An operator is something that can produce another value (so that the entire structure becomes an expression) by giving one or more values (in programming jargon, expressions).

Operators can be grouped according to how many values they can accept. Unary operators can accept only one value, for example! (logic takes inverse operator) or + (increment operator). Binary operators can accept two values, such as the familiar arithmetic operators + (plus) and-(minus), as most PHP operators do. Finally, the only ternary operator?:, accepts three values; it is usually simply called the "ternary operator" (although it may be more appropriate to call it the conditional operator).
