(After solving the issue mentioned by "num8er" - calling method with () ...)

Try to give an absolute include path

<?php include('/complete/path/to/class_library.php'); ?>

or set an appropriate include path set_include_path() before. You can use $_SERVER['DOCUMENT_ROOT'] as a base to build a path.

You seems using $padisah -> get_ad but your adam class doesn't have any getter metod so you have to use like 

$padisah -> get_ad();

You can find working example on https://eval.in/591811

In Turkish: get_ad kısmının sonunda parantez açıp, kapatırsan sorun çözülür. Adam class'ının içerisinde getter metodu yok. Yukarıda verdiğim linkte sonundaki parantezle sorunun çözüldüğünü görebilirsin.

this is Your class:

<?php
class adam {
  private $ad;

  public function get_ad() {
    return $this->ad;
  }

  public function set_ad($ad) {
    $this->ad = $ad;
    return $this;
  }
}

and inside of code:

  $phpders = new adam();
  $padishah = new adam();

  $phpders->set_ad('NurlanXP 1');
  $padishah->set_ad('NurlanXP 2');

and usage of get_ad:

echo 'phpdersden gelen: '.$phpders->get_ad().'<br/>';
echo 'padishahdan gelen: '.$padishah->get_ad().'<br/>';
