sorting array of array in laravel - php

Question

I have an array of array, I would like to sort it base on the number in each array
[
["Plastic and cosmetic surgery",90],
["Dermatology surgery",121],
["Infertility",134],
["Gynecology surgery",191],
["Hair transplant",92],
["Bariatrics and weight loss surgery",117],
["Dentistry",88]
]

Answer 1

There is an amazing and simple default laravel solution for this.
$collection = collect([
["Plastic and cosmetic surgery",90],
["Dermatology surgery",121],
["Infertility",134],
["Gynecology surgery",191],
["Hair transplant",92],
["Bariatrics and weight loss surgery",117],
["Dentistry",88]
]);
$sorted = $collection->sortBy(1);
$data = $sorted->values()->all();
dd($data);
Output
array:7 [▼
0 => array:2 [▼
0 => "Dentistry"
1 => 88
]
1 => array:2 [▼
0 => "Plastic and cosmetic surgery"
1 => 90
]
2 => array:2 [▼
0 => "Hair transplant"
1 => 92
]
3 => array:2 [▼
0 => "Bariatrics and weight loss surgery"
1 => 117
]
4 => array:2 [▼
0 => "Dermatology surgery"
1 => 121
]
5 => array:2 [▼
0 => "Infertility"
1 => 134
]
6 => array:2 [▼
0 => "Gynecology surgery"
1 => 191
]
]
You can check more functions like this in the documentation. I hope you will enjoy this solution.

Answer 2

Try this to sorting value by number.
Input
$array = [
["Plastic and cosmetic surgery",90],
["Dermatology surgery",121],
["Infertility",134],
["Gynecology surgery",191],
["Hair transplant",92],
["Bariatrics and weight loss surgery",117],
["Dentistry",88]
];
usort($array, 'sortByNumber');
function sortByNumber($a, $b)
{
$a = $a[1];
$b = $b[1];
if ($a == $b) return 0;
return ($a < $b) ? -1 : 1;
}
echo "<pre>";
print_r($array);
die;
Output
Array
(
[0] => Array
(
[0] => Dentistry
[1] => 88
)
[1] => Array
(
[0] => Plastic and cosmetic surgery
[1] => 90
)
[2] => Array
(
[0] => Hair transplant
[1] => 92
)
[3] => Array
(
[0] => Bariatrics and weight loss surgery
[1] => 117
)
[4] => Array
(
[0] => Dermatology surgery
[1] => 121
)
[5] => Array
(
[0] => Infertility
[1] => 134
)
[6] => Array
(
[0] => Gynecology surgery
[1] => 191
)
)
