operator doesn't behave as many people with a maths background would expect, when dealing with negative numbers.

For example, -1 mod 8 = 7, but in PHP, -1 % 8 = -1.Unary operators take only one value, for example , which takes three values; this is usually referred to simply as "the ternary operator" (although it could perhaps more properly be called the conditional operator).
