<? //PHP5.X
/*
Dynamically load objects
Here is how you can inherit all methods from
any of your Classes without having to use extended.
Therefore, you can create multiple inheritance
in PHP sort of like C++.
*/
// If the Generic Classes were located in different
// files and if you name your files after your classes
// i.e. Class1.php - Class2.php - Class3.php
// use the autoload function
if(!function_exists("__autoload")){
function __autoload($classname)
{
require_once $classname . '.php';
}
}
//Take a look at Class3
////////////// Begin Generic Classes /////////////////////
class Class1 {
public function doSomething(){
echo "<br />doSomething() in ".get_class($this);
}
public function doSomethingElse(){
echo "<br />doSomethingElse() in ".get_class($this);
}
} // end class Class1
class Class2 {
public function doSomethingDiff(){
echo "<br />doSomethingDiff() in ".get_class($this);
}
} // end class Class2
class Class3 {
public function doThisThing(Class1 $obj){
echo get_class($this);
echo " calling... ";
echo $obj->doSomething(); // call Class1 method
}
} // end class Class3
//////////////// End Generic Classes ////////////////////
//////////////// Begin MultiInherit Class ///////////////
/*
The class MultiInherit is the key to this working.
This could be more dynamic if you prefer, but
keep in mind that runtime errors are less likely
using single inheritance.
*/
class MultiInherit {
public $obj = array();//create class variable type array
public function setObj(array $obj){ // type hinting
$this->obj = $obj;

EXPECTED OUTPUT:
