如何将2个PHP数组转换为1个JSON对象数组？

<?php
// 两个PHP数组
$array1 = array("name" => "John", "age" => 30, "city" => "New York");
$array2 = array("name" => "Jane", "age" => 25, "city" => "Los Angeles");

// 合并两个数组
$mergedArray = array($array1, $array2);

// 将数组转换为JSON格式的字符串
$jsonString = json_encode($mergedArray);

// 将JSON字符串转换为JSON对象数组
$jsonArray = json_decode($jsonString);

// 打印JSON对象数组
print_r($jsonArray);
?>

Array
(
    [0] => stdClass Object
        (
            [name] => John
            [age] => 30
            [city] => New York
        )

    [1] => stdClass Object
        (
            [name] => Jane
            [age] => 25
            [city] => Los Angeles
        )
