Json Format in laravel - laravel

Question

I have this this JSON.
{
"animals": [{
"name": "Cumi-Cumi",
"data": 1000
}, {
"name": "Udang",
"data": 300
}, {
"name": "Baranang",
"data": 12000
}, {
"name": "Cumi-Cumi",
"data": 1500
}, {
"name": "Udang",
"data": 500
}, {
"name": "Baranang",
"data": 17000
}, {
"name": "Cumi-Cumi",
"data": 2500
}]
}
How can I group the data key by its name, to be like this:
{
"animals": [{
"name": "Cumi-Cumi",
"data": [
1000, 1500, 2500
]
},
{
"name": "udang",
"data": [
300, 500
]
},
{
"name": "Baranang",
"data": [
12000, 17000
]
}
]
}

It might be because I'm tired, but I can't figure out how to make this more concise...
This is a start for you anyway.
$json = '{
"animals": [{
"name": "Cumi-Cumi",
"data": 1000
}, {
"name": "Udang",
"data": 300
}, {
"name": "Baranang",
"data": 12000
}, {
"name": "Cumi-Cumi",
"data": 1500
}, {
"name": "Udang",
"data": 500
}, {
"name": "Baranang",
"data": 17000
}, {
"name": "Cumi-Cumi",
"data": 2500
}]
}';
// Start by decoding the JSON (I assume it comes as a string, if not, then ignore this).
$collection = collect(json_decode($json, true))
// Now iterate over the keys (you only have one key (animals), but I wanted to be safe).
->map(function ($item) {
// Convert the sub arrays into a Collection, then group the data against each animal name.
// Then map (iterate) over each of the animals, one at a time.
return collect($item)->groupBy('name')->map(function ($animal) {
// Reduce each animal into a single entry.
return $animal->reduce(function ($carry, $data) {
// Use the name of the animal, then push the data onto the end. Feel free to sort at this point too!
$carry['name'] = $data['name'];
$carry['data'][] = $data['data'];
return $carry;
});
// Finally, I reset the groupBy keys to ensure it matches your desired output.
})->values();
});

JustCarty's solution is probably better, but I wanted to post mine anyways.
// get json string
$json = <<<JSON
{
"animals": [{
"name": "Cumi-Cumi",
"data": 1000
}, {
"name": "Udang",
"data": 300
}, {
"name": "Baranang",
"data": 12000
}, {
"name": "Cumi-Cumi",
"data": 1500
}, {
"name": "Udang",
"data": 500
}, {
"name": "Baranang",
"data": 17000
}, {
"name": "Cumi-Cumi",
"data": 2500
}]
}
JSON;
$result = collect(json_decode($json, true)) // transform $json into a collection
->map(function ($item) { // map over it
return collect($item); // make the animals array a collection
})
->map(function ($animals) { // map over it
return $animals
->unique('name') // leave only uniquely named animals
->map(function ($item) use ($animals) { // map over them
return [
'name' => $item['name'],
'data' => $animals->where('name', $item['name'])->pluck('data')->all()
]; // replace their 'data' values by the array of 'data' from each unique animal.
});
})
->toJson(); // turn back to json string
Using PHP 7.4 shorthand closures:
$results = collect(json_decode($json, true))
->map(fn($item) => collect($item))
->map(fn($item) => $item->unique('name')->map(fn($animal) => [
'name' => $animal['name'],
'data' => $item->where('name', $animal['name'])->pluck('data')->all()
]))
->toJson();
