I would like to have a base class with basic properties and functions, so I dont have to define them in all child classes.
I use php 5.3.3.

Bu imkansız mı?

class A {
  private $debug;
  private $var;
  protected function setVar($str) {
    $this->debug = 'Set by function `'. MAGIC_HERE .'` in class `'. get_called_class() .'`.';
    $this->var = $str;
    return true;
  }
  protected function getVar() {
    return $this->var;
  }
  protected function getDebug() {
    return $this->debug;
  }
}
class B extends A {
  public function __construct() {
    $this->doSomething();
  }
  public function doSomething() {
    $this->setVar('my string');
  }
}
$myobj = new B();
$myobj->getDebug();
// expected output "Set by function `doSomething` in class `B`."
