This example is to let everyone know how to define a method in php and how to call it

The following defines a method, which is very simple, that is, to deal with the addition problem of 2 numbers
function add($number1, $number2) {

      $sum = $number1 + $number2;
      echo $sum;
}

Let's call the add() method
add(1,2);

/**
Note:
function is the keyword that declares the method. The add after this keyword is the name of the method, and the parameters are in parentheses.
It can also be without parameters. In brackets is the method. Inside is the logic of the method.

The following add(1,2) is the call to add. If there is no call, the method will not be executed.

*/

Define a method with a return value

function re($n1, $n2) {

      $sum = $n1 + $n2;

      return $sum;
}

Call a method with a return value, call this method, the value is 5.
echo re(2,3);
?>
