Handling Annotations
====================
There are several different approaches to handling annotations in PHP.
Doctrine Annotations maps docblock annotations to PHP classes. Because
not all docblock annotations are used for metadata purposes a filter is
applied to ignore or skip classes that are not Doctrine annotations.
Take a look at the following code snippet:
.. code-block:: php
namespace MyProject\Entities;
use Doctrine\ORM\Mapping AS ORM;
use Symfony\Component\Validator\Constraints AS Assert;
/**
* @author Benjamin Eberlei
* @ORM\Entity
* @MyProject\Annotations\Foobarable
*/
class User
{
/**
* @ORM\Id @ORM\Column @ORM\GeneratedValue
* @dummy
* @var int
*/
private $id;
/**
* @ORM\Column(type="string")
* @Assert\NotEmpty
* @Assert\Email
* @var string
*/
private $email;
}
In this snippet you can see a variety of different docblock annotations:
- Documentation annotations such as ``@var`` and ``@author``. These
annotations are ignored and never considered for throwing an
exception due to wrongly used annotations.
- Annotations imported through use statements. The statement ``use
Doctrine\ORM\Mapping AS ORM`` makes all classes under that namespace
available as ``@ORM\ClassName``. Same goes for the import of
``@Assert``.
- The ``@dummy`` annotation. It is not a documentation annotation and
not ignored. For Doctrine Annotations it is not entirely clear how
to handle this annotation. Depending on the configuration an exception
(unknown annotation) will be thrown when parsing this annotation.
- The fully qualified annotation ``@MyProject\Annotations\Foobarable``.
This is transformed directly into the given class name.
How are these annotations loaded? From looking at the code you could
guess that the ORM Mapping, Assert Validation and the fully qualified
annotation can just be loaded using
the defined PHP autoloaders. This is not the case however: For error
handling reasons every check for class existence inside the
``AnnotationReader`` sets the second parameter $autoload
of ``class_exists($name, $autoload)`` to false. To work flawlessly the
``AnnotationReader`` requires silent autoloaders which many autoloaders are
not. Silent autoloading is NOT part of the `PSR-0 specification
<https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-0.md>`_
for autoloading.
This is why Doctrine Annotations uses its own autoloading mechanism
through a global registry. If you are wondering about the annotation
registry being global, there is no other way to solve the architectural
problems of autoloading annotation classes in a straightforward fashion.
Additionally if you think about PHP autoloading then you recognize it is
a global as well.
To anticipate the configuration section, making the above PHP class work
with Doctrine Annotations requires this setup:
.. code-block:: php
use Doctrine\Common\Annotations\AnnotationReader;
use Doctrine\Common\Annotations\AnnotationRegistry;
AnnotationRegistry::registerFile("/path/to/doctrine/lib/Doctrine/ORM/Mapping/Driver/DoctrineAnnotations.php");
AnnotationRegistry::registerAutoloadNamespace("Symfony\Component\Validator\Constraint", "/path/to/symfony/src");
AnnotationRegistry::registerAutoloadNamespace("MyProject\Annotations", "/path/to/myproject/src");
$reader = new AnnotationReader();
AnnotationReader::addGlobalIgnoredName('dummy');
The second block with the annotation registry calls registers all the
three different annotation namespaces that are used.
Doctrine Annotations saves all its annotations in a single file, that is
why ``AnnotationRegistry#registerFile`` is used in contrast to
``AnnotationRegistry#registerAutoloadNamespace`` which creates a PSR-0
compatible loading mechanism for class to file names.
In the third block, we create the actual ``AnnotationReader`` instance.
Note that we also add ``dummy`` to the global list of ignored
annotations for which we do not throw exceptions. Setting this is
necessary in our example case, otherwise ``@dummy`` would trigger an
exception to be thrown during the parsing of the docblock of
``MyProject\Entities\User#id``.
Setup and Configuration
-----------------------
To use the annotations library is simple, you just need to create a new
``AnnotationReader`` instance:
.. code-block:: php
$reader = new \Doctrine\Common\Annotations\AnnotationReader();
This creates a simple annotation reader with no caching other than in
memory (in php arrays). Since parsing docblocks can be expensive you
should cache this process by using a caching reader.
To cache annotations, you can create a ``Doctrine\Common\Annotations\PsrCachedReader``.
This reader decorates the original reader and stores all annotations in a PSR-6
cache:
.. code-block:: php
use Doctrine\Common\Annotations\AnnotationReader;
use Doctrine\Common\Annotations\PsrCachedReader;
$cache = ... // instantiate a PSR-6 Cache pool
$reader = new PsrCachedReader(
new AnnotationReader(),
$cache,
$debug = true
);
The ``debug`` flag is used here as well to invalidate the cache files
when the PHP class with annotations changed and should be used during
development.
