	public function setMyPrivateValues( $arrData ){
		foreach( $arrData as $strKey => $mixValue ){ $this->$strKey = $mixValue; }
	}

$arrData = array( 'strName' => 'jonh' );
$objChild2 = new childClass2();	// If i rewrite the method
$objChild2->setMyPrivateValues( $arrData ); // Set a private attribute
