PHP关联数组未打印第一个和第五个键

我有如下所示的PHP关联数组，mysql查询和文件名作为键和值：

$extract_queries = array( 
    "SELECT  rec.time_stamp, rec.day_chan1, rec.day_chan2, rec.day_chan3 FROM ( SELECT ".$this->table_name.".*, DATE(time_stamp) AS mydate, TIME(time_stamp) AS mytime FROM ".$this->table_name."

WHERE TIME(time_stamp) >= '07:00:00' AND TIME(time_stamp) <= '07:59:59' GROUP BY DATE(time_stamp) ) as max_times ON max_times.mydate = rec.mydate and max_times.mytime = rec.mytime ORDER BY rec.mydate" => $current_user."-WinterNightTime1",

);

我的问题是当我打印\r$extract\u查询时； 数组中缺少第1个和第5个键及其值，即使在foreach循环中，它们也会被转义

---

如何获取这些值？

主键在第1个和第5个位置重复，日期/时间相同。将SQL查询切换为值，$current_user.-xxxTime1部分切换为键

+ 1，我也会考虑更好地组织我的代码来避免这些琐碎的错误。
