  • LIGHTENING YOUR WORKLOAD WITH INCLUDES Introducing the PHP include commands PHP has four commands that can be used to include code from an external file, namely: • • • • include() include_once() require() require_once() They all do basically the same thing, so why have four? The fundamental difference is that include() attempts to continue processing a script, even if the external file is missing, whereas require() is used in the sense of mandatory: if the file is missing, the PHP engine stops processing and throws a fatal error.

  • Ernest Hemingway once offered a particularly sober assessment of his trade, saying, "There is nothing to writing. All you do is sit down at a typewriter and bleed." This being my fifth book, and the first published under my eponymous press, W.J. Gilmore LLC, I can sympathize with his appraisal. Thankfully, psychological first aid is readily available from the family, friends, and colleagues who always make this process much less painful.

  • This book will introduce you to one of the most important extensions to PHP that are available, starting with PHP version 5.0—the PHP Data Objects, commonly known as PDO. PHP grew in to a very popular web programming language due to its simplicity and ease of use. One of the key factors of this growing success is the built-in possibility to access many popular relational database management systems (RDBMS), such as MySQL, PostgreSQL, and SQLite, to name just a few.

  • CHAPTER 4 Expressions and Control Flow in PHP The previous chapter introduced several topics in passing that this chapter covers more fully, such as making choices (branching) and creating complex expressions. In the previous chapter, I wanted to focus on the most basic syntax and operations in PHP, but I couldn’t avoid touching on more advanced topics. Now I can fill in the background that you need to use these powerful PHP features properly. In this chapter, you will get a thorough grounding in how PHP programming works in practice and how to control the flow of the program.

  • Predefined constants PHP comes ready-made with dozens of predefined constants that you generally will be unlikely to use as a beginner to PHP. However, there are a few—known as the magic constants—that you will find useful. The names of the magic constants always have two underscores at the beginning and two at the end, so that you won’t accidentally try to name one of your own constants with a name that is already taken. They are detailed in Table 3-5. The concepts referred to in the table will be introduced in future chapters. Table 3-5.

  • My first experiments with object-oriented programming in PHP took place about six years ago. Unfortunately, the book that introduced me to the subject concentrated on the mechanics of writing classes and paid little heed to principles underlying OOP. As a result, I wrote classes that were closely intertwined with a specific project (“tightly coupled,” to use the OOP terminology). Everything worked exactly the way I wanted, but the design had a fundamental flaw: the classes couldn’t be used for any other project.

  • Anew year is upon us—and quite a few interesting things have already happened. We just published our first book, for example. The Zend PHP Certification Practice Test Book, which I co-wrote with John Coggeshall, has just been unleashed on the PHP community with (if I may unleash some personal pride) extremely good results. In a separate—but far more important— piece of news, PHP was named “language of the year 2004” by a site that tracks language usage in the development community.

  • While most editors will spend their first editorial explaining at length the arduous path the brought the fruit of their labor to life, I feel I have a higher goal to aspire to. Getting php|a off the ground has introduced us to some genuinely new experiences— nothing beats being awake at two o’clock in the morning (when you couldn’t read the lettering off a truck if it hit you) trying to pick a highly legible font that will work both on the screen and in print. Still, I don’t think you want to hear about that....
