Question

我在cart.php中收到此错误

解析错误：语法错误，意外''（T_ENCAPSED_AND_WHITESPACE），期望标识符（T_STRING）或变量（T_VARIABLE）或数字（T_NUM_STRING）在第74行的cart.php中

第74行

$subtotal = $_SESSION['cart'][$row['id_number']]['quantity']*$row['price'];



<?php

if(isset($_POST['submit']))
{
    foreach($_POST as $items => $item)
    {
        $items = explode("-",$items);
        $items = end($items);
        $items = explode("submit",$items);
        $items = end($items);

        if($_POST['quantity-'.$items]<=0)
        {
            unset($_SESSION['cart'][$items]);
        }

        else
        {
            $_SESSION['cart'][$items]['quantity']=$item;
        }
    }
}   error_reporting(0);

?>

不确定这是否是你的74行但你为什么使用反引号（`）？删除后试一试。

on  if(!empty($query))`
