PHP - counting in a single variable the difference in operations between two values of arrays

我的问题是，当我计算玩家的"胜利"时，它会计算前一个值和当前值中的每个胜利。

更详细，我有这个值

$a0 = 10;
$a1 = 12;
$a2 = 14;
$b0 = 20;
$b1 = 20; 
$b2 = 10;
$arr1 = array($a0, $a1, $a2);  // Martina's numbers 
$arr2 = array($b0, $b1, $b2);  // George's numbers

foreach($arr1 as $key => $val){
        if($val > $arr2[$key]){  // Martina win , +1 point  for Martina
            $martina++;
            print($martina . " ");
        }elseif($val < $arr2[$key]){   // George win , +1 point for George
            $george++;
            print($george . " "); 
        }else{  // if is Equal - no score increase 
            print("");
        } 
}

在这种情况下，乔治的得分必须是1 2，但我的代码也输出了第一次获胜的分数，以及增加的分数。

我

怎样才能让它只拖我增加的分数.. ？

希望你理解我对问题的解释，我刚开始学习这种语言。

将打印件移出foreach

$arr1 = array(10, 12, 14);  // Martina's numbers 
$arr2 = array(20, 20, 10);  // George's numbers
$alice = 0;
$bob = 0;
foreach($arr1 as $key => $val) {
    if($val > $arr2[$key]) {
        // Martina win , +1 point  for Martina
        $alice++;
    } elseif($val < $arr2[$key]) {
        // George win , +1 point for George
        $bob++;
    } 
}
print('Alice: ' . $alice . PHP_EOL);
print('Bob: ' . $bob . PHP_EOL);

终于我做到了！！

非常感谢E_p帮助解决此问题。最终和正确的代码是：

<?php
// Values of Martina's numbers
$a0 = 21;
$a1 = 2;
$a2 = 32;
//Values of George's numbers
$b0 = 22; 
$b1 = 3;  
$b2 = 13; 
//Putting the values into arrays
$arr1 = array($a0, $a1, $a2);
$arr2 = array($b0, $b1, $b2);
// Given two variables for players score
$martina = 0;
$george = 0;

foreach($arr1 as $key => $val){
            if($val > $arr2[$key]){
                $martina++;
            }elseif($val < $arr2[$key]){
                $george++;
            }
}
print($martina . " " . $george . PHP_EOL);
