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.
