How could I get the price of the product in php?

$config =& hikashop_config();
		$currencyClass = hikashop_get('class.currency');
		$main_currency = $currency_id = (int)$config->get('main_currency',1);
	 	$zone_id = explode(',',$config->get('main_tax_zone',0));

		if(count($zone_id)){
			$zone_id = array_shift($zone_id);
		}else{
			$zone_id=0;
		}
		$ids = array($product->product_id);
		$discount_before_tax = (int)$config->get('discount_before_tax',0);
		$currencyClass->getPrices($product,$ids,$currency_id,$main_currency,$zone_id,$discount_before_tax);
