Today, I would like to share with you which better knowledge points php and Java learn first, detailed content and clear logic. I believe 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 learn about it.

1. Grammatical comparison between php and Java

Php is a server scripting language that interprets and executes. First of all, php is simple and easy to use. The syntax is similar to the c language, so programmers who have learned the c language can quickly become familiar with php development.

To learn java, you need to learn the syntax of java and be familiar with some core class libraries and object-oriented programming methods. So java is not as easy to learn as php.

2. Comparison of php and Java system architecture design.

PHP uses a process-oriented development approach to focus on the Internet. WEB domain php has a unique advantage, using php to develop web is the best choice.

The Web development technology of Java needs to use the object-oriented system design method. In a word, Java has powerful functions and many branches, and there is no software that java cannot do.

3. Comparison of database access speed between php and Java.

Php uses different database access interfaces for different databases, so the versatility of database access code is not strong. For example, Web applications developed with Java need only a few modifications to transfer from MySQL database to Oracle database. And php needs to do a lot of modification work.

Java accesses the database through JDBC and conveniently accesses the database through database drivers provided by different database manufacturers. The interface to access the database is relatively unified.

4. Comparison of source code security between php and Java.

The source code of programs developed by PHP is public.

Java development of the program, the end users get only some compiled class classes, high security.

5. Comparison of development cost between php and Java.

The most classic combination of PHP is: PHP + MySQL + Apache. Very suitable for the development of small and medium-sized Web applications, the speed of development is relatively fast. And all the software is open source and free, which can reduce the investment.

Java's Web application server has free Tomcat, JBoss, etc., if you need better commercial services are: Web Sphere and Web logic.

6. Performance comparison between php and Java

Some people have done experiments to test the loop performance of these two languages and to access the Oracle database. In the loop performance test, JSP finished 2000020000 of the loop in an astonishing four seconds. PHP tested 20002000 cycles (an order of magnitude less) in 63 seconds respectively. In the database test, it takes 13 seconds for Insert,Update,Select and Delete for Delete: JSP and 69 seconds for PHP for Oracle 8, respectively.

Summary:

7. Which is better, php or Java?

From the above comparison, php and Java can be said to have their own advantages. Php is more suitable for rapid development, small and medium-sized application systems, low development cost and easy to learn. Java is more suitable for the development of large-scale application system, the application prospect is broad, the system is easy to maintain and good reusability. Which one you want to learn depends entirely on what kind of development you are more inclined to do in the future.

These are all the contents of the article "which is better to learn php or Java first". Thank you for reading! I believe you will gain a lot after reading this article.
