Comparison between PHP, JAVA, and NET development languages

PHP: PHP was produced in 1994. Its syntax is a mixture of C, Java, Perl and some of his own programming syntax; PHP is embedded in HTML and executed; it is also an interpreted language. The early PHP was not a completely object-oriented programming language. It was only in versions after PHP 4 that object-oriented concepts began to be introduced.

JAVA: JAVA was produced in 1995. The JAVA language and JAVA platform are collectively called JAVA; its syntax is very close to the C language and C++ language, and JAVA is an object-oriented programming language. , JAVA is a compiled language. You can first compile the JAVA source code into a .class file and then interpret and execute it on the JAVA virtual machine.

.NET: In .NET, multiple programming languages ​​support development such as: VB, C#, F#, etc. Usually we are using C# for programming. C# is The .NET platform is a programming language specifically created in 2000. Its language syntax is similar to JAVA, C, and C++, and it is also an object-oriented programming language. C# also needs to be compiled into a .dll file, which is then compiled and executed by the CLR in the .net framework.

Language distinction: The biggest difference between PHP, JAVA, and C# is the execution method. There are also some differences in the language itself, such as whether it is strongly typed, whether it can be dynamically compiled, whether it is multi-threaded, whether it is distributed, whether it can move values, etc. As for the performance issues that many people talk about, I think there is not much difference in the performance issues of the language itself. The key lies in how the programmer writes the code. In addition, there are certain differences in the database combined with the language. PHP usually uses MySQL database, JAVA usually uses MySQL or Oracle, and C#, because it is a product of Microsoft, usually uses Microsoft-related databases such as Sql Server or Access. Sometimes Sqllite database is also used.

Platform:

PHP: When most people call PHP, there is no distinction between platform and language. We often only use PHP for WEB application development. As for the development of desktop applications, it seems that PHP has developed this kind of development platform in recent years, but it is almost impossible to see it in real applications. But it has to be said that PHP performs very well in WEB presentation layer applications, and has good advantages in terms of handling interface layout and performance.

JAVA: When we call JAVA, we often don’t necessarily mean the language itself, but the JAVA platform. In the JAVA platform, you can use the JAVA language to develop various applications, such as: Java SE, Java EE and Java ME, which are used to develop JAVA desktop applications, WEB applications, mobile applications, etc. respectively.

.NET: In the .NET system, there is a clear distinction between language and platform, and multiple languages ​​can be developed on one platform, which satisfies those who master different languages. Programmers can develop the same application. In the .NET platform, like JAVA, different applications can be developed, such as: WinForm (desktop application), console application, ASP.NET (WEB application), WPF (new desktop application), WCF (network communication foundation Applications), WEB services (service-oriented programming applications), ASP.NET MVC3.0 (new WEB applications), XNA (desktop and mobile game applications), etc.

Platform distinction: All three technology platforms can be used for our commonly used WEB applications. For desktop applications, PHP is not very suitable, and JAVA does not have better development tools for desktop applications. In this regard, the .NET platform has better advantages. Both Winform and WPF are very suitable for desktop applications. As for implementing some underlying complex businesses, PHP is not as good as JAVA and .NET, but it has better advantages when doing the front-end presentation layer. Therefore, many complex large-scale comprehensive applications may have .NET or JAVA as the data access layer and business logic layer, and PHP as the presentation layer. It is said that Taobao was developed based on this method. At the same time, both JAVA and .NET (mono) can be cross-platform, and .NET can also be cross-language.
