循环内的多维数组合并操作

Question

let's say I have two arrays like so:

$array1 = array('A' => array(
        'B' => array(
            'C' => array(
                'D' => array(
                    'data' => array(
                        0 => array(
                            'id' => 1,
                            'name' => 'name 1'),
                        1 => array(
                            'id' => 2,
                            'name' => 'name 2')))))));

$array2 = array('A' => array(
        'B' => array(
            'C' => array(
                'E' => array(
                    'data' => array(
                        0 => array(
                            'id' => 3,
                            'name' => 'name 3'),
                        1 => array(
                            'id' => 4,
                            'name' => 'name 4')))))));

As you can see, the two arrays have the same key A, B, and C but the keys are different afterwards. How do I merge these two arrays into something like this:

$final_array = array('A' => array(
                'B' => array(
                    'C' => array(
                        'D' => array(
                            'data' => array(
                                0 => array(
                                    'id' => 1,
                                    'name' => 'name 1'),
                                1 => array(
                                    'id' => 2,
                                    'name' => 'name 2'))), 
                        'E' => array(
                            'data' => array(
                                0 => array(
                                    'id' => 3,
                                    'name' => 'name 3'),
                                1 => array(
                                    'id' => 4,
                                    'name' => 'name 4')))))));

As you can see, in this case I merge the arrays together into the same array that contains different keys for both. In order words, here I'm putting the array starting from key E from the second array into the array with index C.

Any help will be appreciated, thanks

EDIT: Now, how about if my arrays ($array1, $array2, $array3, $array4, etc...) are generated inside a foreach loop, how do I merge all of those arrays together (Notice that I do not know the number of arrays beforehand)

Answer 1

http://php.net/manual/en/function.array-merge-recursive.php

print_r(array_merge_recursive($array1, $array2));

This should do the trick.

Added:

$collection=array();
foreach() {
     $collection[]=$myArray; //here you add your array to collection
} 
print_r(call_user_func_array('array_merge_recursive', $collection));
