   <title>Control Structures</title>

-   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.
