在php中查找二维数组中缺少的值，并插入缺少的元素

<?php
// 原始的二维数组
$originalArray = [
    ["id" => 1, "name" => "John"],
    ["id" => 2, "name" => "Jane"],
    ["id" => 3, "name" => "Mike"],
    ["id" => 4, "name" => "Alice"],
];

// 期望的值的数组
$expectedValues = [
    ["id" => 1, "name" => "John"],
    ["id" => 2, "name" => "Jane"],
    ["id" => 3, "name" => "Mike"],
    ["id" => 4, "name" => "Alice"],
    ["id" => 5, "name" => "Bob"], // 假设该元素缺失
];

// 获取所有实际出现的值
$actualValues = array_column($originalArray, null, "id");

// 比较期望的值的数组和实际出现的值的数组，得到缺少的元素
$missingElements = array_diff_key($expectedValues, $actualValues);

// 将缺少的元素逐个插入原始的二维数组中
foreach ($missingElements as $missingElement) {
    $originalArray[] = $missingElement;
}

// 输出结果
print_r($originalArray);
?>
