What is the difference between java and php

Java and PHP are both very widely used programming languages, and there are many differences between them. The following article will introduce to you the differences between java and php. I hope it will be helpful to you.

#1. Different areas of focus

Java is pure object-oriented development, with powerful functions and many branches. It cannot be done without Java software. C/S or B/S. Functionally speaking, no language can compare with Java. But its advantages are also its disadvantages. Please refer to the explanation of bottlenecks later for details.

PHP is a rising star, absorbing the advantages of Java, C, Perl and other languages, and focusing on the Internet field. In the WEB field, PHP has unique advantages. There is no language in the WEB field that can compare with PHP.

2. Differences in 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. Different system technical architecture

The Java language has a complete MVC framework, including the view layer, business control layer and persistence layer. In the Spring framework, we High coupling in the coding process can be reduced through IOC and AOP, which means that these frameworks in Java can give developers a broader space to design scientific and reasonable architectures, and also reflect the characteristics of Java's multi-layer architecture.

Compared with Java, PHP does not leave much space for developers. However, PHP has also been improved in recent years to cater to the needs of e-commerce and introduce the MVC design pattern, but in terms of maturity and stability There is still a big gap with Java. It must be mentioned that PHP is compatible with MySQL development, which makes PHP small and sophisticated while considering cost factors, and has been favored by some small and medium-sized websites.

4. Differences in security

In the face of Java, which is both open source and cross-platform, PHP has lost a lot of advantages, especially in terms of code security. .

php development program can be easily modified after others get the code. Programs developed in Java are more secure because they cannot see the complete source code and can only see some compiled class files.

5. Differences in development costs

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. The difficulty of learning is different

php is a server script language that interprets and executes. First of all, php has the characteristics of being 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.

To learn Java, you need to first learn Java syntax, be familiar with some core class libraries, and understand object-oriented programming methods. Therefore, Java is not as easy to learn as PHP.
