PHP

As we all know, the PHP language, as a scripting language for server-side development, is very famous in website development. Since its creation by Rasmus Lerdorf in 1995, according to a W3Techs survey, PHP has accounted for 82% of known server-side programming languages. Among them are well-known technology companies such as WordPress and Facebook.

Advantage 1: Popular and easy to use

PHP is currently the most popular programming language, there is no doubt about it. It drives more than 200 million websites around the world, and more than 81.7% of the world's public websites use PHP on the server side. Not only that, according to statistics, 78.1% of people working in PHP believe that PHP is the easiest to learn and get started. This is because PHP's commonly used data structures are built-in, which is convenient and simple to use, not complicated at all, and its expression ability is quite flexible.

Josh Lockhart, a development engineer at NewMediaCampaigns, once said: PHP is the easiest website development language to learn. It can be installed on most servers, and due to the real-time updated documentation and Q&A, the PHP language is relatively Other languages ​​are simple and easy to learn.

Advantage 2: There are many development positions

In server-side website programming, PHP will more easily help you find a job. Many Internet-related companies such as JD.com, Taobao, Tmall, Google, Baidu, Sina, Tencent QQ, WeChat, etc. are using the PHP development framework, so it can be said that the market demand for PHP development programmers is still relatively large. Searching for PHP engineers through various recruitment websites, the numbers we got made our eyes light up. Zhaopin has 43,081 PHP recruitment positions; 51,008 recruitment positions; the relevant data from Liepin.com is 6,013. It can be seen that There are many demands for PHP, and there are many positions.

Advantage three: Still developing

PHP is constantly compatible with technologies such as closures and namespaces, while taking into account performance and currently popular frameworks. After version 7, it has been providing higher-performance applications. In some WordPress benchmark tests, the performance can reach 3 times that of PHP 5.6. PHP 7 includes some major security improvements, such as removing PHP safe mode, adding magic quotes, having some new reserved keywords, and more. In March this year, PHP 7.1.3 and 7.0.17 were officially released.

Java

The Java language has the following characteristics: simple, object-oriented, distributed, interpreted execution, robust, safe, architecture neutral, portable, high Performance, multithreading, and dynamics.

1. Object-oriented

The design of the Java language focuses on objects and their interfaces. It provides a simple class mechanism and a dynamic interface model. The object encapsulates its state variables and corresponding methods, achieving modularization and information hiding; while the class provides the prototype of a type of object, and through the inheritance mechanism, subclasses can use the methods provided by the parent class to achieve Code reuse.

2. Distribution

Java is a network-oriented language. The TCP/IP protocol can be processed through the class library it provides, and users can easily access other objects on the network through URL addresses.

3. Portability

The platform-independent feature allows Java programs to be easily transplanted to different machines on the network. At the same time, Java class libraries also implement interfaces with different platforms, making these class libraries portable. In addition, the Java compiler is implemented by the Java language, and the Java runtime system is implemented by standard C, which makes the Java system itself portable.

4. Security

Java used in network and distributed environments must prevent virus intrusion. Java does not support pointers. All access to memory must be achieved through the instance variables of the object. This prevents programmers from using deceptive means such as "Trojan" horses to access the private members of the object, and also avoids errors that easily occur in pointer operations. .

5. Interpretation and execution

The Java interpreter directly interprets and executes Java bytecode. The bytecode itself carries a lot of compile-time information, making the connection process simpler.

C

C language not only retains all the essence and characteristics of C language such as effectiveness, flexibility, ease of transplantation, etc., but also adds support for object-oriented programming. It has powerful programming functions that can easily construct entities and operations that simulate real-life problems; the programs written have excellent features such as clear structure and easy expansion, and are suitable for the programming of various application software and system software. Programs written in C have good readability, the generated code is of high quality, and the running efficiency is only 10% to 20% slower than assembly language.

Features:

C is a superset of C language. It not only maintains the simplicity, efficiency and closeness to assembly language of C language, but also overcomes the shortcomings of C language. Its compilation system can check more grammatical errors. Therefore, C language is safer than C language.

C maintains compatibility with the C language. Most C language programs can run directly in the C environment without modification, and many library functions written in C language can be used in C programs.

C programs have been improved over the C language in terms of reusability, scalability, maintainability and reliability, making them more suitable for developing large and medium-sized system software and applications.

C is designed to be a statically typed, multi-purpose programming language that is as efficient and portable as C.

C is designed to directly and extensively support a variety of programming styles (procedural programming, data abstraction, object-oriented programming, generic programming).

C is designed to give the programmer more choices, even if it may lead to the programmer making the wrong choice.

C is designed to be as compatible with C as possible, thereby providing a smooth transition from C to C.
