Merge arrays made in a loop PHP - php

Question

I have a array that, 3 repeats from the same week, but 3 differents users that have your totals separately:
array
0 =>
array
'week' => '1'
'user' => 'Oswaldo Aranha'
'totals' => 'value'
1 =>
array
'week' => '1'
'user' => 'Protogenes'
'totals' => 'value'
2 =>
array
'week' => '1'
'user' => 'Rego Barros'
'totals' => 'value'
3 =>
array
'week' => '2'
'user' => 'Oswaldo Aranha'
'totals' => 'value'
4 =>
array
'week' => '2'
'user' => 'Protogenes'
'totals' => 'value'
5 =>
array
'week' => '2'
'user' => 'Rego Barros'
'totals' => 'value'
...
I wanna to unify the week in one array, with the 3 users and your totals. Like this:
array
0 =>
array
'week' => '1'
'Oswaldo Aranha' => 'value'
'Protogenes' => 'value'
'Rego Barros' => 'value'
1 =>
array
'week' => '2'
'Oswaldo Aranha' => 'value'
'Protogenes' => 'value'
'Rego Barros' => 'value'
2 =>
array
'week' => '3'
'Oswaldo Aranha' => 'value'
'Protogenes' => 'value'
'Rego Barros' => 'value'
...
I'm trying using array_merge(), array_combine(), array_whatever() but doesn' work. How i do that?

Answer 1

you can use array_merge();
$arr=array_merge ( $array[0],$array[1] ,$array[3]);
i hope this will help you :)

Answer 2

$array = [
[
'week' => '1',
'user' => 'Oswaldo Aranha',
'totals' => 'value'
],
[
'week' => '1',
'user' => 'Protogenes',
'totals' => 'value'
],
[
'week' => '1',
'user' => 'Rego Barros',
'totals' => 'value'
],
[
'week' => '2',
'user' => 'Oswaldo Aranha',
'totals' => 'value',
],
[
'week' => '2',
'user' => 'Protogenes',
'totals' => 'value'
]
];
function combineWeeks($array) {
$results = [];
for($i = 0;$i < count($array);$i++) {
$results[$array[$i]['week']][$array[$i]['user']] = $array[$i]['totals'];
$results[$array[$i]['week']]['week'] = $array[$i]['week'];
}
$combined = [];
foreach($results as $key => $value) {
$combined[] = $results[$key];
}
return $combined;
}
Usage:
$combinedArray = combineWeeks($array);
print_r($combinedArray);
output:
Array
(
[0] => Array
(
[Oswaldo Aranha] => value
[week] => 1
[Protogenes] => value
[Rego Barros] => value
)
[1] => Array
(
[Oswaldo Aranha] => value
[week] => 2
[Protogenes] => value
)
)

Answer 3

I think there is no php-function doing it for you. Just do it your own:
$in = $array;
$out = [];
foreach ($in as $curIn) {
if ( ! isset ($out[$curIn["week"]])) {
$out[$curIn["week"]] = [];
}
$out[$curIn["week"]][$curIn["user"]] = $curIn["totals"];
}
That's it.
