$property = new ReflectionProperty('Basket', 'apple');
$attributes = $property->getAttributes();

Örnek 2 Filtering results by class name
<?php

<?php

class Basket {

#[Red]
public string $apple = 'apple';
}
$property = new ReflectionProperty('Basket', 'apple');
$attributes = $property->getAttributes('Color', ReflectionAttribute::IS_INSTANCEOF);
print_r(array_map(fn($attribute) => $attribute->getName(), $attributes));
?>Yukarıdaki örneğin çıktısı:
Array
(
[0] => Red
)
