javascript - Display data in array descending order

Solution:

you can simply sort your parent array and then take your data from that array. lets say you have an array like

$data = array(
    array(
        "name"=>"Urus", 
        "total"=>60
    ),
    array(
        "name"=>"Cayenne", 
        "total"=>85
    ),
    array(
        "name"=>"Bentayga", 
        "total"=>55
    ),
    array(
        "name"=>"Lamborghini", 
        "total"=>85
    ),
    array(
        "name"=>"Porsche", 
        "total"=>90
    ),
    array(
        "name"=>"Bentley", 
        "total"=>55
    ),
    array(
        "name"=>"Nissan", 
        "total"=>70
    ),
);
Copy code

now you want to sort that array using the total of the inner array. use array_multisort and array_column to do that.

array_multisort( array_column($data, "total"), SORT_DESC, $data );
Copy code

this will generate an sorted array like

array:7 [▼
  0 => array:2 [▼
    "name" => "Porsche"
    "total" => 90
  ]
  1 => array:2 [▼
    "name" => "Cayenne"
    "total" => 85
  ]
  2 => array:2 [▼
    "name" => "Lamborghini"
    "total" => 85
  ]
  3 => array:2 [▼
    "name" => "Nissan"
    "total" => 70
  ]
  4 => array:2 [▼
    "name" => "Urus"
    "total" => 60
  ]
  5 => array:2 [▼
    "name" => "Bentayga"
    "total" => 55
  ]
  6 => array:2 [▼
    "name" => "Bentley"
    "total" => 55
  ]
]
Copy code

and now you have nothing more to do. just loop over the array and take values.

$labels = $graph_data = [];   
foreach ($data as $key => $student) {
    if ($key < 5) {
        $labels[] = $student['name'];
        $graph_data[] = $student['total'];
    } else {
        break;
    }  
}

$array = [
    [
        'label' => 'Total Sales',
        'color' => '#fec12c',
        'data' => $graph_data
    ]
];

$graph_data = [];

return [
    'labels' => $labels,
    'datasets' => $array
];
