The ReflectionDocBlock component of phpDocumentor provides a DocBlock parser that is 100% compatible with the PHPDoc standard.
With this component, a library can provide support for annotations via DocBlocks or otherwise retrieve information that is embedded in a DocBlock.
composer require phpdocumentor/reflection-docblock
In order to parse the DocBlock one needs a DocBlockFactory that can be
instantiated using its createInstance factory method like this:
$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.
$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:
// 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
/docs/examplesfolder.
