Merging keys in a multidimensional array - php

Question

I have this multidimensional array:
array(3) {
[0]=>
array(2) {
["casestatus"]=> string(4) "Open"
["casestatus_count"]=> int(2)
}
[1]=>
array(2) {
["casestatus"]=> string(7) "Pending"
["casestatus_count"]=> int(1)
}
[2]=>
array(2) {
["casestatus"]=> string(4) "Open"
["casestatus_count"]=> int(1)
}
}
From the array above I am able to merge based on the casestatus key as shown below:
$newArray = array();
foreach($mergedData as $data)
{
if(!isset($newArray[$data["casestatus"]]))
{
$newArray[$data["casestatus"]] = array(
"casestatus" => $data["casestatus"],
"casestatus_count" => 0
);
}
$newArray[$data["casestatus"]]["casestatus_count"] += $data["casestatus_count"];
}
var_dump($newArray);
From which I get:
array(2) {
["Open"]=>
array(2) {
["casestatus"]=> string(4) "Open"
["casestatus_count"]=> int(3)
}
["Pending"]=>
array(2) {
["casestatus"]=> string(7) "Pending"
["casestatus_count"]=> int(1)
}
}
Note how my array keys are my casestatus. So is there a way of not having this and instead have my array keys as:
array(2) {
[0]=>
array(2) {
["casestatus"]=> string(4) "Open"
["casestatus_count"]=> int(3)
}
[1]=>
array(2) {
["casestatus"]=> string(7) "Pending"
["casestatus_count"]=> int(1)
}
}

Answer 1

Just do array_values($newArray) after the process.
var_dump(array_values($newArray));
array_values()

You could create a map of status to counts, then sum them:
<?php
$tickets =
[
[
'status' => 'Open',
'count' => 2
],
[
'status' => 'Closed',
'count' => 1
],
[
'status' => 'Open',
'count' => 1
]
];
foreach($tickets as $ticket)
$status_counts[$ticket['status']][] = $ticket['count'];
foreach($status_counts as $status => $counts)
$result[] = [
'status' => $status,
'count' => array_sum($counts)
];
var_export($result);
Output:
array (
0 =>
array (
'status' => 'Open',
'count' => 3,
),
1 =>
array (
'status' => 'Closed',
'count' => 1,
),
)
However a simpler format may suffice:
$result = array_map('array_sum', $status_counts);
var_export($result);
Output:
array (
'Open' => 3,
'Closed' => 1,
)
