[Solved] Php Calculating two functions [closed]

by


You can’t access $dine in your second function because it’s nowhere defined. The $dine from your first function is only a local variable.

I would suggest this solution which uses the fact that calculate_dinein_price() also returns the value of $dine:

public function calculate_dinein_total(){
    $total_dine = 0.00;
    $total_dine = $total_dine + $this->calculate_dinein_price();

    return $total_dine;
}
