我必须说我对PHP完全无能为力，我知道足以将我的网站调整到可接受的程度。我在使用phpauction GPL时遇到了一些麻烦，每当我点击其中一个类别时，我都会这样：
致命错误：第175行/home/retrorea/public_html/tradepost/browse.php中不支持的操作数类型
这是第175行的内容......
$left_limit = ($page-1)*$lines;
这是代码的其余部分。

非常感谢任何帮助。谢谢！
答案 0 :(得分：1)
要强制该值为整数，请使用intval。
答案 1 :(得分：0)
尝试在这些行的正上方添加此代码：
echo "<pre>";
var_dump($lines, $page);exit;
可能发生的事情是你得到一个布尔值或null或一些其他数据类型乘以它无法乘以的东西。该代码将告诉您这两个变量的数据类型。
你可能最终将这一行包含在这样的内容中：
if(is_numeric($lines) && is_numeric($page)){---your code----}else{$left_limit = --whatever your want as default value--}
答案 2 :(得分：-1)
试试这个：
$left_limit = ((int)$page-1)*(int)$lines;
