是的，array_merge函數(shù)支持多維數(shù)組。當(dāng)使用array_merge函數(shù)合并多維數(shù)組時(shí)，它會(huì)將多個(gè)數(shù)組合并成一個(gè)新數(shù)組，保持原始數(shù)組的結(jié)構(gòu)。例如：

$array1 = array("a" => array("red"), "b" => array("green", "blue"));
$array2 = array("a" => array("yellow"), "b" => array("purple"));
$result = array_merge($array1, $array2);

print_r($result);

輸出結(jié)果為：

Array
(
    [a] => Array
        (
            [0] => red
            [1] => yellow
        )

    [b] => Array
        (
            [0] => green
            [1] => blue
            [2] => purple
        )
)
