This article will explain in detail the comparative analysis of java and php in web development. The content of the article is of high quality, so the editor shares it for you as a reference. I hope you will have some understanding of the relevant knowledge after reading this article.

Comparing the two web development technologies of php and jsp, the current situation is actually comparing the web development of php and java. Here are my comparisons on several main aspects:

I. language comparison

Php is a server scripting language that interprets and executes. First of all, php is simple and easy to use. The syntax is similar to the c language, so programmers who have learned the c language can quickly become familiar with php development. Java needs to learn the syntax of java and be familiar with some core class libraries and object-oriented programming methods. So java is not as easy to learn as php.

Java is first compiled into a bytecode .class file and then interpreted and executed on the java virtual machine. First of all, the easiest thing to think of in the web development of java is jsp (now jsp2.0). The original web development of java is realized by servlet, and using servlet to develop requires programmers to embed a lot of html code in the source files of java. So later, it appeared that jsp,jsp can be easily embedded in the html file, in fact, when the jsp file is executed on the server, it will first be converted into servlet by the application server, and then compiled and executed. Jsp can generate powerful functionality through the support of servlet and javabean. Javabean is a reusable, cross-platform software component. Using javabean can easily realize the separation of java code and html, and can enhance the function of the system and the reusability of the software.

The web development of java belongs to the specification of j2ee defined by sun. And all aspects of java's web development are included in j2ee, such as jsp, servlet, jdbc, jndi, javabean, ejb and so on. J2ee is especially suitable for large-scale enterprise applications.

II. Comparison of database access

Java accesses the database through jdbc and conveniently accesses the database through database drivers provided by different database manufacturers. The interface to access the database is relatively unified.

Php uses different database access interfaces for different databases, so the versatility of database access code is not strong. For example, web applications developed with java need only a few modifications to transfer from mysql database to oracle database. And php needs to do a lot of modification work.

III. Comparison of system design architecture

Using java's web development technology, we need to use the object-oriented system design method, while php still adopts the process-oriented development method. Therefore, a lot of system analysis and design work needs to be done in the early stage of development with java.

IV. Cross-platform

Both java and php have good cross-platform features. Almost all of them can be run on different operating systems such as linux or windows without any modification.

V. comparison of development costs

The most classic combination of php is: php + mysql + apache. Very suitable for the development of small and medium-sized web applications, the speed of development is relatively fast. And all the software is open source and free, which can reduce the investment.

Java's web application server has free tomcat, jboss, etc., if you need better commercial services are: web sphere and web logic.

VI. Comparison of distributed multi-tier architecture

Php can only implement a simple distributed two-tier or three-tier architecture, while java is more powerful in this respect and can achieve a multi-tier network architecture. Database layer (persistence layer), application (business) logic layer and presentation logic layer are separated from each other, and now different layers are supported by some mature development frameworks. For example, struts uses java's web development technology to implement the mvc design pattern, while there are spring frameworks in the business logic layer and hibernate frameworks in the database persistence layer. These frameworks can facilitate developers to construct multi-tier business applications efficiently, reasonably and scientifically.

Let's briefly talk about struts, which is essentially a mvc (model, view, controler) framework implemented on the basis of jsp model2. The jsp model2 architecture is a combination of jsp and servlet to provide dynamic content. In the struts framework, the model is composed of javabean or ejb components that implement business logic, the controller is implemented by servlet, and the view is composed of a set of jsp files. With struts, the definition of roles and the division of labor between developers and web designers can be clearly defined. And the more complex the project, the more obvious its advantages.

VII. Source code security

The source code of the program developed by php is public, and others can modify it after getting the program developed by php.

Java developed programs, * users only get some compiled class classes, can not see the complete source code, high security.

VIII. Performance comparison

Some people have done experiments to test the loop performance of these two languages and to access the oracle database.

In the loop performance test, jsp finished the 20, 000-20, 000 loop in an amazing four seconds. Php tested 2000 cycles (an order of magnitude less) in 63 seconds respectively.

In the database test, it takes 13 seconds for insert,update,select and delete for delete: jsp and 69 seconds for php for oracle 8, respectively.

Comparison of java and php in web Development

To sum up, I personally think that php is suitable for rapid development, small and medium-sized application systems, low development cost, and can respond quickly to changing needs. Java is suitable for the development of large-scale application system, the application prospect is broad, the system is easy to maintain and good reusability. Also, systems with the same functionality are more expensive to develop with java than those developed with php.

This is the end of the analysis on the comparison of java and php in web development. I hope the above content can be of some help and learn more knowledge. If you think the article is good, you can share it for more people to see.
