PHP如何计算多维数组中的对象？

<?php
// 定义一个多维数组
$multiArray = array(
    array(
        'name' => 'John',
        'age' => 25,
        'score' => 80
    ),
    array(
        'name' => 'Jane',
        'age' => 30,
        'score' => 90
    ),
    array(
        'name' => 'Tom',
        'age' => 28,
        'score' => 85
    )
);

$totalScore = 0;
foreach ($multiArray as $item) {
    // 访问对象的属性并进行计算
    $totalScore += $item['score'];
}

echo "总分数为：" . $totalScore;
?>
