Illuminate\Database\Eloquent\Collection {#1550 ▼
#items: array:2 [▼
0 => Modules\Ticket\Entities\Ticket {#1548 ▼
#guarded: array:1 [▶]
#connection: "mysql"
#table: "tickets"
...
#relations: array:3 [▼
"user" => App\User {#1575 ▶}
"replies" => Illuminate\Database\Eloquent\Collection {#1565 ▶}
"supporters" => Illuminate\Database\Eloquent\Collection {#1572 ▼
#items: array:1 [▼
0 => App\User {#1585 ▼
...
#attributes: array:19 [▼
"id" => 1
"user_id" => null
...
"api_token" => "a"
"remember_token" => null
"deleted_at" => null
"created_at" => "2020-06-14 13:56:45"
"updated_at" => "2020-06-14 13:56:45"
]
...
}
]
}
]
...
}
1 => Modules\Ticket\Entities\Ticket {#1567 ▼
#guarded: array:1 [▶]
#connection: "mysql"
#table: "tickets"
...
#relations: array:3 [▼
"user" => App\User {#1575 ▶}
"replies" => Illuminate\Database\Eloquent\Collection {#1551 ▶}
"supporters" => Illuminate\Database\Eloquent\Collection {#1559 ▼
#items: array:1 [▼
0 => App\User {#1585 ▼
...
#attributes: array:19 [▼
"id" => 1
"user_id" => null
...
"api_token" => "a"
"remember_token" => null
"deleted_at" => null
"created_at" => "2020-06-14 13:56:45"
"updated_at" => "2020-06-14 13:56:45"
]
...
}
]
}
]
...
}
]
}
my tested code:
#foreach($allTickets as $supporter)
#php
$unique = $supporter->supporters->unique();
#endphp
#foreach($unique->values()->all() as $user)
...
...
...
#endforeach
#endforeach

Answer 1

Do not try to do unique on the collection, try to get your data already filtered from your database. You could group by any of your relationships attributes, just pass in a closure to handle the query for the eager-loaded content, something like:
$allTickets = Ticket::with(['user','replies'])->with([
'supporters' => function($query) {
$query->groupBy('id');
}
])->whereUserId(auth()->user()->id)->get();

Answer 2

Or you can query like this:
$allTickets = collect(Ticket::with(['user','replies','supporters'])->whereUserId(auth()->user()->id)->get());
$allUniqueTickets = $allTickets->unique();
$tickets = $allUniqueTickets->values()->all();
That's how you can easily get all the unique values from your controller. I hope this answers your question.
