Answer 1

You are overriding the constructor, so you have to call parent constructor with expected signature, like parent::__construct(); on top of your constructor function:

public function __construct($orientation = 'P', $unit = 'pt', $format = 'Letter', $margin = 40)
{
    parent::__construct($orientation, $unit, $format, $margin);
    //$this->FPDF($orientation, $unit, $format);
    $this->SetTopMargin($margin);
    $this->SetLeftMargin($margin);
    $this->SetRightMargin($margin);
    $this->SetAutoPageBreak(true, $margin);
}

Also all functions within your class should be declared with access modifier (public, private etc.)
