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:

call_in_background('report:monthly subscriptions', 'sleep 0.3');

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

Database

db_is_sqlite()

db_is_sqlite();

// false

db_is_mysql()

Check whether the default database connection driver is mysql or not:

db_is_mysql();

// true

db_mysql_now()

Get the current MySQL datetime:

db_mysql_now();

// "2020-05-25 20:09:33"

db_mysql_variable()

Get value of the specified MySQL variable:

db_mysql_variable('hostname');

// "localhost"

Date

to_default_timezone()

Convert the given datetime to the default timezone (see app.timezone config):

to_default_timezone('2017-02-28T14:05:01Z');

// "2017-02-28 16:05:01", assuming that `app.timezone` is "Europe/Kiev"

$backtrace = backtrace_as_string();

#0  backtrace_as_string() called at [/htdocs/example/routes/web.php:15]

]);

// ["john.doe@example.com" => "John Doe", "jane.smith@example.com"]

Also, it supports simplified syntax for a single address:

to_swiftmailer_emails(['address' => 'john.doe@example.com', 'name' => 'John Doe']);

// ["john.doe@example.com" => "John Doe"]

to_symfony_emails()

$array = [
    'a simple string' => 'Hello!',
    'a float' => 1.0,
    'an integer' => 1,
    'a boolean' => true,
    'an empty array' => [],
];

$dump = get_dump($array);

// array:5 [
//     "a simple string" => "Hello!"
