Summary, reorganizing and "flatten" the entire multi-dimensional array - php

Question

Currently I have an array like :
Array(
[0] => Array([range]=>1-10 [count]=>3 [type]=>A)
[1] => Array([range]=>11-20 [count]=>6 [type]=>A)
[2] => Array([range]=>21-30 [count]=>5 [type]=>A)
[3] => Array([range]=>1-10 [count]=>5 [type]=>B)
[4] => Array([range]=>11-20 [count]=>3 [type]=>B)
[5] => Array([range]=>21-30 [count]=>8 [type]=>B)
[6] => Array([range]=>1-10 [count]=>4 [type]=>C)
[7] => Array([range]=>11-20 [count]=>3 [type]=>C)
[8] => Array([range]=>21-30 [count]=>6 [type]=>C)
[9] => Array([range]=>1-10 [count]=>3 [type]=>D)
[10] => Array([range]=>11-20 [count]=>7 [type]=>D)
And then I am trying to regroup/remake the array depends on their type and the expected output would be like :
Array(
[0] => Array([type]=>A [1-10]=>3 [11-20]=>6 [21-30]=>5)
[1] => Array([type]=>B [1-10]=>5 [11-20]=>3 [21-30]=>8)
[2] => Array([type]=>C [1-10]=>4 [11-20]=>3 [21-30]=>6)
[3] => Array([type]=>D [1-10]=>3 [11-20]=>7)
)
I have tried array_column but isn't what exactly I want...
Example Here.
Thanks in advance.

This should work for you:
Here I simply loop through the entire array and then check with isset() if the result array already has an innerArray with the same type (e.g $result["A"]), if not I add the type as value to the inner array (.e.g. $result["A"]["type"] = "A";).
After this check I simply add the range and count to each type (e.g. $result["A"]["1-10"] = 3;)
At the end I simply reindex the entire $result array with array_values().
<?php
foreach($arr as $k => $v) {
if(!isset($result[$v["type"]]))
$result[$v["type"]]["type"] = $v["type"];
$result[$v["type"]][$v["range"]] = $v["count"];
}
$result = array_values($result);
print_r($result);
?>
output:
Array
(
[0] => Array
(
[type] => A
[1-10] => 3
[11-20] => 6
[21-30] => 5
)
//...
)
