A lot of friends, struggle a problem, choose good PHP or Java Web development language? How to choose a suitable Web development language?

PHP and Java as two distinct application development language, both technical and development space, or market share proportion, has a different way of performance, the different ideas on the led to Java and PHP on Web application development shows the different results, to a certain world-wide, dig in PHP and Java which is better?

In short: PHP is an interpreted scripting language, grammar and language C are similar, easy to learn and easy to use, does not understand computer non-specialists after learning can also use PHP; And Java first compiled to Class files, and then in the Java virtual machine, Java development need to be familiar with Java syntax as well as some core architecture, so as to realize a reusable, cross-platform software, Java is more difficult than the PHP,

a, language is

PHP scripting language is interpreted server, first of all, PHP has the characteristics of simple and easy to use, grammar and c language is like, so learned c programmers can quickly familiar with PHP development, while the Java needs to learn Java syntax and familiar with some of the core class libraries, know the object-oriented program design method, so, in contrast, PHP better learn some,

Java first compiled into bytecode. Class files, and then to explain the execute Java virtual machine, Java Web development, first of all, is easy to think of is the JSP (now to JSP2.0), the original Java Web development is achieved with the servlet, the servlet you can use to develop need programmers in the Java source file embedded in a large number of HTML code, so then the JSP, JSP can be embedded into HTML file, in fact, the JSP file at the time of execution on the server will first be application server is converted into a servlet, then compile the execution, the JSP can be generated by JavaBean and servlet support powerful features, JavaBean is a reusable, cross-platform software components, using JavaBean can facilitate the implementation of the Java code and the separation of HTML, can enhance the function of system and software reusability,

Java Web development belongs to the SUN's definition of the J2EE specification, and in J2EE includes all aspects of Java Web development, such as JSP, Servlet, JDBC, JNDI, JAVABEAN, EJB, and so on, J2EE is particularly suitable for large enterprise applications,

2, technical architecture

Java is a pure object-oriented development, powerful, numerous branches, no Java software cannot do, C/S or B/S, tell from the function, no language can be compared with Java,

PHP is a rising star, has absorbed the Java and c and perl language advantage, focus on the Internet, the WEB domain PHP has advantaged advantage, no language can and his than WEB domain,

PHP has obvious advantage in comparison to the Java language, the use of Java is an object-oriented system design method, and PHP or USES process oriented development method, PHP can only implement simple distributed two layer or three layer architecture, and Java can realize multi-layer architecture, database layer (persistence layer), application logic layer (business), says logic layer separated from each other, and so now we have some different layers of mature development framework support, such as Struts is in using Java web development technology to realize the MVC design pattern, and have the Spring framework in business logic layer, database persistence layer such as Hibernate framework, the framework can facilitate developers efficient, reasonable and scientific architecture layers of business applications,

three, database access speed is

Java to access the database through JDBC, by different database vendors provide database driven and easily access the database, database access interface is unified,

PHP for different database in different database access interface, the general database access code is not so strong, for example: in Java Web application from the MySQL database to Oracle database needs to be done very little changes, and PHP is need to do a lot of modification work,

From mathematics and database access speed, the performance of Java is better than PHP, in fact, for cross-platform large enterprise application systems, Java has become almost the only option (Microsoft.net does not support cross-platform), but is that a Web site for application development, Java is in danger of being marginalized by PHP, almost all of the virtual host support PHP + MySQL, and the support of Java is few and far between, on the resources, there are countless PHP resources online, many famous large websites (such as Facebook, Mediawiki, etc.) are based on PHP, and only a few successful Java website,

Although Java maths and database access has the advantage, the architecture is quite perfect, but it can easily support PHP Web access, high strength can rapid application development, support PHP Web hosting a dime a dozen, makes a website using PHP development than using a Java development site is much faster, easier, and the advantages of Java have only suitable for traditional software project as the core of the development mode, and PHP is more suitable for take the customer as the core of the development of the SaaS model, therefore, PHP is completely in the advantage of Web site development that resulted because of the particularity of Web site development, is not a programming language feature,

4, development cost is

PHP classic combination is: PHP + MySQL + Apache, very suitable for the development of small and medium-sized Web application, the development speed is faster, and all of the software is free, open source can reduce investment,

Java Web application server has a free Tomcat, JBoss, etc., if you need a better commercial services: Web Sphere and Web logic,

5, the source code security

PHP development program's source code is open, others get a PHP development program can be modified after,

Java development program, the user is just some compiled class class, can't see the complete source code, high safety,

6, development space contrast

Momentum of android is meng, but limited phone installed app, promotion, is also a big challenge for the app, but is only JAVA android can do, in addition is the HTML 5,

With its population making up 19.7% of the world's population, China's netizens accounted for 22.4% of global Internet users in China website number accounts for 0.5% of the global number of websites, web site can be a huge development space; In developed countries the Internet's contribution to GDP is 20%, the influence of China's Internet to GDP is only 3%, is the development of the Internet space is huge, and the Internet without WEB , the WEB, so PHP is

Both, compared to individual PHP advantage is more obvious,

Above all, I personally think, PHP is suitable for rapid development, small and medium-sized application system, the development of low cost, easy to learn, able to make a quick response, what changes in demand in the debug, release, PHP also relatively simple Java,

And Java is suitable for the development of large application system, the prospect of application is broad, the system is easy to maintain, better reusability, Java's philosophy is "write once, run anywhere", Java under the application framework architecture is unparalleled, far more than any other language, Java framework conducive to large collaborative programming development, system maintenance, better reusability, and function of the same system with Java development than PHP development system price is to high,
