COURSE INTRODUCTION i

Introduction

Zend Foundations of PHP Course--Objectives The Zend Foundations of PHP Course is designed to provide non-programmers with a solid foundation in the PHP language. This course guides you through the basics of PHP with an experiential approach, filled with numerous examples and hands-on exercises. By the end of the course, you will have coded key components to complete a functioning Blackjack program* while you learn the essentials you need to program in PHP. You will also have the opportunity to use the Zend Studio IDE (Integrated Development Environment) to start your coding adventures the easy and correct way!. It is also important to keep in mind what this course is not meant to do:

• You will not develop a full application “from scratch” because of time limitations – instead, you will focus on key aspects of the development process as they relate to developing basic programming skills.
• Not all development aspects will be covered in this course, as it is designed to teach basic programming concepts. * Ability to complete the application will depend on speed and ability of participant

Participant Requirements This course is designed for those who want to learn the basics of the PHP language, and assumes some familiarity with web sites – what they are and the very basics of how they work – but no programming experience. Web designers who want to become PHP Developers would certainly benefit from this course. This course could also be appropriate for those programmers who have very limited exposure to other languages, and want to now learn PHP. For those who have some PHP knowledge, you should review the description of our intermediate-level course, “Higher Structures of PHP” to see if that content would be more appropriate for your existant skills. For those who are experienced programmers in OO or procedural languages, we would suggest that you take the “Quick Start: PHP for Experienced Programmers” course. Please refer to the description of both either in our current catalog, or online at: www.zend.com.

• To computers, all instructions are ultimately on or off, 1 or 1, binary. Programming languages were developed to provide clear humanly-understandable instructions that are then compiled, interpreted or otherwise processed to create machine language instructions (in zeros and ones) that the computer uses.

• Client/server describes the relationship between two computer programs in which one program, the client, makes a service request from another program, the server, which fulfills the request. Client/Server is really only an important concept in a networked environment. Most business applications being written today use the client/server model, as well as the Internet's main program, TCP/IP.
• In the usual client/server model, one server, sometimes called a daemon , is activated and awaits client requests. Typically, multiple client programs share the services of a common server program. Both client programs and server programs are often part of a larger program or application.
• Relative to the Internet, your Web browser is a client program that requests services (the sending of Web pages or files) from a Web server (which technically is called a Hypertext Transport Protocol or HTTP server) in another computer somewhere on the Internet. Similarly, your computer with TCP/IP installed allows you to make client requests for files from File Transfer Protocol (FTP) servers in other computers on the Internet.
