Array functions

Get an item from the array by key
ArrayType::get(['fruit' => 'apple', 'color' => 'red'], 'fruit'); // 'apple'
ArrayType::get(['fruit' => 'apple', 'color' => 'red'], 'weight'); // null
ArrayType::get(['fruit' => 'apple', 'color' => 'red'], 'weight', 15); // 15
ArrayType::get(['apple', 'red'], -1); // 'red'
Adds a value to an array with a specific key only if key not presents in an array

It's more intuitive variant to <code>$array += [$key => $value];

$array = ['fruit' => 'apple'];
ArrayType::touch($array, 'color', 'red']); // ['fruit' => 'apple', 'color' => 'red'];
ArrayType::touch($array, 'fruit', 'banana']); // ['fruit' => 'apple'];
Push element onto the end of array and returns the modified array
$a = [1,2];
ArrayType::push($a, 3); // [1,2,3]
Prepend element to the beginning of an array and returns the modified array
$a = [2,3];
ArrayType::unshift($a, 1); // [1,2,3]
Calculate the average of values in an array (array_avg)
ArrayType::average([1, 2, 3]); // 3
Check if array is associative
ArrayType::checkAssoc([1, 2, 3]); // false
ArrayType::checkAssoc(['foo' => 'bar']); // true
Check if a value exists in an array
ArrayType::contains(array $list, mixed $item);
Inserts an array after the key
ArrayType::insertAfter(['a' => 1, 'c' => 3], 'a', ['b' => 2]); // ['a' => 1, 'b' => 2, 'c' => 3]
// If the key doesn't exist
ArrayType::insertAfter(['a' => 1, 'b' => 2], 'c', ['foo' => 'bar']); // ['a' => 1, 'b' => 2, 'foo' => 'bar']
Inserts an array before the key
ArrayType::insertBefore(['a' => 1, 'c' => 3], 'c', ['b' => 2]); // ['a' => 1, 'b' => 2, 'c' => 3]
// If the key doesn't exist
ArrayType::insertBefore(['a' => 1, 'b' => 2], 'c', ['foo' => 'bar']); // ['foo' => 'bar', 'a' => 1, 'b' => 2]
Convert list of items to ranges
ArrayType::ranges([1, 3, 7, 9]); // [[1, 3], [3, 7], [7, 9]]
Unset array item by value
ArrayType::unsetValue(['a', 'b', 'c'], 'b'); // ['a', 'c']
Calculate the standard deviation of values in an array
ArrayType::deviation([1, 2, 1]); // float(0.4714045207910317)
Cast to an array

Behavior for different types:

  • array - returns as is
  • iterable - converts to a native array (iterator_to_array())
  • another - creates an array with argument ([value])
ArrayType::toArray($value);
Get the array encoded in json

If encoded value is false, true or null then returns empty array.
JSON_THROW_ON_ERROR always enabled.

ArrayType::fromJson($json): array;

Callable functions

        return 'Bar';
    }
}
enum BazUnitEnum {
    case APPLE;
} 
enum BazStringBackedEnum: string {

Get only first match of each set from regular expression matches (exclude full matches)

StringType::regexp('a1b2', '(\S)(\d)', true, false, true); // [0 => 'a', 1 => 'b']

Get only first match of the first set from regular expression matches as single scalar value

StringType::regexp('a1b2', '(\S)(\d)', true, true, true); // 'a'
Replace first string occurrence in a string

StringType::toSnakeCase('string Like this'); // 'string_like_this'
ltrim()/rtrim()/trim() replacements supports UTF-8 chars in the charlist

Use these only if you are supplying the charlist optional arg and it contains UTF-8 characters. Otherwise trim will work normally on a UTF-8 string.

trim('«foo»', '»'); // "�foo"
StringType::trim('«foo»', '»'); // "«foo"
Split text into sentences
StringType::sentences('Fry me a Beaver. Fry me a Beaver! Fry me a Beaver? Fry me Beaver no. 4?! Fry me many Beavers... End);

  [2] => 'Fry me a Beaver?',
  [3] => 'Fry me Beaver no. 4?!',
  [4] => 'Fry me many Beavers...',
  [5] => 'End'
]
Split text into words
StringType::words('Fry me many Beavers... End'); // ['Fry', 'me', 'many', 'Beavers', 'End']
Remove word from text
StringType::unword('Remove word from text', 'word'); // 'Remove from text'

Doctrine utils

DoctrineUtils activation

Manually instance a DoctrineUtils

public function __construct(private Doctrine\Persistence\ManagerRegistry $doctrine)
{
    $doctrineUtils = new Cosmologist\Gears\Doctrine\DoctrineUtils($doctrine);
}

Register DoctrineUtils as a service with Symfony DI

# config/services.yaml
services:
    _defaults:
        autowire: true

    Cosmologist\Gears\Doctrine\DoctrineUtils:
Get metadata for a persistent object or a persistent object class
$doctrineUtils->getClassMetadata(new App\Entity\User()); // object(ClassMetadata)
$doctrineUtils->getClassMetadata(App\Entity\User::class); // object(ClassMetadata)
$doctrineUtils->getClassMetadata(new App\Controller\FooController())); // null
$doctrineUtils->getClassMetadata(App\Controller\FooController::class); // null
Get real class of a persistent object (resolve a proxy class)
$doctrineUtils->getRealClass(Proxies\__CG__\App\Entity\User::class); // 'App\Entity\User'
$doctrineUtils->getRealClass(new Proxies\__CG__\App\Entity\User()); // 'App\Entity\User'
$doctrineUtils->getRealClass(App\Entity\User::class); // 'App\Entity\User'
$doctrineUtils->getRealClass(new App\Entity\User()); // 'App\Entity\User'
$doctrineUtils->getRealClass(new App\Controller\FooController()); // null
$doctrineUtils->getRealClass(App\Controller\FooController::class); // null

