[c] => 1
)
)
Second Array:

FIXED(again)
固定（再次）
function array_merge_to_indexed () {
$result = array();
foreach (func_get_args() as $arg) {
foreach ($arg as $innerArr) {
$result[] = array_values($innerArr);
}
}
return $result;
}
Accepts an unlimited number of input arrays, merges all sub arrays into one container as indexed arrays, and returns the result.
接受无限数量的输入数组，将所有子数组合并到一个容器中作为索引数组，并返回结果。

more simple and modern way is:
更简单和现代的方法是：
$merged = $array1 + ['apple' => 10, 'orange' => 20] + ['cherry' => 12, 'grape' => 32];

If you want to return the exact result you specify in your question then something like this will work
如果您想返回您在问题中指定的确切结果，那么这样的事情将起作用
function array_merge_no_keys() {
$result = array();
$arrays = func_get_args();
foreach( $arrays as $array ) {
if( is_array( $array ) ) {
foreach( $array as $subArray ) {
$result[] = array_values( $subArray );
}
}
}
return $result;
}

array_mergedoes the trick:
array_merge可以解决问题：
$a = array(array(1,2,3), array(3,2,1));
$b = array(array(4,5,6), array(6,5,4));
var_dump(array_merge($a, $b));
Try it: http://codepad.org/Bf5VpZOr
试试看：http: //codepad.org/Bf5VpZOr
Exactly the wanted result.
正是想要的结果。

You could also use : array_merge_recursive; for multidimensional arrays.
你也可以使用：array_merge_recursive; 对于多维数组。
<?php
$ar1 = array("color" => array("favorite" => "red"), 5);
$ar2 = array(10, "color" => array("favorite" => "green", "blue"));
$result = array_merge_recursive($ar1, $ar2);
print_r($result);
?>
Result :
结果 ：
Array(
[color] => Array
(
[favorite] => Array
(
[0] => red
[1] => green
)
[0] => blue
)
[0] => 5
[1] => 10
)
