PHP 4 complete Chinese manual preface

Playing webmaster's role has been six years, from the early CERN and NCSA servers, later Netscape Enterprise server, to the present Eminence Apache, the face of the development of CGI program, always have the feeling of less effort. The most impressive thing is that on WindowsNT IIS, using Delphi, invoking ISAPI and OLE to connect to SQL Server, that was a painful day.

And the network has been unknown a few times, a single browser from the Moasic/lynx, to Netscape alone, and finally by Internet Explorer to become a new hegemony, after the new 21st century, Linux and Open Source (including Mozil LA) will also shake Microsoft's empire. In the face of changes in the network every day, webmaster to write the program, and then embed the visual screen, and finally compile the program, configure the system environment, the result is not easy to debug. Believe that the only hope is not only the ODBC features of the ASP, but belong to the open group of PHP.

Facing the internet,php should be the basic ability that the website worker needs to have, otherwise will quickly be brushed down by the Internet torrent. Whether it's a personal website, an E-commerce site, or even a large portal or a small group site, PHP has a lot of success stories. Some of the domestic system software companies are also starting to support PHP, such as Dbmaker is the best example.

After the advent of the PHP3, the idea of acting as a missionary to liberate all webmaster was raised, as did the notion of free documentation. Knowledge should be presented in a variety of ways, whether it be a virtual Web page, a traditional book, or a new generation of portable e-books. I am very pleased to meet the same concept of Dimou International publishing house Lee, and strongly support this idea, so there is a book. At the same time also get biglobe old colleagues support, so there is such a website http://php.wilson.gs.

Strictly speaking, this book is not very suitable for the novice network workers, especially if you do not understand HTTP and HTML, it may be more difficult. But the world is not difficult, I believe that as long as the full input, in a few months, can be from the network of recruits to become professional veteran. For other CGI experience (such as Prel, C, Python, Java, etc.) of the senior network workers, this book should allow you to the shortest possible time, the most powerful tool to operate, so that your productivity greatly increased. Even if you are a Microsoft lover, this book will allow you to jump from ASP to fully functional PHP.

PHP BIBLE around for about 10 months, knocking almost every day until three o'clock in the morning. Often think, open Source and open Group is really in addition to fanatics, not normal people can do, even the PHP original Rasmus Lerdorf all want to before marriage, ask netizens send postcards to his fiancee, it is not only Rasmus Lerdorf their own fanaticism.

Of course, I should thank my parents, sleep every day to endure my English typewriter to practice the keyboard sound to three points; like other computer fanatics, and dating girlfriends for many years of time, in fact, I do not spend time with the computer one-tenth, alas, really sorry.

Guide

Chapter two
Chapter three
Fourth chapter

For those who have just started to contact PHP, it is advisable to start with the first chapter or chapter two, and lay a good foundation. For readers with a certain base, it is advisable to look at the fourth chapter and study ready-made programs to deepen your impression of PHP's grammatical structure.

PHP the ins and outs

It's interesting to talk about the full name of PHP, which is a recursive abbreviated name, "Php:hypertext preprocessor", and open abbreviations or abbreviations. PHP is an HTML-embedded language (similar to an ASP on IIS). PHP's unique syntax blends the new syntax of C, Java, Perl, and PHP. It can execute dynamic Web pages faster than CGI or Perl.

PHP was originally planned in 1994 A.D. Rasmus Lerdorf. In 1995, Personal home Page tools (PHP tools) began publishing the first release. In this early version, it provides simple features such as guest message book, visitor counter, etc. Then after the new members joined the development ranks, in 1995 years, the second edition of PHP asked the city. The second edition is named PHP/FI (Form interpreter). Php/fi and joined the mSQL support, since this has laid the influence of PHP in Dynamic web development. At the end of 1996, there were 15,000 Web sites using Php/fi, and in 1997 years the Web site using PHP/FI grew to over 50,000. In 1997, the third edition of the development Plan was launched, and the development team joined the Zeev Suraski and Andi Gutmans, and the third edition was named PHP3.

PHP3 with the Apache server, coupled with its constant updating and adding new functionality, and it almost supports all mainstream and Non-mainstream databases, and its high-speed execution efficiency, so that PHP in 1999 years of use of the site more than 150,000!! Its source code completely open, in the open source consciousness rise today, it is the mainstay of this area. There are new functions to add to the library, as well as constant updates, so PHP can have more new features on either UNIX or WIN32 platforms. It provides a wealth of functions that allow for better support in program design.

PHP's fourth generation Zend core engine has entered the testing phase. The core of the entire script program is drastically altered to allow the program to execute faster and meet quicker requirements. Efficiency after optimization, has been more than traditional CGI or ASP and other programs have better performance. And there are stronger new features, richer libraries of functions. Whether you accept it or not, PHP will revolutionize the world of Web CGI. It will also be one of the required courses for a dedicated Web Master.
