變化以下行括號：。

$prod_id = $row_pro('prod_id'); 
$prod_name = $row_pro('prod_name'); 
$prod_price = $row_pro('prod_price'); 
$prod_image = $row_pro('prod_image'); 

以括號

$prod_id = $row_pro['prod_id']; 
$prod_name = $row_pro['prod_name']; 
$prod_price = $row_pro['prod_price']; 
$prod_image = $row_pro['prod_image']; 

爲數組標識符必須在方括號
