PHP Array DTO

This package allows you to generate object based on array data.

This can be useful for integrations with some APIs, for example.

Installation

composer require krzar/array-dto

Usage

Simple object

use KrZar\ArrayDto\ArrayDto;

class UserData extends ArrayDto {
    public string $name;
    public string $email;
    public int $age;
    public float $money;
    public bool $isActive = false;
    public array $roles = [];
}

To create this object from array call:

$data = [
    'name' => 'Test',
    'email' => 'test@test.com',
    'age' => 99,
    'money' => 1520.50,
    'isActive' => true,
    'roles' => ['ADMIN']
];

UserData::create($data);

If any parameter is not passed any value will be assigned, so a default value should be established for such cases.

Nested object

class CompanyData extends ArrayObject {
    public string $name;
    public string $city;
    public string $street;
}

class UserData extends ArrayObject {
    public string $name;
    public string $email;
    public int $age;
    public float $money;
    public bool $isActive = false;
    public array $roles = [];
    public CompanyData $company;
}

To create this object from array call:

$data = [
    'name' => 'Test',
    'email' => 'test@test.com',
    'age' => 99,
    'money' => 1520.50,
    'isActive' => true,
    'roles' => ['ADMIN'],
    'company' => [
        'name' => 'Test Company',
        'city' => 'Test',
        'street' => 'Test Street 1'
    ]   
];

UserData::create($data);

Nested object multidimensional

If you want to create array of objects you need to configure this with $arrayMap property.

class UserData extends ArrayObject {
    public string $name;
    public string $email;
    public int $age;
    public float $money;
    public bool $isActive = false;
    public array $roles = [];
    public CompanyData $company;
    public array $children;
    
     protected function casts(): array {
        return [
            'children' => new \KrZar\ArrayDto\Casts\MultidimensionalCast(UserData::class),
        ];
     }
}

To create this object from array call:

$data = [
    'name' => 'Test',
    'email' => 'test@test.com',
    'age' => 99,
    'money' => 1520.50,
    'isActive' => true,
    'roles' => ['ADMIN'],
    'company' => [
        'name' => 'Test Company',
        'city' => 'Test',
        'street' => 'Test Street 1'
    ],
    'children' => [
        [
            'name' => 'Test 2',
            'email' => 'test2@test.com',
            'age' => 98,
            'money' => 2400,
            'isActive' => true,
            'roles' => ['MODERATOR']
        ]       
    ]       
];

UserData::create($data);

Union types

You can use union types in objects, but with some restrictions:

• built-in types can be combined in any way
• ArrayObject type can be combined only with build-in types, not with other ArrayObject

For example:

public CompanyData|string $company;

CompanyData will be created if a company index in array is array type.

Names mapping

You can map names of parameters using $namesMap array:

class UserData extends ArrayObject {
    public string $name;
    public string $email;
    public int $age;
    public float $money;
    public bool $isActive = false;
    public array $roles = [];
    public CompanyData $company;
    public array $children;

    protected function casts(): array {
            return [
                'children' => new \KrZar\ArrayDto\Casts\MultidimensionalCast(UserData::class),
                'is_active' => new \KrZar\ArrayDto\Casts\NameCast('isActive')
            ];
         }
    }

Types mapping

Types are mapped automatically.

Custom casts

You can make any custom cast and mapping to parameter. You can also provide array of casts.

class UserData extends ArrayObject {
    public string $name;
    public string $email;
    public int $age;
    public float $money;
    public bool $isActive = false;
    public array $roles = [];
    public CompanyData $company;
    public array $children;
    public int $agePlusTen;

    protected function casts(): array {
            return [
                'children' => new \KrZar\ArrayDto\Casts\MultidimensionalCast(UserData::class),
                'is_active' => new \KrZar\ArrayDto\Casts\NameCast('isActive'),
                'agePlusTen' => new \KrZar\ArrayDto\Casts\CustomCast(
                    fn(mixed $value, array $raw) => $raw['age'] + 10
                ),
            ];
         }
    }
