修复 Warning: Array_merge() [function.array-merge]: Argument #1 Is Not An Array... 错误

如果你的Zen cart网站使用的是php5的服务器空间，或将php升级为php5的话就会出现这个错误，废话不说，解决方法如下：
--------------------------------------------------------
Zen cart Errors After PHP5 Upgrade

After upgrading a Zen cart site to PHP5 the follow errors occurred when using the customer part of the admin section:

Warning: array_merge() [function.array-merge]: Argument #1 is not an array in /catalog/admin/customers.php on line 782

Warning: array_merge() [function.array-merge]: Argument #2 is not an array in /catalog/admin/customers.php on line 784

Warning: reset() [function.reset]: Passed variable is not an array or object in /catalog/admin/includes/classes/object_info.php on line 17

Warning: Variable passed to each() is not an array or object in /catalog/admin/includes/classes/object_info.php on line 18

解决这几个array_merge() 错误, 只需找到并编辑你的admin/customers.php 文件：

找到这两行：

        $customer_info = array_merge($country->fields, $info->fields, $reviews->fields);
        $cInfo_array = array_merge($customers->fields, $customer_info);
修改为：

        $customer_info = array_merge((array)$country->fields, (array)$info->fields, (array)$reviews->fields);
        $cInfo_array = array_merge((array)$customers->fields, (array)$customer_info);

最后的两个错误是因为在编辑资料不充足的客户时出现的，比如某个客户资料没有人名等信息，只要通过phpMyAdmin在数据库里面把这些客户的资料清掉就行了，希望能帮遇到这个问题的童鞋解决问题，哇哈哈。欢迎留言。如果改不好或者需要修改后文件的可以QQ我，邮件发你。
