Laravel 5.3 : issues in json structure after removing an item from an array [duplicate]

Question

I have an array like this

Array
(
    [0] => Array
        (
            [title] => first 
            [description] => first item
        )

    [1] => Array
        (
            [title] => second 
            [description] => second item
        )

)

And remove an item from the array using collection forget() method

$new = collect($arr);
$new->forget(0);
echo json_encode($new->all());

Here is the json output of the above

{"1":{"title":"second ","description":"second item"}}

But i am expecting a json like this

[{"title":"second ","description":"second item"}]

Also how can i re index the above array after applying forget() method??

Start Array

Array
(
    [0] => Array
        (
            [title] => first 
            [description] => first item
        )

    [1] => Array
        (
            [title] => second 
            [description] => second item
        )

)

You remove the first element of the array:

Array
(
    [1] => Array
        (
            [title] => second 
            [description] => second item
        )

)

json_encode on this array, returns this:
{"1":{"title":"second ","description":"second item"}}

So the output that you have, is correct.

You need to run json_encode on this array, for the output that you want:

Array
(
    [title] => second 
    [description] => second item
)

You can use, for example, the array_shift function for this:

$new = collect($arr);
$new->forget(0);
echo json_encode(array_shift($new->all()));

Another example is the array_values function, in case you want more than one array:

$new = collect($arr);
$new->forget(0);
echo json_encode(array_values($new->all()));
