Installation.

composer require thenlabs/meta-parser dev-main

Usage example.

/**
 * @MyMetadata(data1="value1")
 */
#[MyMetadata(data1: 'value2')]
class MyClass
{
}

$myClass = new ReflectionClass(MyClass::class);

/**
 * Reading from annotations only.
 */
$annotationParser = new ThenLabs\MetaParser\AnnotationParser();
$annotationParserResult = $annotationParser->parse($myClass);

$annotationParserResult->get(MyMetadata::class)->get('data1') === 'value1'; // true

/**
 * Reading from attributes only.
 */
$attributeParser = new ThenLabs\MetaParser\AttributeParser();
$attributeParserResult = $attributeParser->parse($myClass);

$attributeParserResult->get(MyMetadata::class)->get('data1') === 'value2'; // true

/**
 * Reading both.
 */
$parser = new ThenLabs\MetaParser\Parser();
$parserResult = $parser->parse($myClass);

// this returns true becouse attributes override annotations.
$parserResult->get(MyMetadata::class)->get('data1') === 'value2';

Highlights about ThenLabs\MetaParser\Parser class.

1. For read annotations it's necessary to install Doctrine Annotations:

$ composer require doctrine/annotations

2. The attribute parser require a PHP version grater than 8.0.

3. The parse() methods accept an instance of Reflector, so that, for parse a method of a class(for example), you can use a ReflectionMethod instance.
