Introduction to PHP language

The PHP development language is a fast, robust, free and rich development language with a large number of free library and development tools to use. PHP applies to any form and scale of the Web application system, as the most widely used development language on the Internet, PHP by many well-known commercial enterprises, government agencies and public welfare organizations welcome, including many of the most top-level portal, are based on the PHP system to build. A recent situation may show PHP's capabilities from a deeper level, as IBM relies on its acquisition of Eclipse Open source software to make itself a great source of Java development, with Oracle, the world's largest database vendor and platform-level application software provider, is constantly enhancing its support for PHP to strengthen its Web application strategy. The Oracle Web site can find a lot of learning materials about PHP, as well as specialized PHP columns, which demonstrate the maturity of PHP in the field of web development and even development prospects.

Complete cross-platform: Similar to JSP, PHP is a real cross-platform programming language that can run PHP applications well on any operating system with PHP interpreter. And more importantly, in almost all Linux operating systems and a large part of the UNIX operating system is installed by default all the software infrastructure required to run the PHP program, even including supporting the PHP application database capabilities.

Excellent execution performance: with Java,. NET and other popular web development technologies, PHP is more sophisticated and compact, and its ability to achieve a less. In fact, PHP employs a more "micro-kernel" implementation, which has its own streamlined and solid core architecture, while functional extensions rely on a variety of non-mandatory peripheral libraries. This gives PHP the biggest advantage of performing performance, and in the case of performing the same task, PHP is often able to get a better run than other Web development languages.

Adequate security: PHP is very rigorous design, and its long history of development experience a variety of tests, and has been continuously improved. Based on its open source features, a large number of professional software architects and software engineers around the world have been testing and testing their code to make it more secure and stable. Especially when working with the Apache server System, PHP can be integrated with Apache in a compiled way to provide a highly secure deployment environment.

Free: This is not a technical advantage, but for the implementation of the application function, a free but equally powerful platform, will inevitably bring a higher return on investment, but also often lead to greater project success possible. At the same time, after the selection of PHP can completely gain control of the developed system, not only for the system itself, the system relies on the operating environment is fully open, which can effectively avoid some future investment and commercial technical confidentiality restrictions.

With Microsoft's growing investment in enterprise-level development, NET is gradually becoming a very popular development platform, by comparing PHP and asp.net some features, you can more fully understand the characteristics of PHP. There are many grammatical similarities between the two, both of which use the syntax format of Class C, but PHP has some unique grammatical features, which is largely due to its more pure technical lineage, which makes PHP seem particularly fast and flexible in some areas. PHP is much more flexible than asp.net in developing databases. When connecting to Microsoft's own SQL Server, ASP. NET has unparalleled advantages. However, when connecting to other kinds of databases, PHP will be more comprehensive and stable, the vast majority of database systems provide PHP with good support and native interface programs, and these support is a large number of actual operating environment test. From the core language features, ASP. NET to be more complex, especially it can be with. NET platform is a good combination of the C # programming language, which enables complete object-oriented programming capabilities while accommodating some of the latest dynamic language programming features. Asp. NET's main disadvantage is that it can only run on Microsoft's operating system, which is still a big limitation for enterprise applications. Although there are some unofficial research projects that are going on. NET running environment is ported to open source operating systems such as Linux, but there is still a big gap between the availability of business levels. PHP at this point is completely no problem, almost any one of the operating system can host PHP environment, on the Microsoft operating system PHP can also be more efficient operation.
