# Phalcon Support
:::info[NOTE]
All classes are prefixed with `Phalcon`
:::
## Support\AbstractLocator
Abstract
Abstract base class for service locators.
Provides a unified way to register, validate, and resolve services
from a DI container, with support for both legacy Di and new Container.
@template T of object
- **`Phalcon\Support\AbstractLocator`**
- [`Phalcon\Auth\Access\AccessLocator`](/5.23/api/phalcon_auth/#authaccessaccesslocator)
- [`Phalcon\Auth\Adapter\AdapterLocator`](/5.23/api/phalcon_auth/#authadapteradapterlocator)
- [`Phalcon\Auth\Guard\GuardLocator`](/5.23/api/phalcon_auth/#authguardguardlocator)
`Phalcon\Contracts\Container\Service\Collection` · `Phalcon\Di\DiInterface` · `Throwable`
### Method Summary
- `public __construct(mixed $container, array $services = [])`
- `public getAll(): array` — Returns the full registered service map (defaults plus any added via
- `public getClass(string $name): string` — Returns the class-string registered under the given name.
- `public has(string $name): bool` — Whether a service with the given name is registered.
- `public newInstance(string $name): object` — Retrieve a service instance from the container.
- `public register(string $name, string $definition): static` — Register a service or override an existing one.
- `protected getExceptionClass(): string` — Get the exception class to throw on errors.
- `protected getInterfaceClass(): string` — Get the interface/class that all registered services must implement.
- `protected getService(string $name): string` — Get the service class name for a given name.
- `protected getServices(): array` — Get the default services for this locator.
### Properties
- `protected Collection|DiInterface $container`
- `protected array $services = []`
### Methods
__construct()
```php
public function __construct(
mixed $container,
array $services = []
);
```
getAll()
```php
public function getAll(): array;
```
Returns the full registered service map (defaults plus any added via
register()).
getClass()
```php
public function getClass( string $name ): string;
```
Returns the class-string registered under the given name.
has()
```php
public function has( string $name ): bool;
```
Whether a service with the given name is registered.
newInstance()
```php
public function newInstance( string $name ): object;
```
Retrieve a service instance from the container.
On the `DiInterface` path this returns the container's **shared**
instance (`getShared()`) - despite the name, it is not a fresh build.
Locators whose services carry per-activation state should override this
method to resolve a fresh instance; see `Auth\Access\AccessLocator`, which uses
`ContainerResolver::resolveFresh` for exactly that reason.
register()
```php
public function register(
string $name,
string $definition
): static;
```
Register a service or override an existing one.
getExceptionClass()
```php
abstract protected function getExceptionClass(): string;
```
Get the exception class to throw on errors.
getInterfaceClass()
```php
abstract protected function getInterfaceClass(): string;
```
Get the interface/class that all registered services must implement.
This allows different locators to enforce different contracts.
getService()
```php
protected function getService( string $name ): string;
```
Get the service class name for a given name.
getServices()
```php
abstract protected function getServices(): array;
```
Get the default services for this locator.
## Support\Collection
Class
`Phalcon\Support\Collection` is a supercharged object-oriented array. It implements:
- [ArrayAccess](https://www.php.net/manual/en/class.arrayaccess.php)
- [Countable](https://www.php.net/manual/en/class.countable.php)
- [IteratorAggregate](https://www.php.net/manual/en/class.iteratoraggregate.php)
- [JsonSerializable](https://www.php.net/manual/en/class.jsonserializable.php)
It can be used in any part of the application that needs collection of data
Such implementations are for instance accessing globals `$_GET`, `$_POST`
etc.

configuration (insensitivity, strict-null, type) of the current one.
```php
protected function extractValue(
mixed $item,
string $propertyOrMethod
): mixed;
```
Extracts a single value from an item. For arrays returns the keyed
entry; for objects, prefers a callable method, then a readable
property. Returns null when nothing matches.

Checks if we need insensitive keys and if so, converts the element to
lowercase
setData()
```php
protected function setData(
string $element,
mixed $value
): void;
```
Internal method to set data
validateType()
```php
protected function validateType( mixed $value ): void;
```
Validates the value against the configured `$type` guard. When `$type`
is null this is a no-op. Scalar tokens (`int`, `string`, `bool`,
`float`, `array`, `object`) map to their `is_*` checks; anything else
is treated as a class/interface name and tested with `instanceof`.

