Is there a big difference between java and php?

The difference between java and php is quite big. Let me introduce to you some of the differences between java and php:

java application The scenarios are relatively wide, and there are relatively many people. PHP is mainly used for websites. If it is used to build websites, PHP development is faster.

1. PHP is suitable for rapid development, small and medium-sized application systems, low development costs, 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.

2. Comparing the technical architecture of the system, PHP can only realize a simple distributed two-layer or three-layer architecture, while JAVA is very powerful in this regard and can realize a multi-layer network architecture.

3. Comparison of database access. PHP uses different database access interfaces for different databases, so the database access code is not very versatile, while Java accesses the database through JDBC and uses databases provided by different database vendors. The driver can easily access the database, and the interface for accessing the database is relatively unified.

4. Comparison of the security of Java and PHP

In the face of Java, which is both open source and cross-platform, PHP has lost many advantages, especially in terms of code security. The 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. Coupled with the advantages of system architecture, PHP and Java are far apart in terms of security. If we have to compare the security of PHP and Java, if the same thief patronizes PHP, he will just use it and change it, take whatever he wants, and he will be so happy that he can just wave a pen and visit here. .

When you visit java, you will find that it is guarded by the police and equipped with an automatic alarm device, even if you break through many obstacles to enter the room. But I found that all the valuables were placed in the encrypted safe, and I could only look at it with dismay.

5. Technical comparison between Java and PHP

Java is a pure object-oriented development with powerful functions and many branches. There is no software that Java cannot do. 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.

Comparing the two, Java basically wins. But in fact there is not much comparability, because the areas of focus are different. Simply taking the WEB that can do both, PHP wins completely.
