ReflectionFunctionAbstract::getAttributes — Gets Attributes
Returns all attributes declared on this function or method as an array of ReflectionAttribute.
nameFilter the results to include only ReflectionAttribute instances for attributes matching this class name.
flags
Flags for determining how to filter the results, if name
is provided.
Default is 0 which will only return results for attributes that
are of the class name.
The only other option available, is to use ReflectionAttribute::IS_INSTANCEOF,
which will instead use instanceof for filtering.
Array of attributes, as a ReflectionAttribute object.
Örnek 1 Basic usage with a class method
<?php
#[Attribute]
class Fruit {
}
#[Attribute]
class Red {
}
class Factory {
#[Fruit]
#[Red]
public function makeApple(): string
{
return 'apple';
}
}
$method = new ReflectionMethod('Factory', 'makeApple');
$attributes = $method->getAttributes();
print_r(array_map(fn($attribute) => $attribute->getName(), $attributes));
?>Yukarıdaki örneğin çıktısı:
Array
(
[0] => Fruit
[1] => Red
)
Örnek 2 Basic usage with a function
<?php
#[Attribute]
class Fruit {
}
#[Attribute]
class Red {
}
#[Fruit]
#[Red]
function makeApple(): string
{
return 'apple';
}
$function = new ReflectionFunction('makeApple');
$attributes = $function->getAttributes();
print_r(array_map(fn($attribute) => $attribute->getName(), $attributes));
?>Yukarıdaki örneğin çıktısı:
Array
(
[0] => Fruit
[1] => Red
)
Örnek 3 Filtering results by class name
<?php
#[Attribute]
class Fruit {
}
#[Attribute]
class Red {
}
#[Fruit]
#[Red]
function makeApple(): string
{
return 'apple';
}
$function = new ReflectionFunction('makeApple');
$attributes = $function->getAttributes('Fruit');
print_r(array_map(fn($attribute) => $attribute->getName(), $attributes));
?>Yukarıdaki örneğin çıktısı:
Array
(
[0] => Fruit
)
Örnek 4 Filtering results by class name, with inheritance
<?php
interface Color {
}
#[Attribute]
class Fruit {
}
#[Attribute]
class Red implements Color {
}
#[Fruit]
#[Red]
function makeApple(): string
{
return 'apple';
}
$function = new ReflectionFunction('makeApple');
$attributes = $function->getAttributes('Color', ReflectionAttribute::IS_INSTANCEOF);
print_r(array_map(fn($attribute) => $attribute->getName(), $attributes));
?>Yukarıdaki örneğin çıktısı:
Array
(
[0] => Red
)
