Question

我有一个这样的循环：

foreach ($result_new as $count){
echo "<pre>"; print_r($count);
}

这是产生的：

Array
(
[0] => Array
    (
        [0] => TomVanhecker
        [1] => PASS
        [2] => Array
            (
                [0] => Array
                    (
                    )

            )

    )

)

Array
(
[0] => Array
    (
        [0] => DonLay
        [1] => PASS
        [2] => Array
            (
                [0] => Array
                    (
                     [0] => ADDRESS CHECK FAILED
                    )

            )

    )

)

Array
(
[0] => Array
    (
        [0] => PetraBerumen
        [1] => REVIEW
        [2] => Array
            (
                [0] => Array
                    (
                        [0] => ADDRESS CHECK FAILED
                    )

            )

    )

[1] => Array
    (
        [0] => PetraBerumen
        [1] => REVIEW
        [2] => Array
            (
                [0] => Array
                    (
                        [0] => ADDRESS CHECK FAILED
                    )

            )

    )

[2] => Array
    (
        [0] => PetraBerumen
        [1] => REVIEW
        [2] => Array
            (
                [0] => Array
                    (
                        [0] => ADDRESS CHECK FAILED
                    )

            )

    )

)

我需要它来找出每次迭代中出现“ADDRESS CHECK FAILED”多少次然后进行比较。我试过这个：

foreach ($result_new as $count){
if ((in_array_r("ADDRESS CHECK FAILED", $count)) ){
$address++
}
if($address > 2){
echo "There was more than two address failures for this customer";
}

问题是$ address值随着每个循环继续递增但我只想要循环当前总数。

Answer 1

只需要在foreach循环结束时重置$ address值，这样每次它都会计算当前元素值而不是整个循环

foreach ($result_new as $count){
    if ((in_array_r("ADDRESS CHECK FAILED", $count)) ){
        $address++;
    }

    if($address > 2){
       echo "There was more than two address failures for this customer";
    }

    $address = 0;
}

如果我正确理解问题，我认为你需要做这样的事情：

function in_array_recursive_count($needle, $haystack, &$current = 0, $strict = false) {
    foreach ($haystack as $item) {
        if ($strict ? $item === $needle : $item == $needle) {
            $current++;
        }
        else if(is_array($haystack)) {
            in_array_recursive_count($needle, $haystack, $current, $strict);
        }
    }
    return $current;
}

然后，你会这样使用它：

foreach ($result_new as $count){
    $address = in_array_recursive_count("ADDRESS CHECK FAILED", $count);
    if($address > 2){
        echo "There was more than two address failures for this customer";
    }
}

PHP计算循环的每次迭代中存在多少次值
