PHP scripts: free-wheeling code is becoming more popular_PHP Tutorial

Remember those heady days when HTML evolved from version 1.0 to version 2.0, when mastering a new web language was as easy as looking at the code behind the website? Remember the easy way to learn basic HTML? Remember being able to randomly build some code and quickly see how it looks as you write it, and being able to easily modify the HTML code if it doesn't work? No IDE, no objects and classes. All it takes is a text editor, some markup, and your own ingenuity. It's fast and cost-effective!　　

　These days will not disappear forever. This "keep it simple" spirit continues in PHP, a scripting language that has become widely used in recent years. The language is constantly evolving and learning what PHP can and cannot do, and making web applications easier to build.

From unknown newcomer to star role on the Web

Like the Hollywood actors who entered the film industry in the early 1950s, PHP's true beginnings are not widely known. Some people think that PHP stands for "Personal Home Page." Some people believe that PHP is the acronym of its inventor. Actually, PHP stands for Hypertext Pre Processor and it was invented by a guy named Rasmus Lerdorf around 1994/95. Lerdorf proposed the PHP framework as a way to track how visitors to a Web site view their online resumes. He publicly released the original hypertext preprocessor source code to help other web developers perform similar operations with online content. 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　since then, Web developers, struck by the presentation features offered in HTML, began to see how beneficial this new PHP scripting language could be in building dynamic content Web sites. PHP code can be embedded directly into HTML code, and this young scripting language is as easy to master as HTML. 　　

　For developers, this means that they can quickly learn PHP, they can quickly build dynamic content Web sites, and code modifications can also be completed quickly. As developers program, they can see the results immediately, without the need for an IDE, and without having to worry about dealing with user types and integer types and objects and classes — which constitute the daily mental work developers need to worry about in more complex languages ​​like Java. . PHP keeps it simple in every way, and you don't have to be a skilled programmer to get started.
　

Due to PHP’s entry-level nature, an open source community has grown up around the language to help make PHP development easier. The language now supports several query protocols, has a robust transport protocol, and provides many different types of module libraries to help build PHP applications.

　
All these results show that the use of PHP has grown explosively in the last 3 years. Back in 2000, monitoring and consulting group Security Space Web Server reported that only 100,000 sites were using PHP. In August 2003, Security Space reported that the number of Web sites using PHP was nearly 1.4 million.



　
In June 2003, more than half (approximately 52%) of the web servers that participated in the Security Space survey There is some type of PHP running there. Because PHP is open source, it will undoubtedly have great appeal to other open source web products (such as the Apache web server, which grew up entirely with PHP). In Netcraft's most recent Domain Survey, Apache held more than two-thirds of the Web server market, while second-place Microsoft IIS had about 24 percent.
