Customize PHP function documentation to fit your needs

PHP Custom function documentation can be created through comment blocks, including summaries, parameters, return values ​​and examples, simplifying development: improving code readability and understandability. Reduce errors by specifying parameter types and return values. Use examples to enhance debugging capabilities. Speed ​​up development with auto-completion and error checking.

Customize PHP function documentation to simplify your development

Introduction

PHP function documentation is a valuable tool for understanding and using functions. By leveraging custom documentation, you can easily document, organize, and maintain your functions, significantly improving your development efficiency.

Create custom function documentation

To create custom function documentation in PHP, use the /** and */ comment Block:

/**
 * 求两个数的和
 *
 * @param int $num1 第一个数字
 * @param int $num2 第二个数字
 *
 * @return int 两个数字的和
 */
function add($num1, $num2) {
    return $num1 + $num2;
}

Document Content

Function documentation must contain the following key information:

• Summary: of the function A brief description.
• Parameters: List of all parameters accepted.
• Return value: Description of the value returned by the function.
• Example:Sample code of how to use the function.

Practical case

The following is a practical case using a custom function document to record the add function:

// 定义函数
/**
 * 求两个数的和
 *
 * @param int $num1 第一个数字
 * @param int $num2 第二个数字
 *
 * @return int 两个数字的和
 */
function add($num1, $num2) {
    return $num1 + $num2;
}

// 使用函数
$result = add(5, 10);
echo "5 + 10 = " . $result; // 输出：5 + 10 = 15

Advantages

Custom function documentation has the following advantages:

• Improve code readability: Clear documentation allows other developers to Easily understand your code.
• Reduce errors: By specifying the correct parameter types and return values, you can prevent parameter mismatches or incorrect return types.
• Enhanced Debugging: Use examples to make it easier to debug your code and identify problems.
• Speed ​​up development: When using IDE tools, custom documentation can provide code auto-completion and error checking, thereby speeding up development.
