Introduction
Any PHP script is built out of a series of statements. A statement can be an assignment, a function call, a loop, a conditional statement or even a statement that does nothing (an empty statement). Statements usually end with a semicolon. In addition, statements can be grouped into a statement-group by encapsulating a group of statements with curly braces. A statement-group is a statement by itself as well. The various statement types are described in this chapter.

Statements "usually" end with a semicolon. In particular, statements that are statement-groups end with the "}", and a closing "?>" is also enough to end a statement (and turn off parsing, of course).
Writing "};" is wrong and can lead to bugs because now there's one of those "empty" statements in there that could potentially mess with control flow.
