Is the PHP function documentation specification compatible with other documentation standards?

PHP function documentation is written in accordance with Javadoc, Sphinx and AsciiDoc standards, including function name, description, parameter information (type and description), return value type and meaning, etc. The example is as follows: /**Extract integer from string * Extracts the first occurrence of integer from the given string. *@param string $string String from which to extract the integer @return int The extracted integer, or null if not found*/function extract_integer ($string)

PHP function documentation writing specifications

Introduction

Writing clear and concise function documentation is critical to maintaining an efficient code base. PHP has its own convention for writing function documentation, which follows other common documentation standards to ensure consistency and readability.

Standards Compatibility

• Javadoc: PHP function documentation uses Javadoc style comments, which is a Java-based comment format standardized format.
• Sphinx: Sphinx is a Python tool for generating documentation, used by PHP to generate function reference documentation. Sphinx documentation follows the ReStructuredText (reST) format.
• AsciiDoc: AsciiDoc is a plain text-based markup language and a tool for generating documentation for PHP functions.

Function document structure

A complete PHP function document includes the following parts:

/**
 * 函数名
 *
 * 函数描述
 *
 * @param array $参数名 参数描述
 * @return array 返回值描述
 */

Practical case

The following is a sample function document:

/**
 * 从字符串中提取整数
 *
 * 从给定的字符串中提取第一个出现的整数。
 *
 * @param string $字符串 字符串，从中提取整数
 * @return int 提取的整数，如果未找到，则返回 null
 */
function extract_integer($字符串)
{
    // 使用正则表达式提取第一个整数
    $匹配 = [];
    if (preg_match('/\d+/', $字符串, $匹配)) {
        return (int) $匹配[0];
    }

    return null;
}

Tips for compliance

• Use complete sentences and grammatically correct language.
• Briefly but comprehensively describe the purpose of the function.
• Explicitly specify the type and description of each parameter.
• Specify the type and meaning of the return value.
• Use code blocks to differentiate between code examples and documentation text.
• Follow the naming convention of Javadoc or reST format.
