How to get the data from a collection array in Laravel

Question

I have this Collection Array in Laravel that is from the database

 public function getdiagnosistally(){

      $jsonData = ListBuilder::all()->pluck('listdata');
        $res = $jsonData->contains('Test');
        dd($jsonData,$res);
}

I was wondering if it is possible to count the occurrences of the following data inside the collection.

I have tried using below contain method but it does not give me a true result even if there is Test inside the Collection.

 $res = $jsonData->contains('Test');

I have also tried using count method but it only gives me the total amount of the collection not the count of Test which is 2 but the result gives me 6.

 $res = $jsonData->count('Test');

The end result i was aiming is like it will be counting the occurrences of Test from the json data.

for example :-

Test = 2
Test child 1 = 4

Would you be able to advice how i can fix it?

Answer 1

Since you have a Collection, you could solve it functionally using filter and array_count_values .

1. First we decode the json to array and wrap it in a Collection.
2. Then we filter to keep only the values containing the string 'Test'
3. We use flatMap to get all these values in a single array
4. So we can finally use array_count_values to get the desired result.

code:

$testValues = $jsonData->flatMap(function($json) {
    $data = collect(json_decode($json, true)['checklist']);
    return $data->filter(function($item) {
        return str_contains($item, 'Test');
    });
});

$result = array_count_values($testValues->all());

dd($result);

Note that in this solution I assumed the first level of the json is always "checklist". If not, you have to loop over it.

Answer 2

You count the occurrences manually by iterating over collection and JSON data converted to an array.

I've just tested this and it will work for the data format you're using:

$count = 0;
$jsonData->map(function($i) use(&$count) {
    $i = json_decode($i, true);
    array_map(function($i) use(&$count) {
        if (str_contains($i, 'Test')) $count++;
    }, $i['checklist']);
});

Answer 3

For instance your database table name is "Checklist" and "test" is a column.

$count = Checklist::Select('checklist.test')->count();

You can also use where if that's the condition ->where('checklist_id', $request->id)
