The ReflectionDocBlock Component [](https://travis-ci.org/phpDocumentor/ReflectionDocBlock) ================================ Introduction ------------ The ReflectionDocBlock component of phpDocumentor provides a DocBlock parser that is 100% compatible with the [PHPDoc standard](http://phpdoc.org/docs/latest). With this component, a library can provide support for annotations via DocBlocks or otherwise retrieve information that is embedded in a DocBlock. Installation ------------ ```bash composer require phpdocumentor/reflection-docblock ``` Usage ----- In order to parse the DocBlock one needs a DocBlockFactory that can be instantiated using its `createInstance` factory method like this: ```php $factory = \phpDocumentor\Reflection\DocBlockFactory::createInstance(); ``` Then we can use the `create` method of the factory to interpret the DocBlock. Please note that it is also possible to provide a class that has the `getDocComment()` method, such as an object of type `ReflectionClass`, the create method will read that if it exists. ```php $docComment = <<<DOCCOMMENT /** * This is an example of a summary. * * This is a Description. A Summary and Description are separated by either * two subsequent newlines (thus a whiteline in between as can be seen in this * example), or when the Summary ends with a dot (`.`) and some form of * whitespace. */ DOCCOMMENT; $docblock = $factory->create($docComment); ``` The `create` method will yield an object of type `\phpDocumentor\Reflection\DocBlock` whose methods can be queried: ```php // Contains the summary for this DocBlock $summary = $docblock->getSummary(); // Contains \phpDocumentor\Reflection\DocBlock\Description object $description = $docblock->getDescription(); // You can either cast it to string $description = (string) $docblock->getDescription(); // Or use the render method to get a string representation of the Description. $description = $docblock->getDescription()->render(); ``` > For more examples it would be best to review the scripts in the [`/examples` folder](/examples).
