Merge two multidimensional arrays and reindex all subarrays

FIXED (again)

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.

EDIT 03/2014: Improved readability and efficiency

Try array_merge:

$result = array_merge($array1, $array2);

more simple and modern way is:

$merged = $array1 + ['apple' => 10, 'orange' => 20] + ['cherry' => 12, 'grape' => 32];
