Question

我的数组有问题，当数据等于数据库内的数据时，数组中的值不想添加（+1）。

有人可以帮助我，谢谢。抱歉英语/语法不好。

案例：

A B C D E // answer
0 0 0 0 0 // count
0 1 0 0 0 // user answer B
1 1 0 0 0 // user answer A
1 2 0 0 0 // user answer B again

代码：

//create an array with values 0
$tempAns = array_fill(0,5,0);

//loop for every answered
foreach ($_POST['ques'] as $key){
    //loop for every answer from DB
    foreach ($_POST['ans_item'] as $value){
        //if answered same with answer from DB (answer is stored inside DB) 
        if($key == $value)
            //values in array will +1, depends on the node 0-4
            $tempAns++;
    }
}

Answer 1

我不确定您的实施背后的逻辑是什么，但我认为以下内容可以帮助您：

$tempAns = array ( "A" => 0, "B" => 0, "C" => 0, "D" => 0, "E" => 0);

foreach(_$POST['ques'] as $key) {
   $tempAns[$key]++;
}

它假定ques包含类似的内容：

ques = {"A", "A", "B", "E", ...}

Answer 2

最后经过几次尝试，结合@Pooya回答：

$size = $_POST['tempVar'] + 1;
$tempArray = array_fill(0, $size, 0);

echo "<br />";
foreach ($_POST['ques'] as $key){
    $a=0;
    foreach ($ans_item as $value){
        if($key == $value){
            $tempArray[$a]++;
        }
        $a++;
    }
}

谢谢@Pooya！

也感谢那些低估我的帖子的人！
