Question

我试图从mysql表中提取所有行。我已创建此代码

function getAllRows($tablename){
            $query = $this->mysqli->prepare("SELECT * FROM `".$tablename."`");
            $query->execute();
            $query->bind_result($results);
            while($query->fetch())
            {
                $rows[] = $results;
            }
            return $rows;
        }

但是我发现了这个错误： ( ! ) Warning: mysqli_stmt::bind_result(): Number of bind variables doesn't match number of fields in prepared statement in D:\wamp64\www\easyApi\configuration.php on line 16

感谢您的帮助。

您必须绑定与起诉选择的相同数量的列你可以选择*返回更多列尝试在bind_result中添加正确数量的var

$query = $this->mysqli->prepare("SELECT col1, col2 FROM `".$tablename."`");

...

$stmt->bind_result($col1, $col2);

mysqli选择查询不起作用
