The difference between php backend and java backend
The difference between php back-end development and java back-end development
1. Language comparison
PHP is a server script language that interprets and executes. First of all, PHP is simple and easy to use. The syntax is similar to that of C language, so programmers who have learned C language can quickly become familiar with PHP development. In Java, you need to first learn the syntax of Java, be familiar with some core class libraries, and understand object-oriented programming methods.
Java must first be compiled into a bytecode .class file, and then interpreted and executed on the java virtual machine. The first and easiest thing to think of in Java Web development is JSP (now JSP2.0). The original Java Web development was implemented with servlets. Development with servlets requires programmers to embed a large number of elements in the Java source files. html code.
So JSP appeared later. JSP can be easily embedded into html files. In fact, when the jsp file is executed on the server, it will first be converted into a servlet by the application server, and then compiled and executed.
Jsp can produce powerful functions through the support of servlets and JavaBeans. JavaBean is a reusable, cross-platform software component. Using javabean can easily realize the separation of java code and html, which can enhance the function of the system and the reusability of the software.
Web development in Java belongs to the J2EE specifications defined by SUN. And J2EE includes all aspects of Java's Web development, such as: JSP, Servlet, JDBC, JNDI, JAVABEAN, EJB, etc. J2EE is particularly suitable for large-scale enterprise-level applications.
2. Comparison of database access
Java accesses the database through JDBC and conveniently accesses the database through database drivers provided by different database vendors. The interface for accessing the database is relatively unified. PHP uses different database access interfaces for different databases, so the database access code is not very versatile. For example: a web application developed in Java only needs very few modifications to be transferred from a MySQL database to an Oracle database. PHP requires a lot of modification work.
3. Comparison of system design architecture
Web development technology using Java requires the use of object-oriented system design methods, while PHP still adopts process-oriented development method. Therefore, a lot of system analysis and design work needs to be done in the early stage of development using Java.
4. Cross-platform nature
Both Java and PHP have good cross-platform features. Almost all of them can run on different operating systems such as Linux or Windows without any modifications.
5. Development cost comparison
The most classic combination of PHP is: PHP MySQL Apache. It is very suitable for developing small and medium-sized Web applications, and the development speed is relatively fast. And all software is open source and free, which can reduce investment.
Java's Web application servers include free Tomcat, JBoss, etc. If you need better commercial services, they include: Web Sphere and Web logic.
6. Comparison of distributed multi-layer architecture
PHP can only implement a simple distributed two-tier or three-tier architecture, while JAVA is relatively powerful in this regard , can realize multi-layer network architecture. The 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. There is also the Spring framework in the business logic layer, and Hibernate and other frameworks in the database persistence layer. These frameworks can facilitate developers to construct multi-layer commercial applications efficiently, reasonably and scientifically.
7. Source code security
The source code of programs developed by PHP is public, and others can modify it after getting the program developed by PHP.
For programs developed in Java, what the user finally gets is just some compiled classes, and the complete source code cannot be seen, so the security is high.
8. Performance comparison
Some people have done experiments to do loop performance tests and Oracle database access tests for these two languages. In the loop performance test, JSP only took an astonishing four seconds to end the 20000*20000 loop. The PHP test was 2000*2000 loops (an order of magnitude less), but each took 63 seconds.
In the database test, the two performed 1000 Insert, Update, Select and Delete on Oracle 8 respectively: JSP took 13 seconds and PHP took 69 seconds.
To sum up:
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 developing large-scale application systems. The application prospects are relatively broad, the system is easy to maintain and has good reusability. Also, the price of a system developed with Java is higher than a system developed with PHP for the same function.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP remains important in modern web development, especially in content management and e-commerce platforms. 1) PHP has a rich ecosystem and strong framework support, such as Laravel and Symfony. 2) Performance optimization can be achieved through OPcache and Nginx. 3) PHP8.0 introduces JIT compiler to improve performance. 4) Cloud-native applications are deployed through Docker and Kubernetes to improve flexibility and scalability.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

PHP and Python each have their own advantages and are suitable for different scenarios. 1.PHP is suitable for web development and provides built-in web servers and rich function libraries. 2. Python is suitable for data science and machine learning, with concise syntax and a powerful standard library. When choosing, it should be decided based on project requirements.
