Map array values to collection of items - laravel

Question

How would one do the following elegantly with laravel collections ?
Map the values of the $baseMap as keys to the collection.
The baseMap :
$baseMap = [
'name' => 'new_name',
'year' => 'new_year',
];
The collection :
$items = collect([
[
'name' => 'name1',
'year' => '1000',
'not_in_basemap' => 'foo'
],
[
'name' => 'name2',
'year' => '2000',
'not_in_basemap' => 'foo'
],
//...
]);
The end result :
$result =[
[
'new_name' => 'name1',
'new_year' => '1000',
],
[
'new_name'=> 'name2',
'new_year' => '2000',
],
];
I know how to do it in plain php , just wondering what a nice collection version would be. Thanks!

Answer 1

I tried to find collection methods, or php functions, but without success. Some dirty code that works with different keys from both sides (items and basemap).
$result = $items->map(function($item) use ($baseMap) {
$array = [];
foreach($baseMap as $oldKey => $newKey){
if(isset($item[$oldKey])){
$array[$newKey] = $item[$oldKey];
}
}
return $array;
});
$result = $result->toArray();

Thanks to #vivek_23 and #IndianCoding for giving me idea's I ended up with the following :
I made a small edit to make sure the mapping and the items keys lined up.
so you don't have to worry of misalignment and all in laravel collection !
$baseMap = collect($baseMap)->sortKeys();
$result = $items->map(function ($item) use ($baseMap) {
return $baseMap->values()
->combine(
collect($item)->sortKeys()->intersectByKeys($baseMap)
)
->all();
});

Answer 3

Use intersectByKeys to filter your baseMap keys with $items values.
$result = $items->map(function($item,$key) use ($baseMap){
return array_combine(array_values($baseMap),collect($item)->intersectByKeys($baseMap)->all());
});
dd($result);
Update:
In a pure collection way,
$baseMapCollect = collect($baseMap);
$result = $items->map(function($item,$key) use ($baseMapCollect){
return $baseMapCollect->values()->combine(collect($item)->intersectByKeys($baseMapCollect->all())->values())->all();
});
dd($result);

Here are my two cents, using map. Don't know how dynamic your collection should be, but knowing the keys I would do the following:
$baseMap = [
'name' => 'new_name',
'year' => 'new_year',
];
$items = collect([
[
'name' => 'name1',
'year' => '1000',
'not_in_basemap' => 'foo'
],
[
'name' => 'name2',
'year' => '2000',
'not_in_basemap' => 'foo'
],
])->map(function($item, $key) use ($baseMap) {
return [
$baseMap['name'] => $item['name'],
$baseMap['year'] => $item['year']
];
});
