}
}
// 检查是否发生错误
function isError()

}
function &query($sql)
{

return new mysqlResult($this, $queryResource);
}
}
}
// 取得SQL查询结果
class mysqlResult
{
var $mysql;
var $query;
function mysqlResult(&$mysql, $query)
{
$this->mysql = &$mysql;
$this->query = $query;
}
function fetch()
{
if ($row = mysql_fetch_array($this->query, mysql_ASSOC))
{
return $row;
}
else if ($this->size() > 0)
{
mysql_data_seek($this->query, 0);
return false;
}
else
{
return false;
}
}
function isError()
{
return $this->mysql->isError();
}
function size()
{
return mysql_num_rows($this->query);
}
}
在红色的那一行会发生
Notice: Only variable references should be returned by reference in
sql.php ...
可是我是照着书上输入的啊Orz
书又没有附光碟(去师大图书馆借的...)
不晓得要怎麽改才正确
乱改又会出更多的错误 囧
所以向各位求救..
希望有大大指点迷津，谢谢。
