使用布尔值(PHP)评估数组的最短方法？

<?php
// 定义数组
$arr = [
    "apple" => 1,
    "banana" => 2,
    "cherry" => 3,
    "date" => 4,
    "elderberry" => 5,
    "fig" => 6,
    "grape" => 7,
    "honeydew" => 8,
    "ice cream" => 9,
    "jackfruit" => 10,
    "kiwi" => 11,
    "lemon" => 12,
    "mango" => 13,
    "nectarine" => 14,
    "orange" => 15,
    "papaya" => 16,
    "pineapple" => 17,
    "raspberry" => 18,
    "strawberry" => 19,
    "tangerine" => 20,
    "watermelon" => 21,
    "xigua" => 22,
    "yellow passionfruit" => 23,
    "zucchini" => 24,
];

// 定义哈希表
$map = [
    1 => "apple",
    2 => "banana",
    3 => "cherry",
    4 => "date",
    5 => "elderberry",
    6 => "fig",
    7 => "grape",
    8 => "honeydew",
    9 => "ice cream",
    10 => "jackfruit",
    11 => "kiwi",
    12 => "lemon",
    13 => "mango",
    14 => "nectarine",
    15 => "orange",
    16 => "papaya",
    17 => "pineapple",
    18 => "raspberry",
    19 => "strawberry",
    20 => "tangerine",
    21 => "watermelon",
    22 => "xigua",
    23 => "yellow passionfruit",
    24 => "zucchini",
];

// 遍历数组，使用哈希表查找键
foreach ($arr as $key => $value) {
    if (array_key_exists($key, $map)) {
        $arr[$key] = $map[$key];
    }
}

// 输出结果
print_r($arr);
