Container
in package
implements
ContainerInterface, ResetInterface
Container is a dependency injection container.
It gives access to object instances (services). Services and parameters are simple key/pair stores. The container can have four possible behaviors when a service does not exist (or is not initialized for the last case):
- EXCEPTION_ON_INVALID_REFERENCE: Throws an exception (the default)
- NULL_ON_INVALID_REFERENCE: Returns null
- IGNORE_ON_INVALID_REFERENCE: Ignores the wrapping command asking for the reference (for instance, ignore a setter if the service does not exist)
- IGNORE_ON_UNINITIALIZED_REFERENCE: Ignores/returns null for uninitialized services or invalid references

Methods
__construct()
public
__construct([ParameterBagInterface $parameterBag = null ]) : mixed
Parameters
- $parameterBag : ParameterBagInterface = null
camelize()
Camelizes a string.
public
static camelize(string $id) : string
Parameters
- $id : string
Return values
stringcompile()
Compiles the container.
public
compile() : mixed
This method does two things:
- Parameter values are resolved;
- The parameter bag is frozen.
get()
Gets a service.
public
get(string $id[, int $invalidBehavior = self::EXCEPTION_ON_INVALID_REFERENCE ]) : mixed
Parameters
- $id : string
-
Identifier of the entry to look for.
- $invalidBehavior : int = self::EXCEPTION_ON_INVALID_REFERENCE
Tags
Return values
mixed —Entry.
getParameter()
Gets a parameter.
public
getParameter(string $name) : array<string|int, mixed>|bool|string|int|float|UnitEnum|null
Parameters
- $name : string
Tags
Return values
array<string|int, mixed>|bool|string|int|float|UnitEnum|nullgetParameterBag()
Gets the service container parameter bag.
public
getParameterBag() : ParameterBagInterface
Return values
ParameterBagInterfacegetRemovedIds()
Gets service ids that existed at compile time.
public
getRemovedIds() : array<string|int, mixed>
Return values
array<string|int, mixed>getServiceIds()
Gets all service ids.
public
getServiceIds() : array<string|int, string>
Return values
array<string|int, string>has()
Returns true if the container can return an entry for the given identifier.
public
has(string $id) : bool
Returns false otherwise.
has($id) returning true does not mean that get($id) will not throw an exception.
It does however mean that get($id) will not throw a NotFoundExceptionInterface.
Parameters
- $id : string
-
Identifier of the entry to look for.
Return values
boolhasParameter()
public
hasParameter(string $name) : bool
Parameters
- $name : string
Return values
boolinitialized()
Returns true if the given service has actually been initialized.
public
initialized(string $id) : bool
Parameters
- $id : string
Return values
boolisCompiled()
Returns true if the container is compiled.
public
isCompiled() : bool
Return values
boolreset()
public
reset() : mixed
set()
Sets a service.
public
set(string $id, object|null $service) : mixed
Setting a synthetic service to null resets it: has() returns false and get() behaves in the same way as if the service was never created.
Parameters
- $id : string
- $service : object|null
setParameter()
public
setParameter(string $name, array<string|int, mixed>|bool|string|int|float|UnitEnum|null $value) : mixed
Parameters
- $name : string
- $value : array<string|int, mixed>|bool|string|int|float|UnitEnum|null
underscore()
A string to underscore.
public
static underscore(string $id) : string
Parameters
- $id : string
Return values
stringgetEnv()
Fetches a variable from the environment.
protected
getEnv(string $name) : mixed
Parameters
- $name : string
Tags
load()
Creates a service by requiring its factory file.
protected
load(string $file) : mixed
Parameters
- $file : string
__clone()
private
__clone() : mixed
make()
Creates a service.
private
make(string $id, int $invalidBehavior) : mixed
As a separate method to allow "get()" to use the really fast ?? operator.
Parameters
- $id : string
- $invalidBehavior : int
