如何通过仅接管第二个数组中与第一个数组具有相同键的值来合并两个数组？

function mergeArraysByKey($array1, $array2) {
    $mergedArray = array();
    foreach ($array1 as $key => $value) {
        if (array_key_exists($key, $array2)) {
            $mergedArray[$key] = $array2[$key];
        }
    }
    return $mergedArray;
}

$array1 = array("a" => "apple", "b" => "banana", "c" => "cherry");
$array2 = array("a" => "animal", "d" => "donkey", "e" => "elephant");

$mergedArray = mergeArraysByKey($array1, $array2);
print_r($mergedArray);

Array
(
    [a] => animal
)
