Sort multidimensional arrays and objects.
This package allows you to sort multidimensional arrays and objects., (*1)
Install package via composer, (*2)
composer require sebastiansulinski/sorter
$array = [
[
'name' => 'Arthur'
],
[
'name' => 'Tom'
],
[
'name' => 'Mark'
]
];
$sorter = new Sorter($array);
// sort the array by 'name' key
$sorter->asc('name');
// two ways of printing array
echo $sorter->printR();
echo $sorter;
// get resulting, previously sorted array
$array_sorted_asc = $sorter->collection();
// reverse order and return the resulting array
$array_sorted_desc = $sorter->desc('name')->collection();
Result for the above would be, (*3)
// $array_sorted_asc
Array
(
[0] => Array
(
[name] => Arthur
)
[1] => Array
(
[name] => Mark
)
[2] => Array
(
[name] => Tom
)
)
// $array_sorted_desc
Array
(
[0] => Array
(
[name] => Tom
)
[1] => Array
(
[name] => Mark
)
[2] => Array
(
[name] => Arthur
)
)
$array = [
[
'person' => [
'name' => 'Arthur'
]
],
[
'person' => [
'name' => 'Tom'
]
],
[
'person' => [
'name' => 'Mark'
]
]
];
$sorter = new Sorter($array);
// sort ascending by child 'name' key
$array_sorted_asc = $sorter->asc(['person', 'name'])->collection();
// sort descending by child 'name' key
$array_sorted_desc = $sorter->desc(['person', 'name'])->collection();
Result, (*4)
// $array_sorted_asc
Array
(
[0] => Array
(
[person] => Array
(
[name] => Arthur
)
)
[1] => Array
(
[person] => Array
(
[name] => Mark
)
)
[2] => Array
(
[person] => Array
(
[name] => Tom
)
)
)
// $array_sorted_desc
Array
(

For the purpose of this exercise let's assume we have 3 classes with 2 properties:, (*5)
and Wallet class with one property:, (*6)
First let's try and sort the 3 instances of the objects by their name property, (*7)
$collection[] = new Tutor(['name' => 'John']);
$collection[] = new Tutor(['name' => 'Craig']);
$collection[] = new Student(['name' => 'Marcus']);
$collection[] = new Student(['name' => 'George']);
$collection[] = new Student(['name' => 'Albert']);
$collection[] = new Student(['name' => 'Tony']);
$collection[] = new Staff(['name' => 'Greg']);
$collection[] = new Staff(['name' => 'Antony']);
$sorter = new Sorter($collection);
// sort ascending by child 'name' property
$array_sorted_asc = $sorter->asc('name')->collection();
// sort descending by child 'name' property
$array_sorted_desc = $sorter->desc('name')->collection();
Result for $array_sorted_asc, (*8)
Array
(
[0] => SSD\Student Object
(
[name] => Albert
[wallet] =>
)
[1] => SSD\Staff Object
(
[name] => Antony
[wallet] =>

[2] => SSD\Tutor Object
(
[name] => Craig
[wallet] =>

[3] => SSD\Student Object
(
[name] => George
[wallet] =>

[4] => SSD\Staff Object
(

[5] => SSD\Tutor Object

[6] => SSD\Student Object
(
[name] => Marcus
[wallet] =>
)
[7] => SSD\Student Object
(
[name] => Tony
[wallet] =>
)
)
and result for $array_sorted_desc, (*9)

Sorter allows you to sort objects based on the value associated with properties of the internal / embedded objects., (*10)
Our 3 classes have a property called wallet, which is of the Wallet object type. Let's try and sort our 3 objects using the property amount of the Wallet object., (*11)
$collection[] = new Tutor([
'name' => 'John',
'wallet' => new Wallet(['amount' => 10])
]);
$collection[] = new Tutor([
'name' => 'Craig',
'wallet' => new Wallet(['amount' => 12])
]);
$collection[] = new Student([
'name' => 'Marcus',
'wallet' => new Wallet(['amount' => 13])
]);
$collection[] = new Student([
'name' => 'George',
'wallet' => new Wallet(['amount' => 21])
]);
$collection[] = new Student([
'name' => 'Albert',
'wallet' => new Wallet(['amount' => 36])
]);
$collection[] = new Student([
'name' => 'Tony',
'wallet' => new Wallet(['amount' => 50])
]);
$collection[] = new Staff([
'name' => 'Greg',
'wallet' => new Wallet(['amount' => 22])
]);
$collection[] = new Staff([
'name' => 'Antony',
'wallet' => new Wallet(['amount' => 31])
]);
$sorter = new Sorter($collection);
// sort ascending by 'amount' property of the embedded object
$array_sorted_asc = $sorter->asc(['wallet', 'amount'])->collection();
// sort descending by 'amount' property of the embedded object
$array_sorted_desc = $sorter->desc(['wallet', 'amount'])->collection();
Result for $array_sorted_asc, (*12)
