Asterisk notation
-----------------

[](#asterisk-notation)

```
use Setnemo\Asterisk;

$items = new Asterisk([
    'Europe' => [
        'Ukraine' => [
            'capital' => 'Kyiv',
            'currency' => 'UAH'
        ],
        'Poland' => [
            'capital' => 'Warsaw',

        ],

    ],
    'Africa' => [
        'South Africa' => [
            'capital' => 'Capetown',
            'currency' => 'ZAR'
        ],

$resultTrue = $items->has('*.*.capital', $city);
$resultFalse = $items->has('Africa.*.capital', $city);
if ($resultTrue === true && $resultFalse === false) {
    echo "Wow! It works correctly!";
}
```

Install
-------

[](#install)

Install the latest version using Composer:

```
composer require setnemo/asterisk-notation
```

Usage
-----

[](#usage)

Create a new \\Setnemo\\Asterisk object:

```
use Adbar\Dot;
use Setnemo\Asterisk;
$asterisk = new Asterisk;
$array = ['first_one' => ['second' => 'value'], 'first_two' => ['second' => 'value'],];
// With existing array
$asterisk = new Asterisk($array);
// With existing \Adbar\Dot
$dot = new Dot($array);
$asterisk = new Asterisk($dot);
// or existing Asterisk
$newAsterisk = new Asterisk($asterisk);
```

Methods
-------

[](#methods)

Asterisk has the following methods:

- [add()](#add)
- [all()](#all)
- [clear()](#clear)
- [count()](#count)
- [delete()](#delete)
- [flatten()](#flatten)
- [get()](#get)
- [has()](#has)
- [isEmpty()](#isempty)
- [merge()](#merge)
- [mergeRecursive()](#mergerecursive)
- [mergeRecursiveDistinct()](#mergerecursivedistinct)
- [pull()](#pull)
- [push()](#push)
- [replace()](#replace) // use Dot::replace(), **need write tests**, because used get(), set()
- [set()](#set)
- [setArray()](#setarray)
- [setReference()](#setreference)
- [toJson()](#tojson) // use Dot::toJson(), **need write tests**, because used get()

### add()

[](#add)

Using for adding element with asterisk in key

> Work like [Adbar\\Dot::add()](https://github.com/adbario/php-dot-notation#add)

### all()

[](#all)

> Work like [Adbar\\Dot::all()](https://github.com/adbario/php-dot-notation#all)

### clear()

[](#clear)

Deletes the contents of a given key (sets an empty array):

```
$asterisk->clear('department.*.write_rules');

// Equivalent vanilla PHP
$array['department']['project1']['write_rules'] = [];
$array['department']['project2']['write_rules'] = [];
$array['department']['projectN']['write_rules'] = [];
```

Multiple keys:

```
$asterisk->clear(['department.*.write_rules', 'department.*.read_rules']);
```

All the stored items:

```
$asterisk->clear();

// Equivalent vanilla PHP
$array = [];
```

> If key not contains \* (asterisk) - it works like [Adbar\\Dot::clear()](https://github.com/adbario/php-dot-notation#clear)

### count()

[](#count)

Returns the number of items in a given key:

```
$asterisk->count('user.siblings');
```

Items in the root of Dot object:

```
$asterisk->count();

// Or use count() function as Dot implements Countable
count($asterisk);
```

> If key not contains \* (asterisk) - it works like [Adbar\\Dot::count()](https://github.com/adbario/php-dot-notation#count)

### delete()

[](#delete)

Deletes the given key:

```
$asterisk->delete('*.name');

// ArrayAccess
unset($asterisk['user1.name']);
unset($asterisk['user2.name']);

// Equivalent vanilla PHP
unset($array['user1']['name']);
unset($array['user2']['name']);
```

Multiple keys:

```
$asterisk->delete([
    '*.name',
    '*.title'
]);
```

### flatten()

[](#flatten)

> It works like [Adbar\\Dot::flatten()](https://github.com/adbario/php-dot-notation#flatten)

### get()

[](#get)

Returns the value of a given key:

```
$result = $asterisk->get('*.name'));

// ArrayAccess
$result['user1.name'] = $asterisk['user1.name'];
$result['user2.name'] = $asterisk['user2.name'];

// Equivalent vanilla PHP
if (isset($array['user1']['name']) {
    $result['user1.name'] = $array['user1']['name'];
}
if (isset($array['user1']['name']) {
    $result['user2.name'] = $array['user2']['name'];
}
```

Returns a given default value, if the given key doesn't exist:

```
echo $asterisk->get('user.name', 'some default value');
```

