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. The above is the detailed content of How to create documentation for PHP functions?. For more information, please follow other related articles on the PHP Chinese website!
