POIs it possible to modify methods of an object instance using reflection
text
Body
copied!<p>What I'm trying to do is create a domain model with a Plain Old PHP Object. The I'm creating a library which will do all the infrastructure stuff. So one of my models looks like this</p> <pre><code>class Project { public $id; public $name; public $typeId; private $type; public function getType() { return $this->type; } public function setType(Type $type) { $this->typeId = $type->id; $this->type = $type; } } </code></pre> <p>Now if create a new Project and call <code>setType</code> with a valid Type object and save the project instance using the ORM both the project and type is saved. But then I load the Project and use <code>getType</code> method I want the ORM to have modified this method transparently to load the object from persitence. So this method here:</p> <pre><code>public function getType() { return $this->type; } </code></pre> <p>to be transparently changed into:</p> <pre><code>public function getType() { if (is_null($this->type) { $this->type = $this->adapter->findById('table', $this->typeId); } return $this->type; // or return parent::getType(); } </code></pre> <p>Outlet PHP uses eval to create a Proxy class for Project called Project_Proxy but sometimes there will be subclasses of Project so I am searching for a solution by using Reflection API if there is a way.</p> <p>I have search google but haven't found anyway to change a method behaviour</p> <p><strong>Edit:</strong> or would it be a good idea to use Outlet PHP's eval method to create Proxy Classes for my models and all subclasses of them?</p>
