In this article, we’ll walk through a step-by-step guide on how to write a method that takes two integers as arguments and returns their sum.

Step 1: Define the Method

To start, we need to define the method. In PHP, a method is a function that is defined inside a class. We’ll create a class called Math and define a method called sumOfTwoNumbers. We’ll specify that it takes two integer arguments:

class Math {
  public static function sumOfTwoNumbers($num1, $num2) {
    // code goes here
  }
}

Step 2: Add the Integers

Next, we need to add the two integers together. We can do this using the + operator:

class Math {
  public static function sumOfTwoNumbers($num1, $num2) {
    $sum = $num1 + $num2;
    return $sum;
  }
}

Step 3: Return the Sum

Finally, we need to return the sum. In PHP, we use the return keyword to return a value from a method:

class Math {
  public static function sumOfTwoNumbers($num1, $num2) {
    $sum = $num1 + $num2;
    return $sum;
  }
}
