PHP 数组逻辑重构

PHP 数组逻辑重构

我正在尝试重构我的代码...这是 PHP ...

我有以下内容:

$totals[] = "Total";
$totals[] = $counts['hole'][1] + $counts['warn'][1] + $counts['info'][1] + $counts['crit'][1];
$totals[] = $counts['hole'][2] + $counts['warn'][2] + $counts['info'][2] + $counts['crit'][2];
$totals[] = $counts['hole'][3] + $counts['warn'][3] + $counts['info'][3] + $counts['crit'][3];
$totals[] = $counts['hole'][4] + $counts['warn'][4] + $counts['info'][4] + $counts['crit'][4];
$totals[] = $counts['hole'][5] + $counts['warn'][5] + $counts['info'][5] + $counts['crit'][5];
$totals[] = $counts['hole'][6] + $counts['warn'][6] + $counts['info'][6] + $counts['crit'][6];

为什么这行不通？

for($i; $i < 6; $i++ ){
    foreach( $severity as $sev ){
        $totals[$i] = $totals[$i] + $counts[$sev][$i];
    }
}

你在 for 循环中有一个错误:

for ($i = 1; $i <= 6; $i++) {
    foreach ($severity as $sev) {
        $totals[$i] += $counts[$sev][$i];
    }
}

您忘记初始化 $i 变量。
