我之前已经发布了代码,但是因为我真的不知道发生了什么,所以提出了不同的要求。
我有几个 while 循环从数据库中获取数据以形成最新信息的提要。在你问之前,我会使用 mysqli,但我现在只是使用 mysql,所以我可以对循环进行排序,因为我觉得这样更舒服。
每个 sql 查询可以但不一定有几行数据,因此需要一个 while 循环。我还必须在最后将所有数据组织到一个数组中,以便它们都可以按时间戳排序(时间戳不在 sql 查询中)。
我遇到的问题是将它全部组织到数组中,按照现在的方式,所有右大括号必须在数组之后,以便可以将每一位数据放入其中。由于这个原因,一些变量可能会被多次输出,因为每个 sql 查询中可能有不同数量的行。顺便说一下,括号暂时不是这样排列的。
在下面的代码中,第二批 while 循环中的每一个的括号都紧跟在变量之后。这意味着表中只有一行输出到数组中。
我希望这能解释它。这是我能做的最好的。如何安排 while 循环,以便将来自第二批查询的每个查询的所有数据输出到数组中?