.. warning ::
The ``AnnotationReader`` works and caches under the
assumption that all annotations of a doc-block are processed at
once. That means that annotation classes that do not exist and
aren't loaded and cannot be autoloaded (using the
AnnotationRegistry) would never be visible and not accessible if a
cache is used unless the cache is cleared and the annotations
requested again, this time with all annotations defined.
By default the annotation reader returns a list of annotations with
numeric indexes. If you want your annotations to be indexed by their
class name you can wrap the reader in an ``IndexedReader``:
.. code-block:: php
use Doctrine\Common\Annotations\AnnotationReader;
use Doctrine\Common\Annotations\IndexedReader;
$reader = new IndexedReader(new AnnotationReader());
.. warning::
You should never wrap the indexed reader inside a cached reader,
only the other way around. This way you can re-use the cache with
indexed or numeric keys, otherwise your code may experience failures
due to caching in a numerical or indexed format.
Registering Annotations
~~~~~~~~~~~~~~~~~~~~~~~
As explained in the introduction, Doctrine Annotations uses its own
autoloading mechanism to determine if a given annotation has a
corresponding PHP class that can be autoloaded. For annotation
autoloading you have to configure the
``Doctrine\Common\Annotations\AnnotationRegistry``. There are three
different mechanisms to configure annotation autoloading:
- Calling ``AnnotationRegistry#registerFile($file)`` to register a file
that contains one or more annotation classes.
- Calling ``AnnotationRegistry#registerNamespace($namespace, $dirs =
null)`` to register that the given namespace contains annotations and
that their base directory is located at the given $dirs or in the
include path if ``NULL`` is passed. The given directories should *NOT*
be the directory where classes of the namespace are in, but the base
directory of the root namespace. The AnnotationRegistry uses a
namespace to directory separator approach to resolve the correct path.
- Calling ``AnnotationRegistry#registerLoader($callable)`` to register
an autoloader callback. The callback accepts the class as first and
only parameter and has to return ``true`` if the corresponding file
was found and included.
.. note::
Loaders have to fail silently, if a class is not found even if it
matches for example the namespace prefix of that loader. Never is a
loader to throw a warning or exception if the loading failed
otherwise parsing doc block annotations will become a huge pain.
A sample loader callback could look like:
.. code-block:: php
use Doctrine\Common\Annotations\AnnotationRegistry;
use Symfony\Component\ClassLoader\UniversalClassLoader;
AnnotationRegistry::registerLoader(function($class) {
$file = str_replace("\\", DIRECTORY_SEPARATOR, $class) . ".php";
if (file_exists("/my/base/path/" . $file)) {
// file_exists() makes sure that the loader fails silently
require "/my/base/path/" . $file;
}
});
$loader = new UniversalClassLoader();
AnnotationRegistry::registerLoader(array($loader, "loadClass"));
Ignoring missing exceptions
~~~~~~~~~~~~~~~~~~~~~~~~~~~
By default an exception is thrown from the ``AnnotationReader`` if an
annotation was found that:
- is not part of the list of ignored "documentation annotations";
- was not imported through a use statement;
- is not a fully qualified class that exists.
You can disable this behavior for specific names if your docblocks do
not follow strict requirements:
.. code-block:: php
$reader = new \Doctrine\Common\Annotations\AnnotationReader();
AnnotationReader::addGlobalIgnoredName('foo');
PHP Imports
~~~~~~~~~~~
By default the annotation reader parses the use-statement of a php file
to gain access to the import rules and register them for the annotation
processing. Only if you are using PHP Imports can you validate the
correct usage of annotations and throw exceptions if you misspelled an
annotation. This mechanism is enabled by default.
To ease the upgrade path, we still allow you to disable this mechanism.
Note however that we will remove this in future versions:
.. code-block:: php
$reader = new \Doctrine\Common\Annotations\AnnotationReader();
$reader->setEnabledPhpImports(false);

Custom Annotation Classes
=========================
If you want to define your own annotations, you just have to group them
in a namespace and register this namespace in the ``AnnotationRegistry``.
Annotation classes have to contain a class-level docblock with the text
``@Annotation``:
.. code-block:: php
namespace MyCompany\Annotations;
/** @Annotation */
class Bar
{
// some code
}
Inject annotation values
------------------------
The annotation parser checks if the annotation constructor has arguments,
if so then it will pass the value array, otherwise it will try to inject
values into public properties directly:
.. code-block:: php
namespace MyCompany\Annotations;
/**
* @Annotation
*
* Some Annotation using a constructor
*/
class Bar
{
private $foo;
public function __construct(array $values)
{
$this->foo = $values['foo'];
}
}
/**
* @Annotation
*
* Some Annotation without a constructor
*/
class Foo
{
public $bar;
}
Optional: Constructors with Named Parameters
--------------------------------------------
Starting with Annotations v1.11 a new annotation instantiation strategy
is available that aims at compatibility of Annotation classes with the PHP 8
attribute feature. You need to declare a constructor with regular parameter
names that match the named arguments in the annotation syntax.
