How to build custom array in multi level foreach? - php

Question

Here is the raw data
Array
(
[name] => me
[tickets] => Array
(
[1] => Array
(
[equipment] => Array
(
[1] => Array
(
[name] => DVR
[received] => 10
)
[2] => Array
(
[name] => DCT
[received] => 3
)
)
)
[2] => Array
(
[equipment] => Array
(
[1] => Array
(
[name] => DVR
[received] => 4
)
[2] => Array
(
[name] => DCT
[received] => 6
)
)
)
)
)
Users have multiple tickets, but each ticket has the same item with different 'received' amounts. I would like to sum the received amount into one variable/array.
Here is a demo of how I would like to get it to work like
Array
(
[name] => me
[equipment] => Array
(
[DVR] => 14
[DCT] => 9
)
)
Here is my most recent failed attempt at building my own array from a multidimensional array.
foreach($data as $user){
$sum = [];
$sum['name'] = $user->name;
$sum['equipment'] = [];
foreach($user->tickets as $ticket){
foreach($ticket->equipments as $eqpt){
$sum['equipment'][$eqpt['name']] += $eqpt['pivot']['received'];
}
}
print_r($sum);
}

Answer 1

Please try the following code. There's only a single user in your $data, though, so you need to do $data = [$data]; first.
foreach ($data as $user) {
$sum = [];
$sum['name'] = $user['name'];
$sum['equipment'] = [];
foreach($user['tickets'] as $ticket){
foreach($ticket['equipment'] as $eqpt){
$sum['equipment'][$eqpt['name']] += $eqpt['received'];
}
}
print_r($sum);
}
PHP arrays are accessed with square bracket syntax
There's probably a typo in $ticket->equipments.

Answer 2

Try with this:
$array = $data; //$data is your array
$sum = array('name' => $array['name'], 'equipment' => array());
foreach($array['tickets'] as $row) {
for($i = 0; $i < count($row); $i++) {
foreach($row['equipment'] as $infos) {
$sum['equipment'][$infos['name']] += $infos['received'];
//print_r($infos);
}
}
}
print_r($sum);

Answer 3

well, after much googling and trial and error this appears to work
$sum = [];
// $data is a collection returned by Laravel
// I am converting it to an array
foreach($data->toArray() as $user){
$items = [];
foreach($user['tickets'] as $ticket){
foreach($ticket['equipments'] as $eqpt){
$name = $eqpt['name'];
if (! isset($items[$name]))
{
$items[$name] = $eqpt['received'];
} else {
$items[$name] += $eqpt['received'];
}
}
}
$sum[] = [
'name' => $user['name'],
'equipment' => $items
];
}
