You can use Laravel Collection pluck method to only return property which you want from each array item, and after that flatten the result array with flatten

$data = [
    [
        "location_id" => 1
    ],
    [
        "location_id" => 4
    ],
    [
        "location_id" => 6
    ],
    [
        "location_id" => 7
    ],
    [
        "location_id" => 8
    ]
];

$result = collect($data)->pluck('location_id')->flatten();

Welcome to Stackoverflow.

You can use the laravel helper array flatten method: Read more about it from here: https://laravel.com/docs/9.x/helpers#method-array-flatten

// Add the helper class call in the controller header
use Illuminate\Support\Arr;

// The actual array
$array = [
    0 => [
        "location_id" => 1
    ],
    1 =>  [
        "location_id" => 4
    ],
    2 =>  [
        "location_id" => 6
    ],
    3 =>  [
        "location_id" => 7
    ],
    4 =>  [
        "location_id" => 8
    ]
];

// Flatten the array function
$result = Arr::flatten($array);

Results:

['1','4','6','7','8']

Not as clean you might want but get the job done:

$resultSet = collect($data)->map(function($item){
    return $item['location_id'];
})->toArray();

$resultString = "[";
foreach($resultSet as $item){
    $resultString .= "'{$item}'" . ",";
}
$resultString = rtrim($resultString, ","); // produces this: "['1','4','6','7','8']"

$resultString .= "]";

dd($resultString);

$data   = \Arr::pluck($array, 'location_id'); 
$result = array_map('strrev', $data);
