The key to writing PHP comments is to clarify the purpose and specifications. Comments should explain "why" rather than "what was done", avoiding redundancy or too simplicity. 1. Use a unified format, such as docblock (/*/) for class and method descriptions to improve readability and tool compatibility; 2. Emphasize the reasons behind the logic, such as why JS jumps need to be output manually; 3. Add an overview description before complex code, describe the process in steps, and help understand the overall idea; 4. Use TODO and FIXME rationally to mark to-do items and problems to facilitate subsequent tracking and collaboration. Good annotations can reduce communication costs and improve code maintenance efficiency.

The first step is to select the integrated environment package XAMPP or MAMP to build a local server; the second step is to select the appropriate PHP version according to the project needs and configure multiple version switching; the third step is to select VSCode or PhpStorm as the editor and debug with Xdebug; in addition, you need to install Composer, PHP_CodeSniffer, PHPUnit and other tools to assist in development.

PHP comparison operators need to pay attention to type conversion issues. 1. Use == to compare values only, and type conversion will be performed, such as 1=="1" is true; 2. Use === to require the same value as the type, such as 1==="1" is false; 3. Size comparison can be used on values and strings, such as "apple"

There are three common ways to use PHP comments: single-line comments are suitable for briefly explaining code logic, such as // or # for the explanation of the current line; multi-line comments /*...*/ are suitable for detailed description of the functions or classes; document comments DocBlock start with /** to provide prompt information for the IDE. When using it, you should avoid nonsense, keep updating synchronously, and do not use comments to block codes for a long time.

The core of audio and video processing lies in understanding the basic process and optimization methods. 1. The basic process includes acquisition, encoding, transmission, decoding and playback, and each link has technical difficulties; 2. Common problems such as audio and video aberration, lag delay, sound noise, blurred picture, etc. can be solved through synchronous adjustment, coding optimization, noise reduction module, parameter adjustment, etc.; 3. It is recommended to use FFmpeg, OpenCV, WebRTC, GStreamer and other tools to achieve functions; 4. In terms of performance management, we should pay attention to hardware acceleration, reasonable setting of resolution frame rates, control concurrency and memory leakage problems. Mastering these key points will help improve development efficiency and user experience.

Writing PHP block annotations can improve the readability and maintenance of the code. It should include information such as @param, @return, @throws, etc., and explain "why" and "how to use", avoid meaningless repetition, keep updating synchronously with the code, and the IDE can automatically recognize prompts.

Writing good comments is crucial to teamwork, especially in PHP projects, the key is how to write useful comments. 1. Use DocBlock to clarify the purpose of the function, including parameters and return value types, and improve IDE recognition and development efficiency; 2. Add in-line comments to complex logic to explain key judgment conditions or special processing; 3. Unify the annotation style, standardize the format and content requirements, and use the tool to check to ensure consistency.
