How to access the changing key in an associative multidimensional array - php

Question

I have this array:
array: [
0 => array: [
"key 1" => "user 1",
"count" => "14"
],
1 => array: [
"key 2" => "user 2",
"count" => "7"
],
2 => array: [
"key 2" => "user 1",
"count" => "1"
]
]
I have to count the count values ​​for each key. But the names of keys have different names. And I do not know how to get access to them.
I want to get such result:
array: [
0 => array: [
"user" => "user 1",
"key 1" => "14",
"key 2" => "1",
],
1 => array: [
"user" => "user 2",
"key 2" => "7"
]
I tried to use two foreach loops
foreach ($result as $k=>$v)
{
foreach ($v as $k2=>$v2) {
$final[]["user"] = $result[$k][$k2];
}
}
But the result is incorrect

Answer 1

You could try something like this :
$result = [
["key 1" => "user 1", "count" => "14"],
["key 2" => "user 2", "count" => "7"],
["key 2" => "user 1", "count" => "1"]
];
$out = [] ; // output array
foreach ($result as $val) {
$keys = array_keys($val); // get the keys "key 1", "count" as array
$uid = reset($val); // get the first value "user 1"
$out[$uid]['user'] = reset($val); // store the user name
$out[$uid][reset($keys)] = $val['count']; // store the count into "key N" key.
}
$out = array_values($out); // reindex keys
print_r($out); // output data (optional)
Outputs :
Array
(
[0] => Array
(
[user] => user 1
[key 1] => 14
[key 2] => 1
)
[1] => Array
(
[user] => user 2
[key 2] => 7
)
)

Answer 2

I assumed user x and key x were just placeholders for any values.
$b = array();
foreach ($a as $row)
{
$values = array_values($row);
$keys = array_keys($row);
//Extract data from keys / values
$user = $values[0];
$key = $keys[0];
$count = $values[1];
//Create element in output array and insert user info
if ( ! isset($b[$user]))
{
$b[$user] = array('user' => $user);
}
//Add key info
$b[$user][$key] = $count;
}
//Rewrite array keys to 0, 1, 2, ...
$b = array_values($b);