> Default value not work with asterisk

### has()

[](#has)

Checks if a given key exists (returns boolean true or false):

```
$asterisk->has('user.name');

// ArrayAccess
isset($asterisk['user.name']);
```

Multiple keys:

```
$asterisk->has([
    'user.name',
    'page.title'
]);
```

With asterisk:

```
$asterisk = new \Setnemo\Asterisk(['1' => ['second' => 'value'],'2' => ['second' => 'value']]);
$asterisk->has('*.second'); // true
$asterisk = new \Setnemo\Asterisk(['1' => ['first' => ['test' => 42]],'2' => ['second' => 'value'],'3' => ['third' => ['value' => 42]]]);
$asterisk->has('*.*.value'); // true
$asterisk = new \Setnemo\Asterisk(['user1' => ['name' => 'John', 'job' => 'warrior'], 'user2' => ['name' => 'Robin', 'job' => 'archer']);
$asterisk->has('*.spouse'); // false
```

With asterisk and value:

```
$asterisk = new \Setnemo\Asterisk([]);
$asterisk->has('*', false); // false
$asterisk = new \Setnemo\Asterisk(['*' => ['second' => 'VALUE']]);
$asterisk->has('*.second', 'VALUE'); // true
$asterisk->has('*.second', 'value'); // false because lowercase
$asterisk = new \Setnemo\Asterisk(['*' => ['second' => 'value'], 0 => [0 => 0], 11 => 11]);
$asterisk->has('*.11', 11); // true
$asterisk = new \Setnemo\Asterisk(['1' => ['second' => 'value'],'2' => ['second' => '-']]);
$asterisk->has('*.second', 'value'); // false because 'second' => '-'
$asterisk = new \Setnemo\Asterisk(['1' => ['second' => 'value'],'2' => ['second' => 'value']]);
$asterisk->has('*.second', 'value'); // true
```

With asterisk and value (non-strict mode):

```
$asterisk = new \Setnemo\Asterisk([
'locations' => [
    'Europe' => [
        'Ukraine' => [
            'capital' => 'Kyiv',
            'currency' => 'UAH'
        ],
        'Poland' => [
            'capital' => 'Warsaw',
            'currency' => 'PLN'
        ],

    ],
    'Africa' => [
        'South Africa' => [
            'capital' => 'Capetown',
            'currency' => 'ZAR'
        ],
        'Nigeria' => [
            'capital' => 'Abuja',
            'currency' => 'NGN'
        ],
    ],
]]);
// third parameter is false for non-strict mode
$asterisk->has('locations.*.*.capital', 'Kyiv', false); // true
$asterisk->has('locations.*.*.currency', 'ZAR', false); // true
$asterisk->has('locations.Europe.*.currency', 'ZAR', false); // false
```

### isEmpty()

[](#isempty)

Checks if a given key is empty (returns boolean true or false):

```
$asterisk->isEmpty('user.name');

// ArrayAccess
empty($asterisk['user.name']);

// Equivalent vanilla PHP
empty($array['user']['name']);
```

Multiple keys:

```
$asterisk->isEmpty([
    'user.name',
    'page.title'
]);
```

Checks the whole Asterisk object:

```
$asterisk->isEmpty();
```

Also works with asterisk in key:

```
$asterisk = new \Setnemo\Asterisk(['user1' => ['name' => 'John'], 'user2' => ['name' => 'Robin']);
$asterisk->isEmpty('*.name'); // false
$asterisk->isEmpty('*.spouse'); // true
```

### merge()

[](#merge)

### mergeRecursiveDistinct()

[](#mergerecursivedistinct)

> It works like [Adbar\\Dot::mergeRecursiveDistinct()](https://github.com/adbario/php-dot-notation#mergeRecursiveDistinct)

### pull()

[](#pull)

Returns the value of a given key and deletes the key:

```
echo $asterisk->pull('user.name');

// Equivalent vanilla PHP < 7.0

```

> Default value not work with asterisk in query!

Returns all the stored items as an array and clears the Dot object:

```
$items = $asterisk->pull();
```

Key with asterisk:

```
$asterisk = new \Setnemo\Asterisk([['user1' => ['name' => 'John', 'job' => 'warrior'], 'user2' => ['name' => 'Robin', 'job' => 'archer'],]]);
$result = $asterisk->pull('*.name'); // ['user1.name' => 'John', 'user2.name' => 'Robin']
$all = $asterisk->all(); // ['user1' => ['job' => 'warrior'], 'user2' => ['job' => 'archer'],]

```

### push()

[](#push)

Pushes a given value to the end of the array in a given key:
