我有一个非常奇怪的问题，我从数据库中获取数据，如果有6个或更多条目，那么它有点开始显示错误的信息。由于某种原因，第6行或更多行的数据会将transaction_id显示为0，但它实际上在数据库中。在执行echo $key之后，它甚至会在数组中显示它。
//修改
解决了，还有一个问题
好像我能够使用===解决问题，但现在的问题是如何使用同样的东西才是数据库查询？因为我有一行所有transactions transaction_id = 0，但它以某种方式获得第6次交易。
这是我的代码：
<? foreach($transactions as $key): ?>
<tr>
<th><?=$key['id']?></th>
<th><?=$key['type']?></th>
<th><?=$key['amount']?></th>
<th><?php if($key['transaction_id'] == 0){echo 'Transaction not completed'; } else { echo $key['transaction_id'];}?></th>
<th><?=$key['user']?></th>
<th><?=date('Y-m-d H:i:s', $key['time']);?></th>
</tr>
<? endforeach; ?>
来自$transactions

试试这个
Object.keys如果这不起作用，请print_r（）显示您的数组内容
获取id = 0的查询：
$key->id
$key->type
....
你的$ transactions print_r（）显示重复，如果它正确运行，请尝试检查事务查询
