PHP에서 효율적으로 배열을 뒤집는 최고의 전략

<?php
$array = [1, 2, 3, 4, 5];
$reversedArray = array_reverse($array);
print_r($reversedArray); // 输出： [5, 4, 3, 2, 1]
?>

<?php
$array = [1, 2, 3, 4, 5];
$reversedArray = [];
for ($i = count($array) - 1; $i >= 0; $i--) {
    $reversedArray[] = $array[$i];
}
print_r($reversedArray); // 输出： [5, 4, 3, 2, 1]
?>

<?php
$array = ['name' => 'John', 'age' => 30];
$reversedArray = array_flip($array);
print_r($reversedArray); // 输出： ['John' => 'name', 30 => 'age']
?>

$orderItems = [
    ['name' => 'Product A', 'quantity' => 2],
    ['name' => 'Product B', 'quantity' => 1],
    ['name' => 'Product C', 'quantity' => 3],
];

<?php
$reversedOrderItems = array_reverse($orderItems);
foreach ($reversedOrderItems as $item) {
    echo $item['name'] . ' (' . $item['quantity'] . ')<br>';
}

Product C (3)
Product B (1)
Product A (2)
