My mixin class is causing my classes to become static - PHP - php

Question

So this is my mixin class:
class AisisCore_Loader_Mixins {
private $_classes;
private $_class_objects = array();
private $_methods = array();
public function __construct(){
$this->init();
}
public function init(){}
public function setup($class){
if(!is_array($class)){
throw new AisisCore_Loader_LoaderException('Object passed in must be of type $class_name=>$params.');
}
$this->_classes = $class;
$this->get_class_objects();
$this->get_methods();
}
public function get_class_objects(){
foreach($this->_classes as $class_name=>$params){
$object = new ReflectionClass($class_name);
$object_name = get_class($object);
$this->_class_objects[$object->name] = $object->newInstanceArgs($params);
}
}
public function get_methods(){
foreach($this->_class_objects as $class_object_name => $class_object){
$this->_methods[$class_object_name] = get_class_methods($class_object);
}
return $this->_methods;
}
public function __call($name, $param = null){
foreach($this->_methods as $class_name=>$methods){
foreach($methods as $method){
if($name === $method){
return $this->isParam($class_name, $method, $param);
}
}
}
throw new AisisCore_Loader_LoaderException("Method: " .$name.
" does not exist or it's access is not public");
}
private function isParam($class_name, $method, $param){
if($param != null){
call_user_func(array($class_name, $method), $param);
}else{
call_user_func(array($class_name, $method));
}
}
}
Pretty simple stuff, load a set of classes, allow you to call their functions and so on, but we have a new issue. It seems that classes passed into this are instantiated as static, thus their methods cannot use $this-> they are resorted to using self:: which is wrong.
Lets see an example of how this all works:
class BaseBridge extends AisisCore_Loader_Mixins{
public function __construct(){
parent::construct();
$this->setup(array('ClassB' => array()));
}
}
Lets Define ClassB
class ClassB{
public function __construct(){}
public function some_method(){
$this->_some_private_method();
}
private function _some_private_method(){}
}
Pretty basic stuff, so lets hook it all up in ClassA
class ClassA extends BaseBridge{
public function __construct(){
parent::__construct();
$this->some_method();
}
}
Quick Review: We have a core class, ClassA which extends BaseBridge which is our bridge class between one or more (meant to be used with more) classes that ClassA extends from. In this case were only extending from ClassB for simplicity.
Whats the issue? See, how in ClassB, were doing: $this->_some_private_method(); ya that's going to epically and catastrophically fail. Why? because I get the error: Using $this when not in object context which makes me so confused, so I change it to: self::$_some_private_method(); and it works like a charm.
Why? and what do I have to change or fix to make it so that $this can be used in a class being instantiated through the mixin class?

So with some slight modifications, I have managed to make this work. How ever I do not believe that a function with multiple arguments will work - Feed back appreciated.
class AisisCore_Loader_Mixins {
private $_classes;
private $_class_objects = array();
private $_methods = array();
public function __construct(){
$this->init();
}
public function init(){}
public function setup($class){
if(!is_array($class)){
throw new AisisCore_Loader_LoaderException('Object passed in must be of type $class_name=>$params.');
}
$this->_classes = $class;
$this->get_class_objects();
$this->get_methods();
}
public function get_class_objects(){
foreach($this->_classes as $class_name=>$params){
$object = new ReflectionClass($class_name);
$this->_class_objects[$object->name] = $object->newInstanceArgs($params);
}
}
public function get_methods(){
foreach($this->_class_objects as $class_object_name => $class_object){
$this->_methods[$class_object_name] = get_class_methods($class_object);
}
return $this->_methods;
}
public function __call($name, $param = null){
foreach($this->_methods as $class_name=>$methods){
foreach($methods as $method){
if($name === $method){
return $this->_is_param($class_name, $method, $param);
}
}
}
throw new AisisCore_Loader_LoaderException("Method: " .$name.
" does not exist or it's access is not public");
}
private function _is_param($class_name, $method, $param){
if($param != null){
$this->_param_is_array($class_name, $method, $param);
}else{
call_user_func(array($this->_class_objects[$class_name], $method));
}
}
private function _param_is_array($class_name, $method, $param){
if(is_array($param)){
call_user_func_array(array($this->_class_objects[$class_name], $method), $param);
}else{
call_user_func(array($this->_class_objects[$class_name], $method, $param));
}
}
}
Now functions inside of classes that are registered by this class can use $this->.
The issue is that I am not sure if multiple param based functions will actually work.
