ServiceProvider

Registers a configured PDO database connection.

The provider resolves the active driver from database.default or from a subclass-specific $driverName. Driver definitions can extend one or more other driver definitions through extends, allowing applications to keep shared connection options in one place and override only the values that differ per connection.

Core database logger and profiler listeners are attached to the shared events manager before the connection is returned.


Properties

driverName

Optional configured driver name forced by a specialized provider.

protected ?string $driverName

Null means the provider uses database.default. Subclasses such as the read-only and dynamic database providers set this value to select a named driver while reusing the base connection-building logic.


serviceName

Stable DI service name managed by this provider.

protected string $serviceName

This value is part of the provider contract because controllers, tasks, other injectables, and replacement providers resolve services by name. Concrete providers must set it to a non-empty value.


attachedEvents

Tracks whether database listeners were attached during this PHP process.

protected static bool $attachedEvents
  • This property is static.

Methods

register

Register the shared database service.

public register(\PhalconKit\Di\DiInterface $di): void

Supported driver options include adapter, dialectClass, connection descriptor values accepted by the selected adapter, and control keys such as extends/enable that are removed before adapter construction.

Parameters:

Parameter Type Description
$di \PhalconKit\Di\DiInterface

Throws:

When driver options are invalid, adapter or dialect classes do not exist, or the adapter does not extend Phalcon's PDO adapter base class. - ConfigurationException


Inherited methods

__construct

Stores the DI container and prepares the provider for registration.

public __construct(\PhalconKit\Di\DiInterface $di): mixed

The constructor intentionally requires PhalconKit\Di\DiInterface so providers can rely on typed service helpers during configuration and registration.

Parameters:

Parameter Type Description
$di \PhalconKit\Di\DiInterface

Throws:

When a concrete provider does not define a non-empty service name. - LogicException


getName

Returns the DI service name managed by this provider.

public getName(): string

boot

Optional post-registration hook.

public boot(): void

The base implementation is intentionally empty. Custom bootstraps or application code may call this method for provider-specific startup work after all services have been registered.


configure

Optional provider-local configuration hook.

public configure(): void

This runs during construction after DI has been stored and before register() is called. Use it to normalize provider options or prepare lightweight state; service creation belongs in register().
