PHP – Group output with same ID from within foreach loop - php

Question

I have a user upload a .csv file from the backend of Wordpress through a custom file upload field (Advanced custom fields). I then call this field to retrieve the data from that file to create an array of said data:
$upload_cq = get_field('report_current_quarter');
$report_cq = array();
if(($handle_cq = fopen($upload_cq, "r")) !== FALSE)
{
while(($data_cq = fgetcsv($handle_cq, 1000, ",")) !== FALSE)
{
$report_cq[] = $data_cq;
}
$results_cq = array_slice($report_cq, 3); // remove unwanted row
fclose($handle_cq);
}
Once I create the array, I then create another array with a key and associate value, and ensure that the "team_id" column is present & not empty, as so (there is a teamName function which I won't get into):
foreach($results_cq as $results)
{
$team_id = $results[6];
if(!empty($team_id))
{
$team_totals_cq[] = array(
'id' => $team_id,
'team' => teamName($team_id),
'total_volume' => $results[41],
'total_closed' => $results[24],
'listings_closed' => $results[22],
'buyers_closed' => $results[23],
'total_agc' => $results[29],
'rental_agc' => $results[30],
);
}
}
echo '<pre>'; print_r($team_totals_cq); echo '</pre>';
When printing the array, I get the following. My question now is; How do I group results with the same team "id" and add up their results (results = total_volume, total_closed, listings_closed, buyers_closed, total_agc, and rental_agc):
Array
(
...
[6] => Array
(
[id] => 0011
[team] => Williamson Team
[total_volume] => $990,000
[total_closed] => 4
[listings_closed] => $0.00
[buyers_closed] => 1
[total_agc] => $20,812.50
[rental_agc] => $23,812.50
)
...
[9] => Array
(
[id] => 0011
[team] => Williamson Team
[total_volume] => $415,000
[total_closed] => 2
[listings_closed] => $0.00
[buyers_closed] => 0
[total_agc] => $12,450.00
[rental_agc] => $12,450.00
)
...
)
I have tried everything within my abilities, and nothing has worked.

One method is to use team_id as keys in $team_totals_cq then simply add up the values as you go through the loop.
(Note: The preg_replace function strips anything that aren't numbers or .)
$team_totals_cq = [];
foreach ($results_cq as $results) {
$team_id = $results[6];
if (!empty($team_id)) {
if (!isset($team_totals_cq[$team_id])) {
$team_totals_cq[$team_id] = [
'id' => $team_id,
'team' => teamName($team_id),
'total_volume' => preg_replace("/[^0-9\.]/", '', $results[41]),
'total_closed' => $results[24],
'listings_closed' => preg_replace("/[^0-9\.]/", '', $results[22]),
'buyers_closed' => $results[23],
'total_agc' => preg_replace("/[^0-9\.]/", '', $results[29]),
'rental_agc' => preg_replace("/[^0-9\.]/", '', $results[30])
];
} else {
$team_totals_cq[$team_id]['total_volume'] += preg_replace("/[^0-9\.]/", '', $results[41]);
$team_totals_cq[$team_id]['total_closed'] += $results[24];
$team_totals_cq[$team_id]['listings_closed'] += preg_replace("/[^0-9\.]/", '', $results[22]);
$team_totals_cq[$team_id]['buyers_closed'] += $result[23];
$team_totals_cq[$team_id]['total_agc'] += preg_replace("/[^0-9\.]/", '', $results[29]);
$team_totals_cq[$team_id]['rental_agc'] += preg_replace("/[^0-9\.]/", '', $results[30]);
}
}
}
