php monkey chooses the king

Method 1:

function monkeyKing($n,$m)
{
	$arr=range(1,$n);
	$i=0;

	while (count($arr)>1)
	{	
		for($i=1;$i<=$m-1;$i++)
		{
			
			array_push($arr, array_shift($arr));
		}

		array_shift($arr);
	}

	echo "$arr[0]";
}

monkeyKing(6,4);//5

Method 2:

function king($m ,$n)
{
//构造数组
$arr=range(1,$m);
$i = 0 ;    //设置数组指针

while(count($arr)>1)
{
   //遍历数组，判断当前猴子是否为出局序号，如果是则出局，否则放到数组最后
   if(($i+1)%$n ==0) {
    unset($arr[$i]) ;
   } else {
    array_push($arr ,$arr[$i]) ; //本轮非出局猴子放数组尾部
    unset($arr[$i]) ;   //删除
   }
   $i++ ;
}
return $arr ;
}

var_dump(king(6,4));

Method 3: //I don’t understand this method very well. I hope everyone can leave their opinions.

function yuesefu($n,$m) {  
    $r=0;  
    for($i=2; $i<=$n; $i++) {
            $r=($r+$m)%$i;  
    }
    return $r+1;  
}  
print_r(yuesefu(3,3));//2

The above introduces the PHP Monkey King, including the content. I hope it will be helpful to friends who are interested in PHP tutorials.
