What is the difference between website development languages ​​java and php? Which one is harder to learn, java or php? Should I choose self-study or training to learn PHP? This is a question asked by many students who want to work in the computer industry. The following article will introduce it to you. It has certain reference value. Friends in need can refer to it.

The difference between Java and PHP

1. 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.

2. Comparison of the development space of Java and PHP

Android has a strong momentum, but the number of installed apps on mobile phones is limited and promotion is difficult, which is also the biggest challenge facing apps. Good On Android, only JAVA can do it, and other than that it is HTML5. China's population accounts for 19.7% of the global population, Chinese Internet users account for 22.4% of the world's Internet users, and the number of Chinese websites accounts for 0.5% of the global number of websites. In developed countries, the Internet's contribution to GDP can reach 20%, while the impact of China's Internet on GDP is only 3%. It can be seen that the development space of the Internet is huge, and the Internet cannot be separated from WEB, and WEB cannot be separated from PHP. Compared with the two, I personally feel that PHP has more obvious advantages.

3. 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 in terms of code security. Especially prominent. 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.

Which one is harder to learn, Java or PHP?

In fact, all programming languages ​​do not have a clear distinction between difficult and not difficult. The so-called simplicity or not is all relative. Comparing Java with PHP, Java is more difficult to learn than PHP. PHP is recognized as a programming language that is relatively easy to learn. Generally, it takes about half a month of learning to develop a simple website, and generally it takes four or five days of learning to use PHP for secondary website development.

Among many programming languages, PHP is relatively easy to get started and is very suitable for novices to learn. Whether PHP is easy to learn or not depends entirely on whether you are good at learning it. When something goes wrong, first find the cause within yourself. This is an essential quality for programmers. The execution of the program will not be wrong, and bugs must be caused by the programmer's fault. PHP is the most widely used in the WEB field, and most small and medium-sized websites are built with PHP. It is not difficult to simply master PHP. The difficulty is that PHP programmers must understand the front-end, back-end, database, and server.

It is a bit difficult to become a PHP master. You need to write a lot of code and read a lot of code, which requires a lot of practical training. If you learn PHP by yourself, you will definitely not be able to find a direction, and your personal determination is not strong enough to persist. In the end, you will give up halfway and waste a lot of time! At this time, you need to find a reliable php training Institutional systematic learning, finding the right direction, and enhancing personal practical experience.
