how to use array_map/array_walk function for multidimensional array - php

Question

I have the following multidimensional array:
array (size=2)
10 =>
array (size=7)
1 =>
array (size=4)
0 => string '10view1' (length=7)
1 => string '10ins1' (length=6)
2 => string '10edit1' (length=7)
3 => string '10del1' (length=6)
2 =>
array (size=4)
0 => string '10view2' (length=7)
1 => string '10ins2' (length=6)
2 => string '10edit2' (length=7)
3 => string '10del2' (length=6)
3 =>
array (size=4)
0 => string '10view3' (length=7)
1 => string '10ins3' (length=6)
2 => string '10edit3' (length=7)
3 => string '10del3' (length=6)
11 =>
array (size=7)
1 =>
array (size=4)
0 => string '11view1' (length=7)
1 => string '11ins1' (length=6)
2 => string '11edit1' (length=7)
3 => string '11del1' (length=6)
2 =>
array (size=4)
0 => string '11view2' (length=7)
1 => string '11ins2' (length=6)
2 => string '11edit2' (length=7)
3 => string '11del2' (length=6)
3 =>
array (size=4)
0 => string '11view3' (length=7)
1 => string '11ins3' (length=6)
2 => string '11edit3' (length=7)
3 => string '11del3' (length=6)
I want to convert it to the array like:
1 => array(10 => array(
0 => string '10view1' (length=7)
1 => string '10ins1' (length=6)
2 => string '10edit1' (length=7)
3 => string '10del1' (length=6)),
11 => array(
0 => string '11view1' (length=7)
1 => string '11ins1' (length=6)
2 => string '11edit1' (length=7)
3 => string '11del1' (length=6)
)
),
2 => array(
10 => array(
0 => string '10view2' (length=7)
1 => string '10ins2' (length=6)
2 => string '10edit2' (length=7)
3 => string '10del2' (length=6)
),
11 => array(
0 => string '11view2' (length=7)
1 => string '11ins2' (length=6)
2 => string '11edit2' (length=7)
3 => string '11del2' (length=6)
)
),
3 => array(
10 => array(
0 => string '11view3' (length=7)
1 => string '11ins3' (length=6)
2 => string '11edit3' (length=7)
3 => string '11del3' (length=6)
),
11 => array(
0 => string '11view1' (length=7)
1 => string '11ins1' (length=6)
2 => string '11edit1' (length=7)
3 => string '11del1' (length=6)
)
)
please help me i confuse to solve this problem thanks in advance.
It's quite obvious for me how to implement this using foreach loop, but I wonder if it's possible to do this with PHP array functions like array_map or array_walk. Please use PHP 5.3 for the callback function. Thank you!

Using array map you can achieve like this
<?php
function merge_array($n, $m)
{
$data = array();
$data[10] = $n;
$data[11] = $m;
return $data;
}
$c = array_map("merge_array", $array[10], $array[11]);
print_r($c);
Using for loop it is very simple you can achieve like this
$count_10 = count($array[10]);
$count_11 = count($array[11]);
$count = ($count_10>$count_11)?$count_10:$count_11;
$data = array();
for($i=0; $i<$count; $i++)
{
if(isset($array[10][$i]))
{
$data[$i][] = $array[10][$i];
}
if(isset($array[11][$i]))
{
$data[$i][] = $array[11][$i];
}
}
