      I'd do it like this:

      class A {

      }

      class B {
      private $my_object;
      public function __construct(){
      $this->my_object = new A();
      }
      }

              New Question

              if i like to use the instance from other method into the class how can
              i do that ? ? ?

              example:

              class class_a
              {
              public function method_a()
              {

              }
              }

              class class_b
              {
              private $objInstance;

              public function __construct()
              {
              $this->objInstance = new class_a();
              }

              public function method_t()
              {
              how to use the $objInstance methods into this method ? ? ?
              }
              }

                  You can use objInstance methods like that :
                  class class_b
                  {
                  private $objInstance;

                  public function __construct()
                  {
                  $this->objInstance = new class_a();
                  }

                  public function method_t()
                  {
                  $this->objInstance->method();
                  }
                  }

                      This way it works but only into the constructor method.

                      I have try to use ot in other methods in the class and doesn't work ! !
                      ! ? ? ?

                              Nope.

                              Post your code.

                                  Hello!

                                  I'm a PHP newbie, but I've been busy writing much OO-Code over the last
                                  years.
                                  I had an idea solving this problem using the following scheme:

                                  class A
                                  {
                                  public function methodA(){
                                  //some useful code
                                  }
                                  class B
                                  {
                                  private A $instanceOfA; //but I am really not sure if this one's works

                                  public __construct() {
                                  $instanceOfA=ne w A();
                                  }
                                  public function methodB(){
                                  $this->instanceOfA->methodA();
                                  }
                                  }
                                  }
                                  Anyway this is legal in terms of OO-Programming and also a well used
                                  method for composing classes. I tried this out in PHP but it doesn't
                                  seem to work. Obviously you'll have to create the instance within the
                                  function/method you want to use it. Like:

                                  class B
                                  {
                                  //....
                                  public function methodB(){
                                  $instanceOfA=ne w A();
                                  $instanceOfA->methodA();
                                  }
                                  }

                                  Well I ran a test with that and it worked. It's not that elegant but I
                                  think it makes sense...

                                  regards
                                  Kostas

                                      }
                                      }
                                      }

                                      function/method you want to use it. Like:
                                      What you really wanted to do in the constructor of B was the following:

                                      public __construct() {
                                      $this->instanceOfA = new A();
                                      }

                                      Because with $instanceOfA you create a local (in that function) variable...
