What are the seven principles of PHP code specifications?
The seven principles of PHP code specifications include consistency, readability, simplicity, reusability, testability, security and performance. Detailed introduction: 1. Consistency, the code should maintain consistency, that is, use the same naming convention, indentation style, code comments, etc. throughout the entire code base. This can make it easier for team members to understand and read the code, and reduce errors and confusion. Possibility; 2. Readability, the code should be easy to read and understand. In order to improve readability, you can use meaningful variable and function naming, avoid using overly complex expressions and nested structures, etc.
The operating system of this tutorial: Windows10 system, PHP version 8.1.3, DELL G3 computer.
In PHP development, it is very important to follow good coding standards, which can improve the readability, maintainability and scalability of the code. The following are the seven principles of PHP code specifications:
1. Consistency: The code should maintain consistency, that is, use the same naming convention, indentation style, code comments, etc. throughout the code base. This makes it easier for team members to understand and read the code, reducing the chance of errors and confusion.
2. Readability: Code should be easy to read and understand. To improve readability, you can use meaningful variable and function names, avoid using overly complex expressions and nested structures, and use spaces, indentations, and blank lines to organize your code.
3. Simplicity: The code should be kept as simple as possible. Concise code is easier to understand and maintain, and reduces the possibility of errors. Code simplicity can be achieved by avoiding redundant code, using appropriate abstractions and design patterns, and following the single responsibility principle.
4. Reusability: Code should be highly reusable, that is, it can be reused in different scenarios and projects. In order to improve the reusability of code, commonly used functions can be encapsulated into functions or classes and placed in independent files so that they can be referenced and called when needed.
5. Testability: Code should be easy to test. Testable code makes it easier to perform unit testing, integration testing, and automated testing, thereby improving the quality and stability of your code. To improve code testability, you can use the design principles of dependency injection, decoupling, and modularity.
6. Security: The code should have certain security to prevent malicious attacks and data leakage. In order to improve the security of the code, you can use filtering and validating user input, avoid directly executing user-submitted code, use secure encryption algorithms, etc.
7. Performance: The code should have certain performance optimization. Performance optimization can improve code execution efficiency and response speed, and improve user experience. In order to improve the performance of the code, you can use appropriate data structures and algorithms, avoid repeated calculations and database queries, use cache appropriately, etc.
It should be noted that the above principles are not absolute, and specific coding specifications may vary depending on project needs, team agreements, and personal preferences. Therefore, in actual development, it is recommended to discuss and negotiate with team members to formulate code specifications suitable for the team.
To sum up, the seven principles of PHP code specifications include consistency, readability, simplicity, reusability, testability, security and performance. Following these principles can improve the quality, maintainability, and scalability of your code. If you have any further questions please feel free to let me know.

How to use PHP to build social sharing functions PHP sharing interface integration practice
Jul 25, 2025 pm 08:51 PM
The core method of building social sharing functions in PHP is to dynamically generate sharing links that meet the requirements of each platform. 1. First get the current page or specified URL and article information; 2. Use urlencode to encode the parameters; 3. Splice and generate sharing links according to the protocols of each platform; 4. Display links on the front end for users to click and share; 5. Dynamically generate OG tags on the page to optimize sharing content display; 6. Be sure to escape user input to prevent XSS attacks. This method does not require complex authentication, has low maintenance costs, and is suitable for most content sharing needs.
PHP integrated AI intelligent picture recognition PHP visual content automatic labeling
Jul 25, 2025 pm 05:42 PM
The core idea of integrating AI visual understanding capabilities into PHP applications is to use the third-party AI visual service API, which is responsible for uploading images, sending requests, receiving and parsing JSON results, and storing tags into the database; 2. Automatic image tagging can significantly improve efficiency, enhance content searchability, optimize management and recommendation, and change visual content from "dead data" to "live data"; 3. Selecting AI services requires comprehensive judgments based on functional matching, accuracy, cost, ease of use, regional delay and data compliance, and it is recommended to start from general services such as Google CloudVision; 4. Common challenges include network timeout, key security, error processing, image format limitation, cost control, asynchronous processing requirements and AI recognition accuracy issues.
PHP creates a blog comment system to monetize PHP comment review and anti-brush strategy
Jul 25, 2025 pm 08:27 PM
1. Maximizing the commercial value of the comment system requires combining native advertising precise delivery, user paid value-added services (such as uploading pictures, top-up comments), influence incentive mechanism based on comment quality, and compliance anonymous data insight monetization; 2. The audit strategy should adopt a combination of pre-audit dynamic keyword filtering and user reporting mechanisms, supplemented by comment quality rating to achieve content hierarchical exposure; 3. Anti-brushing requires the construction of multi-layer defense: reCAPTCHAv3 sensorless verification, Honeypot honeypot field recognition robot, IP and timestamp frequency limit prevents watering, and content pattern recognition marks suspicious comments, and continuously iterate to deal with attacks.

Jul 25, 2025 pm 08:57 PM
To realize text error correction and syntax optimization with AI, you need to follow the following steps: 1. Select a suitable AI model or API, such as Baidu, Tencent API or open source NLP library; 2. Call the API through PHP's curl or Guzzle and process the return results; 3. Display error correction information in the application and allow users to choose whether to adopt it; 4. Use php-l and PHP_CodeSniffer for syntax detection and code optimization; 5. Continuously collect feedback and update the model or rules to improve the effect. When choosing AIAPI, focus on evaluating accuracy, response speed, price and support for PHP. Code optimization should follow PSR specifications, use cache reasonably, avoid circular queries, review code regularly, and use X
PHP calls AI intelligent voice assistant PHP voice interaction system construction
Jul 25, 2025 pm 08:45 PM
User voice input is captured and sent to the PHP backend through the MediaRecorder API of the front-end JavaScript; 2. PHP saves the audio as a temporary file and calls STTAPI (such as Google or Baidu voice recognition) to convert it into text; 3. PHP sends the text to an AI service (such as OpenAIGPT) to obtain intelligent reply; 4. PHP then calls TTSAPI (such as Baidu or Google voice synthesis) to convert the reply to a voice file; 5. PHP streams the voice file back to the front-end to play, completing interaction. The entire process is dominated by PHP to ensure seamless connection between all links.
