Hide price if set to 0€

Hello,

Is it possible to hide price if value is 0€ ?

i have try something like this :

<td class="price"><?php $price = $item['order_price']; if($price == '0' ) { echo '-'; } else { echo $price; } ?></td>

with replacing 0 by 0,00 0.00 and with or without € symbol, it always display 0,00€.
