Aspect-Oriented Framework for PHP ----------------- Go! AOP doesn't require any PECL-extentions, it neither uses any dark magic of Runkit nor evals, the library doesn't use DI-containers. The code with weaved aspects is fully readable and native, it can be easily debugged with XDebug. You can debug either classes or aspects. The main advantage of Go! AOP is that potentially it can be installed in every PHP-application, because you don't have to change the application source code at all. As an example, with the help of 10-20 lines of code we can intercept all the public, protected and static methods in all the classes of application and display the name and the arguments of each method during its execution.

In AOP terms, the execution points are called join points, a particular set of them is called a pointcut and the new behavior that is executed before, after, or "around" a join point is called advice. You can read more about AOP in [Introduction](http://go.aopphp.com/docs/introduction/) section. PHP traits can be used to implement some aspect-like functionality. Requirements ------------ Go! AOP library is developed for PHP 5.4.0 and up, but it can partially work with PHP 5.3.0 code. Note that PHP versions before 5.4 will not work completely, if you try to use aspects for code that uses Late Static Binding (LSB) feature. Go! AOP library will not work with eAccelerator. Known bugs ------------ * Version 5.4.5 of PHP has a [bug #62836 Seg fault or broken object references on unserialize()](https://bugs.php.net/bug.php?id=62836). Class advices will be always broken after unserialize(). * Version 5.4.8 of PHP has a [bug #63481 Segmentation fault caused by unserialize()](https://bugs.php.net/bug.php?id=63481). Interceptors for class can be unserialized incorrectly. * Version 5.4.11 of PHP has a [bug #64070 Inheritance with Traits failed with error](https://bugs.php.net/bug.php?id=64070). Method interception in traits is broken, however DeclareParent advice can be used correctly. Installation ------------ Go! AOP library can be installed with composer. Installation is quite easy: 1. Download the library using composer 2. Create an application aspect kernel 3. Configure the aspect kernel in the front controller 4. Create an aspect 5. Register the aspect in the aspect kernel ### Step 1: Download the library using composer Ask composer to download the Go! AOP library with its dependencies by running the command: ``` bash $ php composer.phar require lisachenko/go-aop-php ``` Composer will install the library to your project's `vendor/lisachenko/go-aop-php` directory. ### Step 2: Create an application aspect kernel The aim of this library is to provide easy AOP integration to your application. Your first step then is to create the `AspectKernel` class for your application. This class will manage all aspects of your application in one place. The library provides base class to make it easier to create your own kernel. To create your application kernel extend the abstract class `Go\Core\AspectKernel` ``` php init(array( 'debug' => true, // use 'false' for production mode // Cache directory 'cacheDir' => __DIR__ . '/path/to/cache/for/aop', // Include paths restricts the directories where aspects should be applied, or empty for all source files 'includePaths' => array( __DIR__ . '/../src/' ) )); ``` ### 4. Create an aspect Aspect is the key element of AOP philosophy. And Go! AOP library just uses simple PHP classes for declaring aspects! Therefore it's possible to use all features of OOP for aspect classes. As an example let's intercept all the methods and display their names: ``` php // Aspect/MonitorAspect.php namespace Aspect; use Go\Aop\Aspect; use Go\Aop\Intercept\FieldAccess; use Go\Aop\Intercept\MethodInvocation; use Go\Lang\Annotation\After; use Go\Lang\Annotation\Before; use Go\Lang\Annotation\Around; use Go\Lang\Annotation\Pointcut; /** * Monitor aspect */ class MonitorAspect implements Aspect { /** * Method that will be called before real method * * @param MethodInvocation $invocation Invocation * @Before("execution(public Example->*(*))") */ public function beforeMethodExecution(MethodInvocation $invocation) { $obj = $invocation->getThis(); echo 'Calling Before Interceptor for method: ', is_object($obj) ? get_class($obj) : $obj, $invocation->getMethod()->isStatic() ? '::' : '->', $invocation->getMethod()->getName(), '()', ' with arguments: ', json_encode($invocation->getArguments()), "
\n"; } } ``` Easy, isn't it? We declared here that we want to install a hook before the execution of all dynamic public methods in the class Example. This is done with the help of annotation `@Before("execution(public Example->*(*))")` Hooks can be of any types, you will see them later. But we doesn't change any code in the class Example! I can feel you astonishment now ) ### 5. Register the aspect in the aspect kernel To register the aspect just add an instance of it in the `configureAop()` method of the kernel: ``` php // app/ApplicationAspectKernel.php use Aspect/MonitorAspect; //... protected function configureAop(AspectContainer $container) { $container->registerAspect(new MonitorAspect()); } //... ``` Now you are ready to use the power of aspects! Feel free to change anything everywhere. If you like this project, you could support it Flattr this project!
