- 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.

- 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.
