What are the benefits of following PHP function documentation conventions?

The benefits of writing conventions for PHP function documentation include improving code readability, using consistent format and syntax, and providing clear comments. Enhance maintainability, detailed annotations reduce guess work and improve maintenance efficiency. Promote code reuse. Clear documentation enables others to quickly understand and use functions, reducing duplication of work.

Benefits of PHP Function Documentation

PHP Function Documentation is a set of best practices designed to improve code Readability, maintainability and reusability. Adhering to these specifications can bring the following benefits:

Improving code readability:

• Use consistent format and syntax to make code easier to read and understand .
• Provide clear comments explaining the function's function, parameters, and return values.

Enhanced maintainability:

• Well-documented functions are easier to debug and maintain.
• Detailed comments can reduce the guesswork in code interpretation and improve maintenance efficiency.

Promote code reuse:

• Clear documentation enables other developers to quickly understand and use functions.
• Reduce duplication of work and improve development efficiency.

Practical case:

The following is an example of writing a function that follows the PHP function documentation specification:

/**
 * 计算两个数的平均值
 *
 * @param float $num1 第一个数
 * @param float $num2 第二个数
 * @return float 两个数的平均值
 */
function average(float $num1, float $num2): float
{
    return ($num1 + $num2) / 2;
}

By following this specification, the Functions are easy to understand, maintain, and reuse:

• Clear comments: Provide a clear description of the function's purpose, parameters, and return values.
• Consistent format: Comments follow a standardized format to improve readability.
• Complete documentation: Contains all the necessary information to enable other developers to use the function effectively.
