Array

array_except_value()

Remove the given values from the array:

array_except_value(['foo', 'bar', 'baz'], 'baz');

// ["foo", "bar"]

array_except_value(['foo', 'bar', 'baz'], ['bar', 'baz']);

// ["foo"]

multiarray_set()

Set the value for each item of the multidimensional array using "dot" notation:

$array = [
    ['name' => 'Mercedes-Benz', 'details' => ['type' => 'SUV']],
    ['name' => 'BMW', 'details' => ['type' => 'SUV']],
    ['name' => 'Porsche', 'details' => ['type' => 'SUV']],
];

multiarray_set($array, 'details.country', 'Germany');

// [
//     ["name" => "Mercedes-Benz", "details" => ["type" => "SUV", "country" => "Germany"]],
//     ["name" => "BMW", "details" => ["type" => "SUV", "country" => "Germany"]],
//     ["name" => "Porsche", "details" => ["type" => "SUV", "country" => "Germany"]],
// ]

multiarray_sort_by()

Sort the multidimensional array by several fields:

$array = [
    ['name' => 'Mercedes-Benz', 'model' => 'GLS', 'price' => 120000],
    ['name' => 'Mercedes-Benz', 'model' => 'GLE Coupe', 'price' => 110000],
    ['name' => 'BMW', 'model' => 'X6', 'price' => 77000],
    ['name' => 'Porsche', 'model' => 'Cayenne', 'price' => 117000],
];

$sorted = multiarray_sort_by($array, 'name', 'model');

// [
//     ["name" => "BMW", "model" => "X6", "price" => 77000],
//     ["name" => "Mercedes-Benz", "model" => "GLE Coupe", "price" => 110000],
//     ["name" => "Mercedes-Benz", "model" => "GLS", "price" => 120000],
//     ["name" => "Porsche", "model" => "Cayenne", "price" => 117000],
// ]

Also, you can change the sort order:

$array = [
    ['name' => 'Mercedes-Benz', 'model' => 'GLS', 'price' => 120000],
    ['name' => 'Mercedes-Benz', 'model' => 'GLE Coupe', 'price' => 110000],
    ['name' => 'BMW', 'model' => 'X6', 'price' => 77000],
    ['name' => 'Porsche', 'model' => 'Cayenne', 'price' => 117000],
];

$sorted = multiarray_sort_by($array, 'name', SORT_ASC, 'model', SORT_DESC);

// [
//     ["name" => "BMW", "model" => "X6", "price" => 77000],
//     ["name" => "Mercedes-Benz", "model" => "GLS", "price" => 120000],
//     ["name" => "Mercedes-Benz", "model" => "GLE Coupe", "price" => 110000],
//     ["name" => "Porsche", "model" => "Cayenne", "price" => 117000],
// ]

Artisan

call_in_background()

Call the given artisan console command in background.

Code execution continues immediately, without waiting for results.

call_in_background('report');

// "php artisan report" would be called in background

Optional before and after sub-commands could be used:

// "sleep 0.3 && php artisan report:monthly subscriptions" would be called in background
