How do I follow coding standards (e.g., PSR-1, PSR-2) in PHP?
Jun 26, 2025 am 01:00 AMComplying with PSR-1 and PSR-2 standards is crucial for PHP project development. 1. Use code formatting tools such as PHP-CS-Fixer and PHP_CodeSniffer to automatically handle code style issues and integrate them into the IDE or CI process; 2. Follow the basic naming and structural rules in PSR-1, including the naming method using the correct PHP tags, class names and method names; 3. Follow the code structure details in PSR-2, such as controlling spaces after structural keywords, left curly braces and 4 space indentation; 4. Unify the encoding style in the project, ensure consistency through the .editorconfig file, and write the specifications to README or contribution guide to support team collaboration. These practices can improve the readability and maintenance of code, and the initial configuration is cumbersome but worth it.
sure! If you are developing a PHP project, it is very important to follow coding standards such as PSR-1 and PSR-2. It not only improves the readability of the code, but also facilitates collaboration among multiple people. Here are some practical suggestions to help you better understand and apply these standards.
Automatic processing using code formatting tools
It is not realistic to remember every PSR rule manually, especially details like indentation, spaces, and bracket positions. It is recommended to use tools such as PHP-CS-Fixer or PHP_CodeSniffer to automatically check and fix code format problems.
- PHP-CS-Fixer can automatically adjust the code style according to the configuration file.
- PHP_CodeSniffer is more inclined to detect whether it complies with a certain encoding specification and gives prompts.
You can integrate these tools into an IDE (such as PhpStorm or VS Code) to run automatically when saving files, or check them as part of the CI process before submitting the code.
Installation example:
composer requires friendsofphp/php-cs-fixer --dev
After configuring the .php_cs.dist
file, you can start using it.
Familiar with basic naming and structural rules
PSR-1 mainly stipulates some basic coding specifications, such as:
- PHP tags must use
<?php
and?>
(but if it is a pure PHP file, the end tag can be omitted) - Class names must be named by the big camel (for example,
MyClass
) - Method names are named by small camel (for example,
myMethod
)
PSR-2 extends the details of the code structure on this basis, such as:
- Control structure keywords (such as
if
,for
) should have spaces after them - The left braces
{
If you want to break the line, you cannot follow the same line as the function definition (note that this is often ignored) - Indentation uses 4 spaces, not Tab
These details may seem simple, but they are prone to errors in teamwork. It is best to match the IDE's code template settings to avoid manual adjustments every time.
Unify style and form habits in projects
Even for personal projects, it is recommended that you set the coding style to use from the beginning. You can add .editorconfig
files to the project root directory, so that different editors can remain consistent when opening.
Also, if you are working in a team, it is best to write the coding specifications into the project's README or contribution guide and attach the configuration file to ensure that everyone can easily access.
For example:
- All classes are placed in
src/
directory, and each class has a file - Namespaces are organized according to PSR-4 automatic loading
- Use a unified annotation format (such as docblock annotation functions and classes)
After persisting for a while, you will find that the code you wrote is not only cleaner, but also easier to maintain.
Basically that's it. It may feel a bit cumbersome at first, but once you configure the tools and develop a habit, it is actually not complicated, but there are many small details that are easy to be ignored.

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.

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.

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

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.

PHP ensures inventory deduction atomicity through database transactions and FORUPDATE row locks to prevent high concurrent overselling; 2. Multi-platform inventory consistency depends on centralized management and event-driven synchronization, combining API/Webhook notifications and message queues to ensure reliable data transmission; 3. The alarm mechanism should set low inventory, zero/negative inventory, unsalable sales, replenishment cycles and abnormal fluctuations strategies in different scenarios, and select DingTalk, SMS or Email Responsible Persons according to the urgency, and the alarm information must be complete and clear to achieve business adaptation and rapid response.

PHP does not directly perform AI image processing, but integrates through APIs, because it is good at web development rather than computing-intensive tasks. API integration can achieve professional division of labor, reduce costs, and improve efficiency; 2. Integrating key technologies include using Guzzle or cURL to send HTTP requests, JSON data encoding and decoding, API key security authentication, asynchronous queue processing time-consuming tasks, robust error handling and retry mechanism, image storage and display; 3. Common challenges include API cost out of control, uncontrollable generation results, poor user experience, security risks and difficult data management. The response strategies are setting user quotas and caches, providing propt guidance and multi-picture selection, asynchronous notifications and progress prompts, key environment variable storage and content audit, and cloud storage.

Select the appropriate AI voice recognition service and integrate PHPSDK; 2. Use PHP to call ffmpeg to convert recordings into API-required formats (such as wav); 3. Upload files to cloud storage and call API asynchronous recognition; 4. Analyze JSON results and organize text using NLP technology; 5. Generate Word or Markdown documents to complete the automation of meeting records. The entire process needs to ensure data encryption, access control and compliance to ensure privacy and security.