Symfony ExpressionLanguage utils

Create an ExpressionFunction from a callable
ExpressionFunctionUtils::fromCallable('Foo\Bar::baz'); // object(ExpressionFunction)

For example, this can be useful for injecting simple objects (like ValueObject) into a Symfony service container

class AppExtension extends Extension
{
    #[Override]
    public function load(array $configs, ContainerBuilder $container)
    {
        $container->addExpressionLanguageProvider(new class implements ExpressionFunctionProviderInterface {
            public function getFunctions(): array {
                return [ExpressionFunctionUtils::fromCallable([WalletIdentifier::class, 'create'], 'walletId')];
            }
        });

        $container
            ->getDefinition(OrderService::class)
            ->setArgument('$wallet', expr('walletId(13)'));
    }
}

Symfony Forms utils

Convert domain model constraint violation to the form constraint violation

It's maybe useful when you validate your model from form on the domain layer and want to map violations to the form.

use Cosmologist\Gears\Symfony\Form\FormUtils;
use Symfony\Component\Form\Extension\Validator\ViolationMapper\ViolationMapper;
use Symfony\Component\Validator\Exception\ValidationFailedException;

if ($form->isSubmitted()) {
     try {
         return $this->handler->create($form->getData());
     } catch (ValidationFailedException $exception) {
         $violationMapper = new ViolationMapper();
         foreach ($exception->getViolations() as $domainViolation) {
             $violationMapper->mapViolation(FormUtils::convertDomainViolationToFormViolation($domainViolation), $form);
         }
     }
}

return $form->createView();
Trait with a method implementing DataMapperInterface::mapDataToForms with default behavior

This is convenient for mapping of form data to a model via DataMapperInterface::mapFormsToData(), for example, to create a model via a constructor, in this case, the mapping of model data to a form via DataMapperInterface::mapDataToForms() will remain unchanged, and you cannot not define it, since it is required by the DataMapperInterface.

use Cosmologist\Gears\Symfony\Form\DataFormsMapperDefaultTrait;

class TransactionFormType extends AbstractType implements DataMapperInterface
{
    use DataFormsMapperDefaultTrait;

    #[Override]
    public function buildForm(FormBuilderInterface $builder, array $options): void
    {
        $builder
            ->add('name', TextType::class)
            ->setDataMapper($this);
    }

    #[Override]
    public function mapFormsToData(Traversable $forms, mixed &$viewData): void
    {
        $forms = iterator_to_array($forms);
        $viewData = new Contact($forms['name']->getData());
    }

Symfony Framework utils

Configure your Symfony application as a bundle using service container extension and configuration
namespace App;

use App\DependencyInjection\AppExtension;
use Cosmologist\Gears\Symfony\Framework\AppExtension\AppExtensionKernelInterface;
use Cosmologist\Gears\Symfony\Framework\AppExtension\RegisterAppExtensionKernelTrait;
use Override;
use Symfony\Bundle\FrameworkBundle\Kernel\MicroKernelTrait;
use Symfony\Component\DependencyInjection\Extension\ExtensionInterface;
use Symfony\Component\HttpKernel\Kernel as BaseKernel;

class Kernel extends BaseKernel implements AppExtensionKernelInterface
{
    use MicroKernelTrait;
    use RegisterAppExtensionKernelTrait;

    #[Override]
    public function getAppExtension(): ExtensionInterface
    {
        return new AppExtension();
    }
}

Symfony Messenger utils

Symfony Messenger transport to redispatch messages on kernel.terminate event

It's a convenient way to speed up your app response to clients by scheduling hard tasks after the server response, thanks to the kernel.terminate event.

Firstly, you should enable this transport:

# config/services.yaml
services:
    _defaults:
        autoconfigure: true

    Cosmologist\Gears\Symfony\Messenger\Transport\KernelTerminate\KernelTerminateTransportFactory:
# config/packages/messenger.yaml
framework:
    messenger:
        transports:
            terminate: symfony-kernel-terminate://

Then, you should define a rule to route messages to this transport:

# config/packages/messenger.yaml
framework:
    messenger:
        routing:
            App\Event\FooEvent: terminate

and

$this->messenger->dispatch(new App\Event\FooEvent('bar'));
// or
$this->messengerBus->dispatch(new App\Event\FooEvent('bar'));

Symfony PropertyAccess utils

Get the values of the property path of the object or of the array recursively
use Cosmologist\Gears\Symfony\PropertyAccessor\RecursivePropertyAccessor;

$grandfather = new Person(name: 'grandfather');
$dad = new Person(name: 'dad', parent: $grandfather);
$i = new Person(name: 'i', parent: $dad);

(new RecursivePropertyAccessor())->getValue($i, 'parent'); // [Person(dad), Person(grandfather)]

Symfony Validator utils

Simple and convenient way instance of ValidationFailedException with single ConstraintViolation
use Cosmologist\Gears\Symfony\Validator\ValidationFailedException;

ValidationFailedException::violate($foo, "Foo with invalid bar");
ValidationFailedException::violate($foo, "Foo with invalid {{ bar }}", compact('bar'));
ValidationFailedException::violate($foo, "Foo with invalid bar", propertyPath: 'bar');
