将三个扁平的、索引的数组合并成一个扁平的、索引的数组。

Question

我想要像这样合并三个数组：

$a = array(1,2,3,4);
$b = array(5,6,7,8);
$c = array(1,2,3,4);

将它们合并成一个大数组，这样输出结果将是：

$result = array(1,2,3,4,5,6,7,8,1,2,3,4);

$a = array(1,2,3,4);
$b = array(5,6,7,8);
$c = array(1,2,3,4);

$out = array_merge($a, $b, $c);

结果：

Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
    [4] => 5
    [5] => 6
    [6] => 7
    [7] => 8
    [8] => 1
    [9] => 2
    [10] => 3
    [11] => 4
)
