Which one is better, php or Java? Comparison of php and Java

The performance of Java and PHP have their own advantages and disadvantages. The differences are: 1. The syntax of PHP and Java is different; 2. PHP adopts a process-oriented development method, while Java is an object-oriented system design method; 3. , Java's interface for accessing the database is relatively unified; 4. PHP development speed is fast; 5. Java has high security.

Which one is better, php or Java? This question should be asked by many people, but each programming language has its own advantages and disadvantages. The so-called which one is better just depends on which one you are accustomed to using or which one you are better at, so today we Let’s talk about the comparison between php and Java.

1. Syntax comparison between php and Java

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.

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.

2. Comparison of PHP and Java system architecture design

PHP adopts a process-oriented development method and focuses on the Internet field. PHP has unique advantages in the WEB field, and using PHP to develop web is the best choice.

Java's Web development technology requires the use of object-oriented system design methods. In short, Java has powerful functions and many branches. 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 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.

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.

4. Comparison of PHP and Java source code security

The source code of programs developed by PHP is public.

For programs developed in Java, what the user finally gets is just some compiled classes, which is highly secure.

5. Comparison of PHP and Java 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. Performance comparison of PHP and Java

Some people have done experiments to conduct 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.

Summary:

Which one is better, PHP or Java?

Judging from the above comparison, PHP and Java can be said to have their own merits. 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 developing large-scale application systems. It has broad application prospects, easy maintenance and good reusability of the system. Which one you want to learn depends entirely on which aspect of development you are more inclined to do in the future.
