I have a laravel collection which I have sorted by the property 'name'.
{
"0":{"id":2,"name":"1","days":["2017-04-06","2017-04-07"]},
"1":{"id":3,"name":"2","days":["2017-04-08","2017-04-09"]},
"2":{"id":4,"name":"3","days":["2017-04-10","2017-04-11"]},
"6":{"id":10,"name":"4","days":["2017-04-12","2017-04-13"]},
"3":{"id":5,"name":"5","days":["2017-04-14","2017-04-15"]},
"4":{"id":6,"name":"6","days":["2017-04-16","2017-04-17"]},
"5":{"id":7,"name":"7","days":["2017-04-18","2017-04-19"]}
}
However the index of this collection has not changed. The indexes are now 0,1,2,6,3,4,5. Is it possible to re-index the collection in the order of the sorted collection?
So what I would like to have is:
{
"0":{"id":2,"name":"1","days":["2017-04-06","2017-04-07"]},
"1":{"id":3,"name":"2","days":["2017-04-08","2017-04-09"]},
"2":{"id":4,"name":"3","days":["2017-04-10","2017-04-11"]},
"3":{"id":10,"name":"4","days":["2017-04-12","2017-04-13"]},
"4":{"id":5,"name":"5","days":["2017-04-14","2017-04-15"]},
"5":{"id":6,"name":"6","days":["2017-04-16","2017-04-17"]},
"6":{"id":7,"name":"7","days":["2017-04-18","2017-04-19"]}
}
I tried using $collection->values(). But then I am left with:
[
{"id":2,"name":"1","days":["2017-04-06","2017-04-07"]},
{"id":3,"name":"2","days":["2017-04-08","2017-04-09"]},
{"id":4,"name":"3","days":["2017-04-10","2017-04-11"]},
{"id":10,"name":"4","days":["2017-04-12","2017-04-13"]},
{"id":5,"name":"5","days":["2017-04-14","2017-04-15"]},
{"id":6,"name":"6","days":["2017-04-16","2017-04-17"]},
{"id":7,"name":"7","days":["2017-04-18","2017-04-19"]}
]

If you are not familiar with Laravel Collections, then check out my Laravel Collections guide. Laravel search () is a built-in collections method that is used to search the collection for a given value. If the value is present in the collection, the key of the value is returned. If the value does not match any item, false is returned.
As Laravel Collections docs says you can use values () on a collection for reseting the indexes: $resetedIndexesCollection = $yourcollection->values (); The values method returns a new collection with the keys reset to consecutive integers.
In laravel 8.x use transform , Unlike most other collection methods, transform modifies the collection itself. If you wish to create a new collection instead, use the map method.

If you want to remove some fields from your collection, use reject method. Hope it helps you. Have a great day. Show activity on this post.

In your case is not working because you don't have a collection, you have a json, at first you need to json_decode it to create an array and then collect the array, now you have a collection and you can apply the values() method for reseting the indexes, like this:
collect(json_decode('{
"0":{"id":2,"name":"1","days":["2017-04-06","2017-04-07"]},
"1":{"id":3,"name":"2","days":["2017-04-08","2017-04-09"]},
"2":{"id":4,"name":"3","days":["2017-04-10","2017-04-11"]},
"3":{"id":10,"name":"4","days":["2017-04-12","2017-04-13"]},
"4":{"id":5,"name":"5","days":["2017-04-14","2017-04-15"]},
"5":{"id":6,"name":"6","days":["2017-04-16","2017-04-17"]},
"6":{"id":7,"name":"7","days":["2017-04-18","2017-04-19"]}
}'))->values();
This is the result:
Collection {#287 ▼
#items: array:7 [▼
0 => {#288 ▼
+"id": 2
+"name": "1"
+"days": array:2 [▶]
}
1 => {#407 ▼
+"id": 3
+"name": "2"
+"days": array:2 [▶]
}
2 => {#408 ▼
+"id": 4
+"name": "3"
+"days": array:2 [▶]
}
3 => {#409 ▼
+"id": 10
+"name": "4"
+"days": array:2 [▶]
}
4 => {#410 ▼
+"id": 5
+"name": "5"
+"days": array:2 [▶]
}
5 => {#411 ▼
+"id": 6
+"name": "6"
+"days": array:2 [▶]
}
6 => {#412 ▼
+"id": 7
+"name": "7"
+"days": array:2 [▶]
}
