Today, I would like to share with you the main differences between Java and PHP what are the relevant knowledge points, detailed content, clear logic, I believe that most people still know too much about this knowledge, so share this article for your reference, I hope you can get something after reading this article, let's take a look at it.

Get to know Java

Java is a computer programming language. Like C++, Python and other programming languages, Java is still widely used today. From our daily Android phone APP to most websites or management information system application server programs are written in the language Java. The reason why it is widely used is that it has a lot to do with the mainstream object-oriented programming idea of Java. The integration of data structure and its processing methods can reduce the amount of code, let programmers pay more attention to the design of the program, and increase the functionality of the program. At the same time, the concepts of pointer and multi-inheritance in class C language are reduced, and the concepts of multi-thread, distributed and embedded are introduced. With the use of virtual machine, Java becomes the best cross-platform language.

Get to know PHP

PHP, which stands for Hypertext Preprocessor, is a computer scripting language (Script languages). Scripting languages do not need to generate binary executables at compile time, as programming languages do, but execute directly on written PHP code to achieve the effect. Like the same scripting language JavaScript, PHP is also an interpretive language that can be directly interpreted and executed. PHP is not so much a programming language as a set of commands. We compare PHP with Java because it is also object-oriented and uses some variables from the programming language, but it is not as strict as the programming language. It is precisely because it is a group of commands that can be embedded in html to achieve web page special effects, so PHP is widely used in Web.

After fully understanding the two languages, the author makes a comparison from the aspects of system technical architecture and the prospect of Internet application.

System technical architecture

The idea of layering is a very important idea in the process of designing computer system. For example, the relationship among the common hardware layer, driver layer and application layer of the operating system. Delamination can better achieve the effect of high cohesion and low coupling. As we all know, Java language has a complete MVC framework, including view layer, business control layer and persistence layer. In the Spring framework, we can reduce the high coupling in the coding process through IOC and AOP, that is to say, these frameworks in Java can give developers a broader space to design scientific and reasonable architecture, which also reflects the characteristics of Java multi-tier architecture. Compared with Java, PHP does not leave much space for developers, but PHP is also improving in recent years to meet the needs of e-commerce and introduce MVC design pattern, but there is still a big gap between Java and Java in maturity and stability. It has to be mentioned that PHP is compatible with MySQL development, which makes PHP small and refined under the premise of considering cost factors, and has been favored by some small and medium-sized websites.

The Application Prospect of Internet

After accumulating a large number of developers and markets, Java has formed a complete ecology, so it is only natural for Java to enter the Web field. Although Java is often complained about in developing applications, Java has its own unique advantage in developing website systems is that JavaWeb achieves the unity of the front and back ends. For the sake of security, most enterprises use Linux server, and JavaWeb has good adaptability and portability to Linux, which is more convenient for the management of the front and back end of the website. At the same time, Java has rich design patterns, perfect framework and good stability in multithreading and high concurrency. Suitable for large-scale commercial projects. Of course, we should also see that PHP was born for the Internet from the date of its birth. Although it is not as complete as Java, PHP has the characteristics of small and sophisticated, and low deployment cost. PHP can also use distributed system, at the same time, it also provides more data interfaces to make up for its own shortcomings. In terms of Internet applications, how to choose needs to be combined with specific projects, considering costs and benefits as well as business needs.
