Error

Example 1

package main

import "fmt"
import "errors"

func Sum(a int, b int) (int, error) {
    c := a + b
    if c == 0 {
        return c, errors.New("Result is Zero")

    return c, nil
}

    sum, error := Sum(0, 0)
    if error != nil {
        fmt.Println("Error Msg : ", error)
    }
    fmt.Println("Sum:", sum)
}

<?php

    $b=(int)$b;
    $c=$a+$b;
    if($c==0){

    }
    return array($c,false);

$data=Sum(0,0);
$sum=$data[0];
$error=$data[1];
