Do you know the advantages of php?

PHP (foreign name: PHP: Hypertext Preprocessor, Chinese name: "Hypertext Preprocessor") is a general open source scripting language. The grammar absorbs the characteristics of C language, Java and Perl, which is convenient for learning and widely used. It is mainly suitable for the field of Web development. PHP's unique syntax mixes C, Java, Perl, and PHP's own syntax. It can execute dynamic web pages faster than CGI or Perl. Compared with other programming languages, dynamic pages made with PHP embed the program into the HTML (an application under the standard universal markup language) document for execution, and the execution efficiency is higher than that of completely generating HTML tags. CGI is much higher; PHP can also execute compiled code. Compilation can achieve encryption and optimize code running, making the code run faster.

Advantages of PHP

There are many benefits to using PHP. Of course, the known disadvantage is that PHP has no commercial support because it is an open source project, and the resulting slow execution speed (until PHP4). But PHP's mailing list is very useful and unless you're running a very popular site like Yahoo! or Amazon.com, you won't notice any difference in PHP's speed. At least I didn’t feel it! Okay, let's take a look at the advantages of PHP:
-Learning process
Unlike Java and Perl, you don't have to bury your head in more than 100 pages of documents and study hard to write a decent program. . As long as you understand some basic syntax and language features, you can start your PHP coding journey. If you encounter any trouble later during the coding process, you can read the relevant documents again.
PHP's syntax is the same as C, Perl, ASP or JSP. For those who are more familiar with one of the above languages, PHP is too simple. On the contrary, if you know more about PHP, then it will be easy for you to learn several other languages.
You only need 30 minutes to master all the core language features of PHP. You may already understand HTML very well, and you even know how to use editing and design software or manually to create a beautiful WEB site. Since PHP code can be easily added to your site, while you are designing and maintaining your site, you can easily add PHP to make your site more dynamic.
- Database connections
PHP can be compiled to have functions that connect to many databases. PHP and MySQL are an excellent combination right now. You can also write your own peripheral functions to access the database indirectly. In this way, when you change the database you use, you can easily change the coding to adapt to such changes. PHPLIB is the most commonly used series of base libraries that can provide general transaction needs.
- Scalability
As mentioned before, PHP has entered a period of rapid development. It may be difficult for a non-programmer to extend additional functionality to PHP, but it is not difficult for a PHP programmer.
- Object-oriented Programming
PHP provides classes and objects. Web-based programming work requires object-oriented programming skills. PHP supports constructors, extracted classes, etc.
- Scalability
Traditionally, the interaction of web pages is achieved through CGI. The scalability of CGI programs is not ideal because it opens a separate process for each running CGI program. The solution is to compile the interpreter of the language commonly used to write CGI programs into your web server (such as mod_perl, JSP). PHP can be installed this way, although few people are willing to install it CGI this way. Embedded PHP can be more scalable.
