- Solve the problem of failure to add WooCommerce booking products to the shopping cart programmatically
- This article explores the challenges encountered when adding a booked product to your cart programmatically in WooCommerce. Although booking records can be created successfully, adding bookings to carts using API methods often fails. The article analyzes the attempted API calls and their parameters, and proposes a "workaround" that simulates front-end form submission, but points out that the solution has session dependence and is not a stable and reliable programming solution. The final problem still needs to be solved in depth.

- PHP conditional output: gracefully omit the false value part of the ternary operator
- This article explores the tricks to implement conditional output in PHP, especially in scenarios where only the true value part needs to be output based on the condition without explicitly processing false values ??(i.e. outputting empty strings). By introducing a concise custom helper function, developers can avoid duplicate empty string parts in ternary operators, making the code more concise and readable, especially when embedding conditional outputs into complex strings.

- Limitations and standard methods for unfile execution of PHP code in Nginx FastCGI
- This article explores the feasibility of directly executing PHP code blocks in an Nginx FastCGI environment without saving them as files or creating symbolic links. The core conclusion is that Nginx's fastcgi_param directive is mainly used to pass environment variables rather than arbitrary code, and FastCGI interpreters such as PHP-FPM highly rely on the SCRIPT_FILENAME parameter to locate and execute scripts. Therefore, embedding and executing PHP code directly in Nginx configuration is not supported, and the standard practice is to specify a physical file path.
