Violation of PHP function documentation specifications affects the usability of functions Impact

The PHP Function Documentation Specification is a set of guidelines that guide developers in writing clear and consistent function documentation. Although following these specifications is not strictly required, violating them may affect the usability and understandability of your functions.

Potential impact:

• Documentation is difficult to find: If the function documentation does not follow a standard format, it will be difficult to find it in the official documentation or PHP manual Find it in .
• Difficulty understanding: Obscure or insufficient function documentation can make it difficult to understand a function's functionality and usage.
• Incorrect usage: Inaccurate or incomplete documentation may lead to incorrect usage, such as passing parameters of the wrong type or in the wrong order.
• Debugging Difficulty: Tracking errors in functions that may be inconsistent with documentation can be time-consuming.

Practical case:

Consider the following example of a function document that does not follow the PHP function documentation specification:

/**
 * 返回一个学生的成绩
 *
 * @param array $student 学生信息
 * @return int 学生成绩
 */
function get_grade($student)

This document violates the following specification :

• The parameter name does not begin with a dollar sign ($).
• The return value has no specified type.
• The description of the function is missing.

As a result, this function documentation is difficult to find in the manual, difficult to understand, and may lead to code errors.

Best Practices:

Always follow the PHP Function Documentation Specifications to ensure that function documentation:

• is clear and informative, containing A high-level overview of function purpose and usage.
• List all parameters in order and specify their name, type and description.
• Specify the type and description of the return value.
• Contain examples or usage instructions.
