ZF2 清理数据库查询的变量

Question

在 Zend Framework 2 中进行数据库查询时，我应该如何清理用户提交的值？比如下面SQL中的$id

$this->tableGateway->adapter->query(
  "UPDATE comments SET spam_votes = spam_votes + 1 WHERE comment_id = '$id'",
  \Zend\Db\Adapter\Adapter::QUERY_MODE_EXECUTE
);

Answer 1

执行的时候可以传参数..

 $statement = $this->getAdapter()->query("Select * from test WHERE id = ?");
 $result = $statement->execute(array(99));

 $resultSet = new ResultSet;
 $resultSet->initialize($result);

也可以直接传递给查询方法

 $statement = $this->getAdapter()->query(
    "Select * from test WHERE id = ?", 
    array(99)
 );
 $result = $statement->execute();

 $resultSet = new ResultSet;
 $resultSet->initialize($result);

两者都会产生查询“Select * from test WHERE id = '99'”

如果你想使用命名参数：

$statement = $this->getAdapter()->query("Select * from test WHERE id = :id");
$result = $statement->execute(array(
    ':id' => 99
));

$resultSet = new ResultSet;
$resultSet->initialize($result);

如果您想引用您的表/字段名称等：

$tablename = $adapter->platform->quoteIdentifier('tablename');

$statement = $this->getAdapter()->query("Select * from {$tablename} WHERE id = :id");
$result = $statement->execute(array(
    ':id' => 99
));
