更改以下行中的括号:

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

括号

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

因为数组标识符必须在方括号中。
