README
This library provides a performance-improved, and convenient way to deal with PHP Reflection classes.
-
Performance: Reflection is slow if you instantiate it continuously. If you rely on reflection heavily to inspect the same type of classes in one request over and over again, then caching of the created Reflection classes helps a lot.
-
Convenience: Instead of dealing with the object graph of Reflection classes, a facade offers convenient methods to
- retrieve PHP Reflection classes,
- getting/setting static and non-static properties of an object or class,
- invoking static and non-static methods of an object or class.
Installation
Use Composer to install this library:
$ composer require scaleupstack/reflection
Usage
The public API of this package is available via the ScaleUpStack\Reflection\Reflection
class. All methods of the Reflection
class are static. (In fact, it is not possible to instantiate it.)
-
Namespace
use ScaleUpStack\Reflection\Reflection;
-
Methods to retrieve PHP Reflection objects via class name or object:
Reflection::classByName(string $className) : \ReflectionClass Reflection::classByObject(object $object) : \ReflectionClass Reflection::propertyOfClass(string $className, string $propertyName) : \ReflectionProperty Reflection::propertyOfObject(object $object, string $propertyName) : \ReflectionProperty Reflection::allPropertiesOfClass(string $className) : \ReflectionProperty[] Reflection::allPropertiesOfObject(object $object) : \ReflectionProperty[] Reflection::methodOfClass(string $className, string $methodName) : \ReflectionMethod Reflection::methodOfObject(object $object, string $methodName) : \ReflectionMethod Reflection::allMethodsOfClass(string $className) : \ReflectionMethod[] Reflection::allMethodsOfObject(object $object) : \ReflectionMethod[]
Please note that
classByObject()
returns a\ReflectionClass
and not a\ReflectionObject
. -
Methods to access static and non-static properties:
Reflection::getPropertyValue(object $object, string $propertyName) : mixed Reflection::getStaticPropertyValue(string $className, string $propertyName) : mixed Reflection::setPropertyValue(object $object, string $propertyName, $value) : void Reflection::setStaticPropertyValue(string $className, string $propertyName, $value) : void
-
Methods to invoke static and non-static methods:
Reflection::invokeMethod(object $object, string $methodName, array $arguments) : mixed Reflection::invokeStaticMethod(string $className, string $methodName, array $arguments) : mixed
Current State
This library is stable.
Handling of some Reflection features that could (perhaps?) benefit from caching (e.g. getting the parent class) are not implemented yet. But I do not strive for completeness. If you are missing some features, just create a pull request or ask for it, explaining your context/needs.
