多个多维数组按值合并

使用PHP的array_merge_recursive()函数来合并多个多维数组。

下面是一个示例代码：

$arr1 = array( "color" => array("favorite" => "red"), 5, 10 );

$arr2 = array( "color" => array("favorite" => "green", "blue"), 15 );

$arr3 = array( "color" => array("favorite" => "blue"), 20 );

$result = array_merge_recursive($arr1, $arr2, $arr3);

print_r($result);

//输出结果为： /* Array ( [color] => Array ( [favorite] => Array ( [0] => red [1] => green [2] => blue )

    )

[0] => 5
[1] => 10
[2] => 15
[3] => 20

) */
