当我尝试在IF语句中检查是否有多于1个参数时，代码将不再起作用...为什么？

Question

I'm perplex about an IF statement I'm trying to make work. I need to check if the actual hour is in a range of numbers...

Example:

$currentTime=date('H', $dateToCheck);

if($currentTime<18 && $currentTime>7)
{
   do something;
}

The problem is that whenever I try to check the time with only one statement the IF will work but if I use "&&" and add another statement the IF won't work anymore.

(Of course both of the statement are true so the if should be executed)

The code I'm actually working on is the following

    $orarioMess=date('H',$queryDate);
    if($orarioMess<18 && $orarioMess>7)
    {
      $status=12;
      $checkStatus=1;
    }

I expect the IF still to be executed even with 2 statements to check. I have no clue why it isn't working...