## Support\Registry
Final
A registry is a container for storing objects and values in the application
space. By storing the value in a registry, the same object is always
available throughout your application.
```php
$registry = new \Phalcon\Registry();
// Set value
$registry->something = "something";
// or
$registry["something"] = "something";
// Get value
$value = $registry->something;
// or
$value = $registry["something"];
// Check if the key exists
$exists = isset($registry->something);
// or
$exists = isset($registry["something"]);
// Unset
unset($registry->something);
// or
unset($registry["something"]);
```
In addition to ArrayAccess, Phalcon\Registry also implements Countable
(count($registry) will return the number of elements in the registry),
Serializable and Iterator (you can iterate over the registry using a foreach
loop) interfaces. For PHP 5.4 and higher, JsonSerializable interface is
implemented.
Phalcon\Registry is very fast (it is typically faster than any userspace
implementation of the registry); however, this comes at a price:
Phalcon\Registry is a final class and cannot be inherited from.
Though Phalcon\Registry exposes methods like __get(), offsetGet(), count() etc,
it is not recommended to invoke them manually (these methods exist mainly to
match the interfaces the registry implements): $registry->__get("property")
is several times slower than $registry->property.
Internally all the magic methods (and interfaces except JsonSerializable)
are implemented using object handlers or similar techniques: this allows to
bypass relatively slow method calls.

## Support\Settings
Class
Phalcon\Support\Settings
Provides a PHP-userland layer for reading and overriding the Phalcon
extension's ini settings (orm.*, db.*, form.*).
get() checks PHP-level overrides first, then falls back to globals_get()
which reads the value configured in php.ini / .htaccess / per-virtualhost.
set() stores the value in the PHP-level overrides array only. It does NOT
call globals_set(), so the change is confined to this static state and never
modifies the underlying C struct. This prevents settings changed by one
project from leaking into another project sharing the same PHP worker process.
NOTE: In non-ZTS (non-thread-safe) PHP builds, globals_get() reads from a
process-level C struct. Because set() does not write to that struct, any
value set via ini_set("phalcon.orm.*", ...) or globals_set() by other code
remains visible through get() as the fallback for keys that have no
PHP-level override. In ZTS builds each thread has its own copy of the struct.
reset() clears only the keys that were previously set via set(), restoring
those keys to their globals_get() fallback values.
- **`Phalcon\Support\Settings`**
### Method Summary
- `public get(string $key): mixed` — Returns the value of a known setting.
- `public reset(): void` — Clears all PHP-level overrides, restoring get() to return globals\_get()
- `public set(string $key, mixed $value): void` — Overrides a setting at the PHP level.
### Properties
- `protected array $overrides = []` — PHP-level overrides. Keys stored here take priority over globals\_get().
### Methods
get()
```php
public static function get( string $key ): mixed;
```
Returns the value of a known setting.
Resolution order:
1. PHP-level override (set via Settings::set())
2. globals_get() - the C-level value, honoring php.ini / .htaccess
3. null - for unknown keys
reset()
```php
public static function reset(): void;
```
Clears all PHP-level overrides, restoring get() to return globals_get()
fallback values (as configured in php.ini or .htaccess).
set()
```php
public static function set(
string $key,
mixed $value
): void;
```
Overrides a setting at the PHP level.
Does NOT call globals_set(), so the C-level struct is not modified and
no other project sharing this PHP process is affected.
Unknown keys are silently ignored.
## Support\Version
Class
This class allows to get the installed version of the framework
- **`Phalcon\Support\Version`**
### Method Summary
- `public get(): string` — Returns the active version (string)
- `public getId(): string` — Returns the numeric active version
- `public getPart(int $part): string` — Returns a specific part of the version. If the wrong parameter is passed
- `protected getSpecial(int $special): string` — Translates a number to a special release.
- `protected getVersion(): array` — Area where the version number is set. The format is as follows:
### Constants
- `const int VERSION_MAJOR = 0` — The constant referencing the major version. Returns 0
```php
echo (new Phalcon\Support\Version())
->getPart(Phalcon\Support\Version::VERSION_MAJOR);
```
- `const int VERSION_MEDIUM = 1` — The constant referencing the major version. Returns 1
```php
echo (new Phalcon\Support\Version())
->getPart(Phalcon\Support\Version::VERSION_MEDIUM);
```
- `const int VERSION_MINOR = 2` — The constant referencing the major version. Returns 2
```php
echo (new Phalcon\Support\Version())
->getPart(Phalcon\Support\Version::VERSION_MINOR);
```
- `const int VERSION_SPECIAL = 3` — The constant referencing the major version. Returns 3
```php
echo (new Phalcon\Support\Version())
->getPart(Phalcon\Support\Version::VERSION_SPECIAL);
```
- `const int VERSION_SPECIAL_NUMBER = 4` — The constant referencing the major version. Returns 4
```php
echo (new Phalcon\Support\Version())
->getPart(Phalcon\Support\Version::VERSION_SPECIAL_NUMBER);
```
### Methods

```
getSpecial()
```php
final protected function getSpecial( int $special ): string;
```
Translates a number to a special release.
getVersion()
