Array

array_except_value()

Remove the given values from the array:

$array = ['foo', 'bar', 'baz'];
$array = array_except_value($array, 'baz');

// ['foo', 'bar']
$array = ['foo', 'bar', 'baz'];
$array = array_except_value($array, ['bar', 'baz']);

// ['foo']

multiarray_set()

Set a 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 few 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],
// ]

You can set required 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],
// ]
