如何从关联数组中获取值数组？

关联数组示例:

Array
(
    [0] => Array
        (
            [0] => 1
            [1] => 2
            [2] => 3
        )
    [1] => Array
        (
            [0] => 4
            [1] => 5
            [2] => 6
        )
    [2] => Array
        (
            [0] => 7
        )
)

期望的输出

Array
(1,2,3,4,5,6,7)
