PHP &&或if else语句无法正常工作

Question

So I have this survey that I am pulling results from and I have to basically make a bunch of if...else if... statements involving which feedback is submitted.

I have set it up to work correctly...except for one problem. I know it's probably something stupid, but for the life of me I can't figure it out.

Anyways here is the code.

if (($QID_A == 23) && ($row_result_2['Feedback'] == "")) {
    echo "";
}
else if (($QID_A == 23) && ($row_result_2['Feedback'] <= 3)) {
    echo $row_custom['Content'];
}
else if (($QID_A == 23) && ($row_result_2['Feedback'] == 4) || ($row_result_2['Feedback'] == 5) || ($row_result_2['Feedback'] == 6)) {
    echo $row_custom['Content2'];
}
else if (($QID_A == 23) && ($row_result_2['Feedback'] >= 7)) {
    echo $row_custom['Content3'];   
}

The problem I am getting is if $row_result_2['Feedback'] is == to 5 or 6. It just repeats the line over and over again, basically failing to evaluate. It works fine for 4, so I am thinking my problem is somewhere in how I set up the || statements?

Any help would be appreciated. Thank you.

While I'm at it would there be a simpler way to write this statement? So i don't have to copy it for each QID_A field 1-50?

UPDATE:: At this point I am at a loss as to why none of the below solutions are working.. I think this might be a deeper issue as the results are still repeating 24 times... Being that QID_A is 23 I think this might be related.. but I can't seem to find a connection... Thanks again for the help though guys I appreciate it.

Just for the hell of it I tried writing the statements out individually.... same result... for example.

if (($QID_A == 22) && ($row_result_2['Feedback'] == "")) {
echo "";
 }
 else if (($QID_A == 22) && ($row_result_2['Feedback'] <= 3)) {
  echo $row_custom['Content'];
  }
  else if (($QID_A == 22) && ($row_result_2['Feedback'] == 4)) {
  echo $row_custom['Content2'];
 }
 else if (($QID_A == 22) && ($row_result_2['Feedback'] == 5)) {
  echo $row_custom['Content2'];
 }
 else if (($QID_A == 22) && ($row_result_2['Feedback'] == 6)) {
  echo $row_custom['Content2'];
 }
 else if (($QID_A == 22) && ($row_result_2['Feedback'] >= 7)) {
  echo $row_custom['Content3']; 
 }

You need an extra pair of brackets to make it obvious what the precedence should be with your operators (and you don't need the brackets round each expression):

else if ($QID_A == 23 && ($row_result_2['Feedback'] == 4 || $row_result_2['Feedback'] == 5 || $row_result_2['Feedback'] == 6)) {

echo $row_custom['Content2']; }

But you might be better off writing this logic use a case so it's clearer, i.e.

if ($QID_A == 23) {
    switch( $row_result_2['Feedback'] ) {
      case '':
        echo '';
        break;
      case 0:
      case 1:
      case 2:
      case 3:
        echo $row_custom['Content'];
        break;
      case 4:
      case 5:
      case 6:
        echo $row_custom['Content2'];
        break;
      default:
        echo $row_custom['Content3']; 
        break;
   }
}
