README

A simple PHP library that facilitates autowired dependency injection by fetching class constructor dependencies from one or more PSR-11 containers.

Autowire uses the PHP reflection API to peek at constructor parameter types and injects required and optional dependencies from assigned containers.

📂 Tomrf\Autowire\Autowire::class

Minimal class that facilitates dependency injection by autowiring class constructor dependencies from one or more PSR-11 containers.

resolveDependencies()

Returns array of resolved dependencies for a class constructor.

Dependencies are resolved from one or more PSR-11 containers.

Throws AutowireException if a required dependency could not be met using available containers.

public function resolveDependencies(
    object|string $classOrObject,
    Psr\Container\ContainerInterface $containers
): array

@throws   \Tomrf\Autowire\AutowireException
@return   (null|object)[]

instantiateClass()

Return a new instance of a class after successfully resolving all required dependencies using provided containers.

Throws AutowireException if the class does not exist or if a required dependency could not be met using available containers.

public function instantiateClass(
    string $class,
    Psr\Container\ContainerInterface $containers
): object

@throws   \Tomrf\Autowire\AutowireException

listDependencies()

Returns an array of all dependencies (method parameters) and relevant attributes for a given class or object/callable.

public function listDependencies(
    object|string $classOrObject,
    string $methodName = '__construct'
): array

@throws   \Tomrf\Autowire\AutowireException
@return   array<string,bool|string>[] Array of parameters with attributes
