Advantages and disadvantages of PHP

Advantages:

1. Quick to get started, there are others Programmers with basic language skills can get started in about two weeks, and can basically develop simple projects in about a month.

2. Low development cost, the most classic combination of PHP is: Linux Apache MySQL PHP. It is very suitable for developing small and medium-sized web applications. Because it is easy to get started, the development speed is relatively fast. And all software is open source and free, which can reduce investment.

3. PHP is an interpreted scripting language. You can execute the code after writing it. Unlike c, java, c and other languages ​​that need to be compiled and executed, it is relatively time-saving.

4. Relatively speaking, the average salary of PHP programmers is lower than the average salary of c, c, java programmers, especially for small and medium-sized enterprises, which can save some costs.

5. Configuration and deployment are relatively simple. Compared with JAVA development, the configuration of JAVA development is much more complicated. Many places such as Structs, Spring, Hibernate, Tomcat, etc. need to be configured, even when you are in the program Every SQL statement written needs to be configured in Hibernate first. Sometimes redeploying a class file or jar file may also require restarting the web server (Tomcat or Resin or other web servers) to make the newly deployed library file take effect.

PHP development mainly involves PHP's own configuration files and the configuration of the Web server (such as Apache or Nginx or Lighttpd, etc.), which are simpler than JAVA, and there is no need to restart after newly modified files. Web can take effect immediately.

6. There are many open source frameworks or open source systems that can be used. For example, the well-known open source frameworks include Zend Framework, CakePHP, CodeIgniter, symfony, etc., open source forums include Discuz!, Phpwind, etc., and the open source blog WordPress, Open source online store systems such as Ecshop, ShopEx, etc.

Disadvantages:

1. The multi-threading support is not very good. Most of the time we can only implement it through simple simulation, Via.

2. The object-oriented support is not very good. Relatively speaking, PHP5's object-oriented has been improved a lot.

3. The coding standards are not uniform. For example, to delete a user, some people use delete_user, while others may use deleteUser. If the coding standards are not formulated in advance, this situation may happen frequently, because everyone Everyone has their own coding habits.

4. The syntax is not very strict. For example, variables can be used without being defined. In c, java, and c, variables must be defined before they can be used.

Personally, I don’t think languages ​​are good or bad, it’s just that different languages ​​are used in different places and at different levels. The bottleneck in high-concurrency, high-performance web applications is often not the development language, but the most important thing is the architecture.