To enable this feature, you can tag your annotation class with
``@NamedArgumentConstructor`` (available from v1.12) or implement the
``Doctrine\Common\Annotations\NamedArgumentConstructorAnnotation`` interface
(available from v1.11 and deprecated as of v1.12).
When using the ``@NamedArgumentConstructor`` tag, the first argument of the
constructor is considered as the default one.
Usage with the ``@NamedArgumentContrustor`` tag
.. code-block:: php
namespace MyCompany\Annotations;
/**
* @Annotation
* @NamedArgumentConstructor
*/
class Bar implements NamedArgumentConstructorAnnotation
{
private $foo;
public function __construct(string $foo)
{
$this->foo = $foo;
}
}
/** Usable with @Bar(foo="baz") */
/** Usable with @Bar("baz") */
In combination with PHP 8's constructor property promotion feature
you can simplify this to:
.. code-block:: php
namespace MyCompany\Annotations;
/**
* @Annotation
* @NamedArgumentConstructor
*/
class Bar implements NamedArgumentConstructorAnnotation
{
public function __construct(private string $foo) {}
}
Usage with the
``Doctrine\Common\Annotations\NamedArgumentConstructorAnnotation``
interface (v1.11, deprecated as of v1.12):
.. code-block:: php
namespace MyCompany\Annotations;
use Doctrine\Common\Annotations\NamedArgumentConstructorAnnotation;
/** @Annotation */
class Bar implements NamedArgumentConstructorAnnotation
{
private $foo;
public function __construct(private string $foo) {}
}
/** Usable with @Bar(foo="baz") */
Annotation Target
-----------------
``@Target`` indicates the kinds of class elements to which an annotation
type is applicable. Then you could define one or more targets:
- ``CLASS`` Allowed in class docblocks
- ``PROPERTY`` Allowed in property docblocks
- ``METHOD`` Allowed in the method docblocks
- ``FUNCTION`` Allowed in function dockblocks
- ``ALL`` Allowed in class, property, method and function docblocks
- ``ANNOTATION`` Allowed inside other annotations
If the annotations is not allowed in the current context, an
``AnnotationException`` is thrown.
.. code-block:: php
namespace MyCompany\Annotations;
/**
* @Annotation
* @Target({"METHOD","PROPERTY"})
*/
class Bar
{
// some code
}
/**
* @Annotation
* @Target("CLASS")
*/
class Foo
{
// some code
}
Attribute types
---------------
The annotation parser checks the given parameters using the phpdoc
annotation ``@var``, The data type could be validated using the ``@var``
annotation on the annotation properties or using the ``@Attributes`` and
``@Attribute`` annotations.
If the data type does not match you get an ``AnnotationException``
.. code-block:: php
namespace MyCompany\Annotations;
/**
* @Annotation
* @Target({"METHOD","PROPERTY"})
*/
class Bar
{
/** @var mixed */
public $mixed;
/** @var boolean */
public $boolean;
/** @var bool */
public $bool;
/** @var float */
public $float;
/** @var string */
public $string;
/** @var integer */
public $integer;
/** @var array */
public $array;
/** @var SomeAnnotationClass */
public $annotation;
/** @var array<integer> */
public $arrayOfIntegers;
/** @var array<SomeAnnotationClass> */
public $arrayOfAnnotations;
}
/**
* @Annotation
* @Target({"METHOD","PROPERTY"})
* @Attributes({
* @Attribute("stringProperty", type = "string"),
* @Attribute("annotProperty", type = "SomeAnnotationClass"),
* })
*/
class Foo
{
public function __construct(array $values)
{
$this->stringProperty = $values['stringProperty'];
$this->annotProperty = $values['annotProperty'];
}
// some code
}
Annotation Required
-------------------
``@Required`` indicates that the field must be specified when the
annotation is used. If it is not used you get an ``AnnotationException``
stating that this value can not be null.
Declaring a required field:
.. code-block:: php
/**
* @Annotation
* @Target("ALL")
*/
class Foo
{
/** @Required */
public $requiredField;
}
Usage:
.. code-block:: php
/** @Foo(requiredField="value") */
public $direction; // Valid
/** @Foo */
public $direction; // Required field missing, throws an AnnotationException
Enumerated values
-----------------
- An annotation property marked with ``@Enum`` is a field that accepts a
fixed set of scalar values.
- You should use ``@Enum`` fields any time you need to represent fixed
values.
