Oracle Database 10g Express Edition PHP Web Programming

Chapter 5. Control Structures

This chapter examines how you define, declare, assign, compare, and process variables in conditional and iterative structures. It covers the following topics:

• Conditional structures

  • If statement

  • Switch statement

• Iterative control structures

  • Do-While loop

  • For loop

  • Foreach loop

  • While loop

By the end of this chapter, you will have completed your introduction to PHP and can begin writing larger and more complex programs.

While you now understand primitive variable definition and assignment, variables require conditional and iterative structures to become useful. This section will examine conditional structures and then iterative structures available in PHP.
