Compared with other programming languages, dynamic pages made with PHP embed programs into HTML documents for execution, and the execution efficiency is much higher than CGI that completely generates HTML tags; PHP can also execute compiled code, and the compilation can Achieve encryption and optimize code running, making the code run faster. PHP has very powerful functions. PHP can realize all CGI functions and supports almost all popular databases and operating systems. The most important thing is that PHP can be extended with C and C++!

Advantages:

1. Open source code: In fact, all PHP source code is available. 2. PHP is free. Compared with other technologies, PHP itself is free. 3. The speed of PHP: Program development is fast, running is fast, and the technology itself is learned quickly. Embedded in HTML: Because PHP can be embedded in HTML language, compared with other languages, it is simple to edit, highly practical, and more suitable for beginners. 4. Strong cross-platform capability: Since PHP is a script that runs on the server side, it can run under UNIX, LINUX, and WINDOWS. 5. High efficiency: PHP consumes relatively few system resources. 6. Image processing: Use PHP to dynamically create images. 7. Object-oriented: In php4 and php5, object-oriented aspects have been greatly improved. Now php can be used to develop large-scale commercial programs. 8. Professional focus: PHP mainly supports scripting languages, both of which are C-like languages.
