Phalcon acl

Acl\AbstractElement¶

Abstract Source on GitHub

Shared base for ACL Role and Component entities: a name and an optional description.

@todo Remove in v7. Kept only for backwards compatibility; the logic now lives in Phalcon\Acl\Traits\ItemTrait - compose that trait directly instead of extending this class.

Method Summary¶

Properties¶

Methods¶

__construct()¶

public function __construct();

Phalcon\Acl\Adapter\Memory constructor

addComponent()¶

public function addComponent(
    mixed $componentValue,
    mixed $accessList
): bool;

Adds a component to the ACL list

Access names can be a particular action, by example search, update, delete, etc. or a list of them

Example:

// Add a component to the list allowing access to an action
$acl->addComponent(
    new Phalcon\Acl\Component("customers"),
    "search"
);

$acl->addComponent("customers", "search");

// Add a component  with an access list
$acl->addComponent(
    new Phalcon\Acl\Component("customers"),
    [
        "create",
        "search",
    ]
);

$acl->addComponent(
    "customers",
    [
        "create",
        "search",
    ]
);

addComponentAccess()¶

public function addComponentAccess(
    string $componentName,
    mixed $accessList
): bool;

Adds access to components

addInherit()¶

public function addInherit(
    string $roleName,
    mixed $roleToInherits
): bool;

Do a role inherit from another existing role

$acl->addRole("administrator", "consultant");
$acl->addRole("administrator", ["consultant", "consultant2"]);

addRole()¶

public function addRole(
    mixed $role,
    mixed $accessInherits = null
): bool;

Adds a role to the ACL list. Second parameter allows inheriting access data from other existing role

If the role already exists this method returns false and the accessInherits argument is ignored; the existing role is left unchanged.

$acl->addRole(
    new Phalcon\Acl\Role("administrator"),
    "consultant"
);

$acl->addRole("administrator", "consultant");
$acl->addRole("administrator", ["consultant", "consultant2"]);

allow()¶

public function allow(
    string $roleName,
    string $componentName,
    mixed $access,
    mixed $func = null
): void;

Allow access to a role on a component. You can use * as wildcard

A * role is an eager snapshot: it expands to the roles that exist when allow() is called, so roles added afterwards do not inherit the grant.

// Allow access to guests to search on customers
$acl->allow("guests", "customers", "search");

// Allow access to guests to search or create on customers
$acl->allow("guests", "customers", ["search", "create"]);

// Allow access to any role to browse on products
$acl->allow("*", "products", "browse");

// Allow access to any role to perform any action on any component
$acl->allow("*", "*", "*");

deny()¶

public function deny(
    string $roleName,
    string $componentName,
    mixed $access,
    mixed $func = null
): void;

Deny access to a role on a component. You can use * as wildcard

A * role is an eager snapshot: it expands to the roles that exist when deny() is called, so roles added afterwards do not inherit the rule.

// Deny access to guests to search on customers
$acl->deny("guests", "customers", "search");

// Deny access to guests to search or create on customers
$acl->deny("guests", "customers", ["search", "create"]);

// Deny access to any role to browse on products
$acl->deny("*", "products", "browse");

// Deny access to any role to perform any action on any component
$acl->deny("*", "*", "*");

public function dropComponentAccess(
    string $componentName,
    mixed $accessList
): void;

Removes access from a component

getInheritedRoles()¶

public function getInheritedRoles( string $roleName = "" ): array;

Returns the inherited roles for a passed role name. If no role name has been specified it will return the whole array. If the role has not been found it returns an empty array

getNoArgumentsDefaultAction()¶

public function getNoArgumentsDefaultAction(): int;

Returns the default ACL access level for no arguments provided in isAllowed action if a func (callable) exists for accessKey

getRoles()¶

public function getRoles(): RoleInterface[];

isAllowed()¶

public function isAllowed(
    mixed $roleName,
    mixed $componentName,
    string $access,
    array $parameters = null
): bool;

Check whether a role is allowed to access an action from a component

// Does andres have access to the customers component to create?
$acl->isAllowed("andres", "Products", "create");

// Do guests have access to any component to edit?
$acl->isAllowed("guests", "*", "edit");

isComponent()¶

public function isComponent( string $componentName ): bool;

Check whether component exist in the components list

isRole()¶

public function isRole( string $roleName ): bool;

Check whether role exist in the roles list

setNoArgumentsDefaultAction()¶

public function setNoArgumentsDefaultAction( int $defaultAccess ): void;

Sets the default access level (Phalcon\Enum::ALLOW or Phalcon\Enum::DENY) for no arguments provided in isAllowed action if there exists func for accessKey

Acl\Adapter\Storage¶

Class Source on GitHub

ACL adapter that persists its policy to any Phalcon\Storage backend (Redis, Apcu, Stream, Memcached, ...) as a whole-policy snapshot.

The snapshot is a versioned, scalar-only structure: roles and components are stored as name => description maps and rebuilt into objects on load, so the snapshot round-trips through any serializer (php, json, igbinary, msgpack).

Callable (closure) rules are not serializable. Any access key backed by a closure is persisted as DENY, so a reloaded policy fails closed until the closure is re-registered after load().

Single-writer contract: mutations are in-memory until save() is called, and save() writes the whole snapshot (last-write-wins, no atomic check-and-set). Use external locking when multiple processes write the same key.

Methods¶

__construct()¶

public function __construct(
    StorageInterface $storage,
    string $key = "acl-data"
);

load()¶

public function load(): bool;

Loads the policy snapshot from the backing store, replacing current in-memory state. Returns false when no compatible snapshot exists; throws Phalcon\Acl\Exceptions\InvalidSnapshot on an incompatible version or a malformed structure.

save()¶

public function save(): bool;

Persists the policy snapshot. Closure-backed access keys are written as DENY (fail closed); roles/components are written as scalar name => description maps for serializer independence.
