- How to configure the PHP runtime environment?
- The key to configuring the PHP operating environment is to select the appropriate version, match the web server and set the environment variables correctly. 1. Install PHP to select a stable version such as 8.1 or 8.2, and install common extensions such as php-mysql, php-curl, php-gd. Windows users need to manually modify the php.ini file to enable the extension, and Linux users generally enable it automatically; 2. Apache or Nginx can be selected with a web server. Apache needs to load the PHP module in the configuration file and specify PHPIniDir. Nginx uses PHP-FPM through FastCGI. Pay attention to the root and index.php settings. XAMP is available for local testing.

- PHP environment setup: Manual installation vs. integrated tools
- Newbie people are suitable for using integrated tools. Developers who have customization needs or want to have a deep understanding of the operating mechanism are more suitable for manual installation. Integrated tools (such as XAMPP, WAMP, MAMP or Laragon) package Apache, MySQL, PHP and other components, which are simple to install, convenient to start and stop services, and have adjusted the environment configuration, which is suitable for quick start and save time; while manual installation is suitable for situations where specific versions are required, expansion modules are enabled or customized configurations are enabled. Although there are many steps, you can fully control the details. The choice method must consider the purpose (learning basic development or project customization), the operating system (Laragon or XAMPP recommended by Windows, MAMP or Homebrew can be selected by Mac), and technical capabilities (if you are not familiar with the command line, you will first

- What is the difference between PHP 5, PHP 7, and PHP 8?
- The main differences between PHP5, 7, and 8 are reflected in performance, new features, compatibility and security. 1. In terms of performance, PHP7 rewrites ZendEngine 3.0 to make the speed about twice faster than PHP5. PHP8 introduces JIT compilation to further improve the performance of long-term operation and high-computing tasks; 2. In terms of new features, PHP7 adds scalar type declarations, return type declarations and spacecraft operators, and PHP8 adds joint types, named parameters, match expressions and attributes (notations); 3. In terms of compatibility and error handling, PHP7 removes the old deprecated functions, and PHP8 turns many fatal errors into catchable exceptions; 4. In terms of support and security, PHP5 has been stopped in 2018, and PHP7.4 will be 20.

- How do I use fibers for concurrent programming in PHP 8.1?
- PHP8.1's Fibers simplifies asynchronous programming through collaborative multitasking. Fibers are lightweight, stackless coroutines that allow manual pause and resume execution; they do not run in parallel and require manual scheduling; they are suitable for building custom concurrency models, especially suitable for I/O-intensive applications such as HTTP servers; when using them, you need to create Fiber objects and call the start or resume method; non-blocking I/O operations can be managed through integrated event loops; but it should be noted that they do not have real parallelism, exception propagation, limited ecosystem support, and experimental state.

- What are variable scopes in PHP (global, local, static)?
- There are three main scopes of variables in PHP: global, local and static. 1. Global scope refers to variables declared outside the function and can only be accessed outside the function. If it needs to be used inside the function, it must be introduced with the global keyword; 2. Local scope refers to variables declared inside the function, which are only valid inside the function, and the variables are destroyed after the function is executed; 3. Static scope is implemented through the static keyword, so that local variables retain their values ??between multiple function calls, but do not change their local access characteristics.

- How to run PHP on a virtual host?
- The following key points should be paid attention to when running PHP on a virtual host: 1. Upload PHP files to the correct directory, such as public_html or htdocs, and ensure that the file permissions are 644; 2. Check and select the appropriate PHP version to avoid version incompatibility issues; 3. If you use a database, you need to create a database and user in the control panel and modify the program configuration file to fill in the database information; 4. Pay attention to common problems, such as file path errors, disabled PHP functions, permission problems, and pseudo-static settings, etc., and enable error prompts if necessary to troubleshoot problems. As long as these steps are configured correctly, the PHP program will run smoothly.

- How to execute PHP scripts using the command line?
- To run the PHP command line script, you must first confirm that PHP has been installed and added to the environment variable path. Then you can execute the script through the php command. The specific steps are as follows: 1. Enter php-v in the terminal to verify the installation; 2. Use phpscript.php to execute the script; 3. The Linux/macOS system can add shebang and give execution permissions to run directly; 4. Pass parameters to the script through $argc and $argv. The entire process is simple and straightforward, suitable for automated tasks or testing.

- How to enable PHP error log?
- How to enable PHP error log? 1. Modify the php.ini file, set display_errors=Off, log_errors=On and specify the error_log path, and restart the web service to take effect; 2. Use .htaccess to enable logs, suitable for shared host users, configure php_flag and php_value to specify log paths and ensure that they are writable; 3. Temporarily enable it in the script, and set error log parameters through ini_set, which is suitable for debugging but not for long-term use. Pay attention to path permissions, configuration file differences in different modes, and log rotation issues.

- How to build a PHP runtime environment?
- To quickly build a stable PHP operating environment, pay attention to the following steps: 1. Install the PHP interpreter, use XAMPP/WAMP for Windows, use Homebrew for macOS, and use apt for Linux; 2. Use a web server, use mod_php or Nginx to cooperate with PHP-FPM for Apache; 3. Create info.php to test whether PHP is parsing normally; 4. Modify php.ini to enable display_errors, set error_reporting, adjust upload restrictions and time zones; 5. Optional Docker method to quickly build a standardized environment through docker-compose.yml. After each step is completed, the server should be restarted

- What are recursive functions in PHP?
- Recursive functions refer to self-call functions in PHP. The core elements are 1. Defining the termination conditions (base examples), 2. Decomposing the problem and calling itself recursively (recursive examples). It is suitable for dealing with hierarchical structures, disassembling duplicate subproblems, or improving code readability, such as calculating factorials, traversing directories, etc. However, it is necessary to pay attention to the risks of memory consumption and stack overflow. When writing, the exit conditions should be clarified, the basic examples should be gradually approached, the redundant parameters should be avoided, and small inputs should be tested. For example, when scanning a directory, the function encounters a subdirectory and calls itself recursively until all levels are traversed.
