So i have this array that i get from query. The array look like this when i print_r
Array

[0] => Array
(
[Name] => NAME 1
[Last] => LastValue1
[Bid] =>
[Ask] =>
)
[1] => Array
(
[Name] => NAME 1
[Last] =>
[Bid] => BidValue1
[Ask] =>
)
[2] => Array
(
[Name] => Name 2
[Last] => LastValue2
[Bid] => BidValue2
[Ask] =>
)
[3] => Array
(
[Name] => NAME 1
[Last] =>
[Bid] =>
[Ask] => AskValue1
)
[4] => Array
(
[Name] =>Name 2
[Last] =>
[Bid] =>
[Ask] => AskValue2
)
)
and i want to achieve array looks like this
Array
(
[0] => Array
(
[Name] => NAME 1
[Last] => LastValue1
[Bid] => BidValue1
[Ask] => AskValue1
)
[2] => Array

I try this way (get it from google)
$result = array();
foreach ($newArray as $element) {
$result[$element['Name']][] = $element;
}
echo "<pre>";print_r($result);
But it is not showing the result that i want. How can i achieve it ?
thanks in advance and sorry for my english

Answer 1

You can use below snippet for the same,
$result = [];
foreach ($newArray as $element) {
foreach ($element as $key => $value) {
// checking if value for key is already added to result array
if ((!empty($result[$element['Name']]) && !array_key_exists($key, $result[$element['Name']])) || empty($result[$element['Name']])) {
if (!empty($value)) { // checking if value not empty
$result[$element['Name']] = ($result[$element['Name']] ?? []);
// merge it to group wise name result array
$result[$element['Name']] = array_merge($result[$element['Name']], [$key => $value]);
}
}
}
}
array_merge — Merge one or more arrays
array_key_exists — Checks if the given key or index exists in the array
Demo
Output:-
Array
(
[0] => Array
(
[Name] => NAME1
[Last] => LastValue1
[Bid] => BidValue1
[Ask] => AskValue1
)
[1] => Array
(
[Name] => Name2
[Last] => LastValue2
[Bid] => BidValue2
[Ask] => AskValue2
)
)

Answer 2

Here is the shortest and simple solution by using foreach with array_filter
foreach($a as &$v){
$v = array_filter($v);
isset($r[$v['Name']]) ? ($r[$v['Name']] += $v) : ($r[$v['Name']] = $v);
}
You can use array_values to re arrange the order of array.
