如何用函数替换这些简单的if else PHP语句？

function checkCondition($condition) {
    if ($condition == 'A') {
        return 'Condition A';
    } elseif ($condition == 'B') {
        return 'Condition B';
    } elseif ($condition == 'C') {
        return 'Condition C';
    } else {
        return 'Default Condition';
    }
}

$result = checkCondition('A');
echo $result; // 输出：Condition A
