In this article, PHP editor Baicao will lead you to deeply explore the powerful functions and usage skills of PHPDoc, allowing you to easily control code documentation and improve development efficiency. Join us on the PHPDoc journey to make code documentation easier and more efficient!

Code documentation is crucial in software development because it provides important information about the structure, functionality, and intent of the code. PHPDoc is a powerful documentation tool for php code that enables you to add comments in a structured and readable way.

Benefits of PHPDoc

There are many benefits to using PHPDoc, including:

• Improve code readability: Comments provide a clear explanation of the purpose and structure of the code, making it easy to read and understand.
• Enhance maintainability: Structured documentation enables maintainers to quickly identify the logic and reasons behind code changes.
• Simplify collaboration: Comments make it easy for team members to understand each other’s code, promoting collaboration and knowledge sharing.
• Generate documentation: PHPDoc can generate documentation, such as the api reference and user manual, providing a comprehensive overview of the code.

Get started with PHPDoc

Using PHPDoc is very simple. Just add a comment above the line of code, ending with /** starts with */ like this:

/**
 * 计算两个数字的和。
 *
 * @param int $a 第一个数字
 * @param int $b 第二个数字
 * @return int 数字之和
 */
function add($a, $b) {
return $a + $b;
}

PHPDoc Tag

PHPDoc comments contain special keywords called tags that are used to provide structured information about specific information about the code. Some common tags include:

• @param: Specify the parameters of the function or method.
• @return: Specify the return value of the function or method.
• @var: Specify the type and description of the variable.
• @throws: Specify exceptions that may be thrown by a function or method.

Demo code

The following example shows how to use PHPDoc to annotate a simple PHP class:

/**
 * 表示一个学生。
 */
class Student {
/**
 * @var string 学生姓名
 */
public $name;

/**
 * @var int 学生年龄
 */
public $age;

/**
 * 构造一个新学生。
 *
 * @param string $name 学生姓名
 * @param int $age 学生年龄
 */
public function __construct($name, $age) {
$this->name = $name;
$this->age = $age;
}

/**
 * 获取学生姓名。
 *
 * @return string 学生姓名
 */
public function getName() {
return $this->name;
}

/**
 * 获取学生年龄。
 *
 * @return int 学生年龄
 */
public function getAge() {
return $this->age;
}
}

Generated documentation

Using PHPDoc comments, you can generate extensive documentation using third-party tools such as Doxygen or PhpDocumentor. These documents can include API references, user manuals, and code structure diagrams.
