        $grand_total=0;
        while($cart_row=mysqli_fetch_array($cart_item_run)){
            $pro_id = $cart_row['product_id'];
            $pro_qty = $cart_row['qty'];

                       $product_query="SELECT * FROM products WHERE product_id = '$pro_id'";
            $product_run = mysqli_query($conn, $product_query);

只需将输出保存在php var中，并在完成后回显它。如果您只想在某些DOM中将其输出为html，则无需执行此操作（如上所述）。 `

$cart_item_query="SELECT * FROM cart";
$cart_item_run = mysqli_query($conn,$cart_item_query);
if (mysqli_num_rows($cart_item_run)>0){
    $grand_total=0;
    while($cart_row=mysqli_fetch_array($cart_item_run)){
        $pro_id = $cart_row['product_id'];
        $pro_qty = $cart_row['qty'];

                   $product_query="SELECT * FROM products WHERE product_id = '$pro_id'";
        $product_run = mysqli_query($conn, $product_query);
        $product_row = mysqli_fetch_array($product_run);
        $pro_name = $product_row['product_name'];
        $pro_image = $product_row['product_image'];
        $pro_sell_price = $product_row['sell_price'];
        $total = $pro_sell_price*$pro_qty;
        $grand_total =$grand_total+ $total;




        $return_value = "<div class=\"row\">

            <div class=\"col-md-3 col-xs-3\"><img src=\"img/".$pro_image."\" alt=\"\" width=\"50px\"></div>
            <div class=\"col-md-3 col-xs-3\"><p>".$pro_name."</p><a href=\"\"><p><i class=\"fa fa-trash\" aria-hidden=\"true\"></i> Remove</p></a></div>
            <div class=\"col-md-2 col-xs-2\">
                <select class=\"change_qty\" size=\"1\" style=\"width:50px;\">";

                        for ($i = 1; $i <= 9; $i++) {
                            $selected = $pro_qty == $i? 'selected' : '';
                            $return_value .= "<option class=\"qty\" data-pro=\"".$pro_id."\" value=\"".$i."\" ".$selected.">".$i."</option>";
                        }
                    ?>
                $return_value .= "</select>
            </div>

            <div class=\"col-md-2 col-xs-2\"><input data-pro=\"".$pro_id."\" id=\"price-".$pro_id."\" type=\"text\" value=\"".$pro_sell_price."\" disabled class=\"form-control dis-input price\"></div>
            <div class=\"col-md-2 col-xs-2\"><input id=\"total-".$pro_id."\" data-pro=\"".$pro_id."\" type=\"text\" value=\"".$total."\" disabled class=\"form-control dis-input total\"></div>

        </div>

        <hr>";



    }
}
echo $return_value;

} ？＆GT;`

我怎么能在一个回声中包装PHP代码
