         * {Description}
         * These words have special meaning in PHP. Some of them represent
         * things which look like functions, some look like constants, and so
         * on - but they're not, really: they are language constructs. You
         * cannot use any of the following words as constants, class names,
         * function or method names. Using them as variable names is generally
         * OK, but could lead to confusion.