- The annotation parser checks the given value and throws an
``AnnotationException`` if the value does not match.
Declaring an enumerated property:
.. code-block:: php
/**
* @Annotation
* @Target("ALL")
*/
class Direction
{
/**
* @Enum({"NORTH", "SOUTH", "EAST", "WEST"})
*/
public $value;
}
Annotation usage:
.. code-block:: php
/** @Direction("NORTH") */
public $direction; // Valid value
/** @Direction("NORTHEAST") */
public $direction; // Invalid value, throws an AnnotationException
Constants
---------
The use of constants and class constants is available on the annotations
parser.
The following usages are allowed:
.. code-block:: php
namespace MyCompany\Entity;
use MyCompany\Annotations\Foo;
use MyCompany\Annotations\Bar;
use MyCompany\Entity\SomeClass;
/**
* @Foo(PHP_EOL)
* @Bar(Bar::FOO)
* @Foo({SomeClass::FOO, SomeClass::BAR})
* @Bar({SomeClass::FOO_KEY = SomeClass::BAR_VALUE})
*/
class User
{
}
Be careful with constants and the cache !
.. note::
The cached reader will not re-evaluate each time an annotation is
loaded from cache. When a constant is changed the cache must be
cleaned.
Usage
-----
Using the library API is simple. Using the annotations described in the
previous section, you can now annotate other classes with your
annotations:
.. code-block:: php
namespace MyCompany\Entity;
use MyCompany\Annotations\Foo;
use MyCompany\Annotations\Bar;
/**
* @Foo(bar="foo")
* @Bar(foo="bar")
*/
class User
{
}
Now we can write a script to get the annotations above:
.. code-block:: php
$reflClass = new ReflectionClass('MyCompany\Entity\User');
$classAnnotations = $reader->getClassAnnotations($reflClass);
foreach ($classAnnotations AS $annot) {
if ($annot instanceof \MyCompany\Annotations\Foo) {
echo $annot->bar; // prints "foo";
} else if ($annot instanceof \MyCompany\Annotations\Bar) {
echo $annot->foo; // prints "bar";
}
}
You have a complete API for retrieving annotation class instances from a
class, property or method docblock:

Introduction
============
Doctrine Annotations allows to implement custom annotation
functionality for PHP classes and functions.
.. code-block:: php
class Foo
{
/**
* @MyAnnotation(myProperty="value")
*/
private $bar;
}
Annotations aren't implemented in PHP itself which is why this component
offers a way to use the PHP doc-blocks as a place for the well known
annotation syntax using the ``@`` char.
Annotations in Doctrine are used for the ORM configuration to build the
class mapping, but it can be used in other projects for other purposes
too.
Installation
============
You can install the Annotation component with composer:
.. code-block::
  $ composer require doctrine/annotations
Create an annotation class
==========================
An annotation class is a representation of the later used annotation
configuration in classes. The annotation class of the previous example
looks like this:
.. code-block:: php
/**
* @Annotation
*/
final class MyAnnotation
{
public $myProperty;
}
The annotation class is declared as an annotation by ``@Annotation``.
:ref:`Read more about custom annotations. <custom>`
Reading annotations
===================
The access to the annotations happens by reflection of the class or function
containing them. There are multiple reader-classes implementing the
``Doctrine\Common\Annotations\Reader`` interface, that can access the
annotations of a class. A common one is
``Doctrine\Common\Annotations\AnnotationReader``:
.. code-block:: php
use Doctrine\Common\Annotations\AnnotationReader;
use Doctrine\Common\Annotations\AnnotationRegistry;
// Deprecated and will be removed in 2.0 but currently needed
AnnotationRegistry::registerLoader('class_exists');
$reflectionClass = new ReflectionClass(Foo::class);
$property = $reflectionClass->getProperty('bar');
$reader = new AnnotationReader();
$myAnnotation = $reader->getPropertyAnnotation(
$property,
MyAnnotation::class
);
echo $myAnnotation->myProperty; // result: "value"
Note that ``AnnotationRegistry::registerLoader('class_exists')`` only works
if you already have an autoloader configured (i.e. composer autoloader).
Otherwise, :ref:`please take a look to the other annotation autoload mechanisms <annotations>`.
A reader has multiple methods to access the annotations of a class or
function.
:ref:`Read more about handling annotations. <annotations>`
IDE Support
-----------
Some IDEs already provide support for annotations:
- Eclipse via the `Symfony2 Plugin <https://github.com/pulse00/Symfony-2-Eclipse-Plugin>`_
- PhpStorm via the `PHP Annotations Plugin <https://plugins.jetbrains.com/plugin/7320-php-annotations>`_ or the `Symfony Plugin <https://plugins.jetbrains.com/plugin/7219-symfony-support>`_
