php needs to be installed to run: 1. Web server, commonly used ones include Apache, Nginx and Microsoft IIS; 2. PHP interpreter, which translates PHP code into executable machine code; 3. PHP extension, which can Provide additional functions and performance optimization; 4. Database, supports multiple databases, such as MySQL, PostgreSQL and Oracle; 5. PHP configuration file, used to manage runtime behavior; 6. Environment variables; 7. Text editor or integration Development environment; 8. Debugging tools.

PHP is a popular server-side scripting language used to create dynamic web pages and web applications. To run PHP code, the following components and settings need to be installed:

Web Server: PHP code must run on a web server. Commonly used web servers include Apache, Nginx and Microsoft IIS. Before installation, make sure the server is configured and running correctly.

PHP interpreter: PHP code needs to be executed through the PHP interpreter. The interpreter translates PHP code into executable machine code.

PHP extensions: PHP provides many built-in functions and features, but also supports adding functionality through extensions. Extensions are dynamic link libraries written in C that provide additional functionality and performance optimizations. Common PHP extensions include MySQL, GD image processing library, XML parser, etc. These extensions can be enabled in the php.ini file or loaded at runtime.

Database: Many web applications need to interact with databases. PHP supports a variety of databases, such as MySQL, PostgreSQL and Oracle. Before running PHP, you must first install and configure the required database server, and ensure that PHP and the database server can communicate correctly.

PHP configuration file: PHP uses a configuration file called php.ini to manage runtime behavior. This file contains many configurable options such as error reporting levels, memory limits, and upload file size limits. After installing PHP, you can modify the php.ini file as needed.

Environment variables: In order to run PHP scripts in the command line, you need to add the path of the PHP interpreter to the system's environment variables. This way you can use the "php" command directly from the command line to execute PHP scripts.

Text Editor or Integrated Development Environment (IDE): As a programmer, you need a tool for writing and editing PHP code. Commonly used editors include Notepad, Sublime Text and Visual Studio Code. If you need a more powerful development environment, you can consider using PHP-specific IDEs, such as PhpStorm and Eclipse.

Debugging tools: Debugging is an important part of the program development process. PHP provides some debugging tools, such as Xdebug and PHP Debug. These tools can help you locate and fix errors and problems in your code.

To summarize, to run PHP code, you need to install a web server, PHP interpreter, required extensions and databases, configure PHP and server-related settings, and use a text editor or IDE to write code. In addition, you also need to master some debugging skills and tools so that you can quickly locate and solve problems during the development process.
