Documentation on how to create PHP functions

In PHP, functions are created by using the @ notation Documentation instructions. This symbol is followed by a magic method (similar to a method) that provides information about the function. The syntax is as follows:

/**
 * @param Type $param1 描述参数 1
 * @param Type $param2 描述参数 2
 * @return Type 描述返回值
 */
function functionName(): Type
{
    // 函数体
}

Practical case: Calculating the sum of two numbers

The following example demonstrates how to create documentation for a PHP function that calculates the sum of two numbers:

/**
 * 计算两个数字的和。
 *
 * @param number $num1 第一个数字
 * @param number $num2 第二个数字
 * @return number 和
 */
function addNumbers(int $num1, int $num2): int
{
    return $num1 + $num2;
}

Magic method list

Commonly used magic methods are:

• @param: Describe the parameters of the function.
• @return: Describes the return value of the function.
• @throws: Describes the exceptions that the function may throw.
• @since: Indicates the PHP version in which the function was introduced or changed.
• @deprecated: Mark functions that are no longer recommended.
