php循环结果

这个for循环没有给我5、8号房间等的预期结果这里可能有什么错误

您使用X作为循环计数器，并且在循环中改变X。对于每个匹配的房间，通过在测试中增加x，您至少跳过一条记录：

 0 => 
    object(stdClass)[8]

  5 =>

      public 'hotel_id' => string '1' (length=1)
      public 'room_no' => string '4' (length=1)
      public 'start_date' => string '2011-12-14' (length=10)
      public 'end_date' => string '2011-12-31' (length=10)
      public 'room_type' => string 'normal' (length=6)
  6 => 
    object(stdClass)[13]
      public 'hotel_id' => string '1' (length=1)
      public 'room_no' => string '2' (length=1)
      public 'start_date' => string '2011-12-14' (length=10)
      public 'end_date' => string '2011-12-31' (length=10)

      public 'hotel_id' => string '1' (length=1)
      public 'room_no' => string '7' (length=1)
      public 'start_date' => string '2011-12-14' (length=10)
      public 'end_date' => string '2011-12-31' (length=10)
      public 'room_type' => string 'normal' (length=6)

所以，如果x美元在（比如）3匹配，你就把它改为4。然后循环再次循环，PHP将x增加到5，您现在跳过了测试#4。

usort（$room_status，function（$a，$b）{
如果（$a->房间号==$b->房间号）{
返回0；
}其他（$a->房间号）{
返回-1；
}否则{
返回1；
}
});
对于（$i=0，$c=count（$room_status）；$iroom_no.。|；
}
