Php 计算数组中连续值的数量

我已经测试了您共享的两个数组，即

$status[0]['status'] = "Green";
$status[1]['status'] = "Red";
$status[2]['status'] = "Red";
$status[3]['status'] = "Green";
$status[4]['status'] = "Green";
$status[5]['status'] = "Green";
$status[6]['status'] = "Green";
$status[7]['status'] = "Grey";

和

$status[0]['status'] = "Green";
$status[1]['status'] = "Green";
$status[2]['status'] = "Green";
$status[3]['status'] = "Green";
$status[4]['status'] = "Red";
$status[5]['status'] = "Red";
$status[6]['status'] = "Grey";
$status[7]['status'] = "Red";
$status[8]['status'] = "Grey";
$status[9]['status'] = "Green";

并且我的代码可以按预期运行.

以下是我的代码:

$status = array();
$status[0]['status'] = "Green";
$status[1]['status'] = "Green";
$status[2]['status'] = "Green";
$status[3]['status'] = "Green";
$status[4]['status'] = "Red";
$status[5]['status'] = "Red";
$status[6]['status'] = "Grey";
$status[7]['status'] = "Red";
$status[8]['status'] = "Grey";
$status[9]['status'] = "Green";

$highestCounts = array(
    'Green' => 0,
    'Red' => 0,
    'Grey' => 0
);

$currentCounts = array(
    'Green' => 0,
    'Red' => 0,
    'Grey' => 0
);

$previousStatus = '';

foreach ($status as $item) {
    $currentStatus = $item['status'];

    if ($currentStatus === $previousStatus) {
        $currentCounts[$currentStatus]++;
    } else {
        $currentCounts[$currentStatus] = 1;
    }

    $previousStatus = $currentStatus;

    // Update the highest count if necessary
    if ($currentCounts[$currentStatus] > $highestCounts[$currentStatus]) {
        $highestCounts[$currentStatus] = $currentCounts[$currentStatus];
    }
}

// Print the results
foreach ($highestCounts as $status => $count) {
    echo $status . ': ' . $count . "\n";
}
