Remove duplicates from multi dimentional array which include string and laravel collection

Question

This is the multidimensional array and there's two column one is string and other one is laravel collection model.

array:2 [▼
  0 => array:2 [▼
    "email" => "myfirstemail@gmail.com"
    "user" => User {#2508 ▶}
  ]
  1 => array:2 [▼
    "email" => "myfirstemail@gmail.com"
    "user" => User {#2547 ▶} //laravel collection
  ]
]

I used php multi-dimensional array remove duplicate and it won't work for this.

I wan't to remove duplicate columns by email (no need to looked at the laravel user model.) Are there any inbuilt PHP function for this ?

You can use Laravel's Collection::unique method:

$unique = collect($yourArray)->unique('email');

By passing in email into the method, you're telling Laravel to look at that specific field in your dataset, rather than the data as a whole. You can then convert it back to an array using toArray.

$unique = collect($yourArray)->unique('email')->toArray();

You can also pass a closure to the unique method to allow you to define the value that you want to compare for each object to determine uniqueness:

$unique = collect($yourArray)->unique(function ($item) {
    return $item['email'];
});
