- 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.

- What are the advantages and disadvantages of using a cloud-based PHP hosting platform?
- There are obvious advantages and disadvantages of choosing a cloud-based PHP hosting platform, and it needs to be weighed from four aspects: flexibility, cost, security and technical support. 1. High flexibility, supports elastic expansion and multiple configuration templates, but needs to be familiar with resource tuning; 2. The initial investment of the cost structure is low, suitable for small projects, but the long-term increase in costs may be due to additional services; 3. Security is guaranteed by the platform's basic protection, suitable for non-technical users, but insufficient support for highly customized needs; 4. Technical support is convenient and tools are easy to use, but excessive reliance on the platform may lead to migration difficulties.

- How to run PHP files in a browser?
- To run PHP files, you need to build a server environment first, because the browser cannot directly parse PHP. ① Install integrated environments such as XAMPP or WAMP, start Apache, place the .php file in http://localhost/yourfile.php, and access it through http://localhost/yourfile.php; ② Use PHP's own development server: enter the file directory on the command line and run php-Slocalhost:8000, and access http://localhost:8000/yourfile.php; ③ Pay attention to checking file path, spelling and permission issues to avoid 403 or 404 errors.

- What is the SOLID design principles, and how do they apply to PHP development?
- The application of SOLID principle in PHP includes five core points: 1. The single responsibility principle (SRP) requires each class to be responsible for only one task, and improve maintainability through separation functions such as UserService, UserRepository and EmailService; 2. The opening and closing principle (OCP) emphasizes extending openness, modifying closing, and using interfaces or abstract classes to implement new functions without changing old code. For example, the PaymentMethod interface supports multiple payment methods; 3. The Richter replacement principle (LSP) ensures that subclasses can replace parent classes without destroying logic, and avoid behavior abnormalities in the inheritance tree, such as Square should not inherit Rectangle; 4. The interface isolation principle (ISP) advocates dismantling

- PHP environment setup: database (MySQL/MariaDB) integration
- When building a PHP environment, the key steps for database integration are as follows: 1. Install MySQL or MariaDB and run a secure initialization script to set the root password, etc.; 2. Use PDO or mysqli to extend the connection to the database. It is recommended to enable pdo_mysql and restart the web server; 3. Write a test script to verify whether the connection is successful; 4. Troubleshoot common problems such as service running status, user permissions, remote access configuration, and PHP error logs. Follow these steps and check the details to ensure the database is successfully integrated into the development environment.

- PHP development environment setup: multi-version PHP switching method
- In response to the problem of switching environments of multiple versions of PHP, the following three solutions are recommended: 1. Linux/macOS uses PHPBrew, install the version and phpbrewinstall to switch the version, and configure environment variables; 2. Windows uses XAMPP with multiple PHP directories to modify the PHPIniDir in httpd.conf to point to the corresponding version and adjust the system PATH; 3. Use Docker across platforms, specify different PHP images in docker-compose.yml to achieve environmental isolation. The above methods are applicable to different operating systems and usage scenarios, and are simple to operate and can effectively improve development efficiency.
