- Dynamically extract and sort WordPress ACF keywords and generate index links
- This article details how to programmatically use WordPress’ WP_Query and Advanced Custom Fields (ACF) plug-ins to extract the values of the specified ACF fields (such as "keywords") from the site-wide article. The tutorial will guide you how to collect links to these keywords and their corresponding articles and sort them alphabetically, and ultimately generate a clearly structured and clickable keyword index list, greatly improving the discoverability of website content and user navigation experience.

- Nested Ifs vs. The Match Expression: A Modern PHP Showdown
- For value-to-value mapping, match should be used first because its syntax is more concise, type-safe and performance is higher; 2. When complex logic, multivariate conditions or side effects are involved, nested if statements should still be used; 3. Match avoids type coercion through strict comparison and improves code predictability; 4. In high-performance scenarios, match is used to optimize jump tables internally, and the execution efficiency is better than long-chain if-else; 5. Final suggestions: use match for simple matching, use if for complex control flow, and select appropriate tools based on the scenario to achieve code readability and maintenance.

- Get the ACF field values of all articles in WordPress and generate an index list
- This article will introduce in detail how to programmatically obtain the values of specific ACF fields (such as keywords) in all articles and organize them into an alphabetical list, each keyword comes with a link to the article it belongs to, thereby creating a dynamic article keyword index. This method uses WP_Query to query articles, collects ACF field values and article links, and sorts and outputs them through PHP array functions.

- How to use the ON DUPLICATE KEY UPDATE statement in MySQL?
- ONDUPLICATEKEYUPDATE is used to handle unique key or primary key conflicts. 1. When there is duplication of insertion data, no error is reported but the specified field is updated; 2. Applicable to counters, data synchronization and other scenarios; 3. The syntax is INSERTINTO...VALUES...ONDUPLICATEKEYUPDATEcolumn=VALUES(column); 4. VALUES(column) obtains the value inserted in the original plan; 5. Only trigger updates when a unique key conflict occurs; 6. Each duplicate record is processed independently; 7. Pay attention to unexpected updates of AUTO_INCREMENT and TIMESTAMP columns; 8. It can avoid complex logic of checking first and then inserting.

- Unified file management and conditional execution policies for PHP front-end API interface
- This article discusses how to efficiently manage a PHP file so that it can be used as an API interface for front-end AJAX requests and as an internal library function for back-end PHP scripts. The core solution is to use the conditional judgment mechanism to distinguish HTTP requests from internal references, thereby avoiding unnecessary code execution and ensuring the flexibility and correctness of the script. The article will provide specific code examples and discuss related best practices.

- Best practices for PHP API assisted scripting: Taking into account the design and implementation of front-end AJAX and back-end PHP calls
- This article discusses in detail how to optimize PHP API assistive scripts so that they can efficiently serve front-end AJAX requests and back-end PHP internal calls at the same time. By introducing conditional execution logic, API processing is separated from function definitions to ensure that scripts behave consistently in different calling scenarios without side effects. The tutorial covers PHP file structure design, jQuery AJAX front-end call methods, and the back-end PHP's strategy of reusing code through include, aiming to improve the maintainability and reusability of the code.

- PHP file dual purpose: best practices for front-end API and back-end library
- This article will explore in-depth how to optimize PHP files so that they can serve as both an API interface for front-end AJAX requests and a function library that can be safely referenced by back-end PHP scripts. We will analyze common problems, such as accidental execution of complete logic when a file is included, and provide various strategies such as conditional judgment, modular design, and consistent parameter management to ensure the clearness, efficiency and maintainability of the code, while taking into account the different needs of front-end and back-end calls.

- The Definitive Guide to Mastering File Uploads with the $_FILES Superglobal
- The core of file upload is to verify errors, confirm file types, rename and safely move files. 1. First check whether $_FILES['error'] is UPLOAD_ERR_OK; 2. Use finfo to detect the real MIME type instead of trusting client data; 3. Verify file extensions and limit allowed types; 4. Rename files with random names such as bin2hex(random_bytes(16)) to prevent path traversal; 5. Move files from temporary directories to secure upload directories through move_uploaded_file(); 6. The storage location should be located outside the web root directory as much as possible, and if it needs to be disclosed, script execution will be disabled; 7. Use GD or
