}
}else if ($rows_get >1) {

解决方案

这可能是您的问题的解决方案，即使它有点棘手：

if ($dbconnect->connect_error) {
  die("Database connection failed: " . $dbconnect->connect_error);
}
$query=mysqli_query($dbconnect,"SELECT DISTINCT companyname,client_id,feedback,status from review WHERE status=1 ORDER BY RAND() LIMIT 5");
$query3=mysqli_query($dbconnect,"SELECT companyname,client_id,feedback,status from review WHERE status=3");
$rows_get = mysqli_num_rows($query);

$nq=0;

while($row=mysqli_fetch_array($query,MYSQLI_ASSOC))
{
    if ($rows_get == 1 && $nq < 1) {
        echo $row['companyname'];
        echo $row['client_id'];
        echo $row['feedback'];
        echo $row['status'];
        ++$nq;
    } else if ($rows_get == 2 && $nq < 2) {
        echo $row['companyname'];
        echo $row['client_id'];
        echo $row['feedback'];
        echo $row['status'];
        ++$nq;
    } else if ($rows_get == 3 && $nq < 3) {
        echo $row['companyname'];
        echo $row['client_id'];
        echo $row['feedback'];
        echo $row['status'];
        ++$nq;
    } else if ($rows_get == 4 && $nq < 4) {
        echo $row['companyname'];
        echo $row['client_id'];
        echo $row['feedback'];
        echo $row['status'];
        ++$nq;
    } else if ($rows_get == 5 && $nq < 5) {
        echo $row['companyname'];
        echo $row['client_id'];
        echo $row['feedback'];
        echo $row['status'];
        ++$nq;
    } else {
       break;
    }
}

$nq=0;

while($row3=mysqli_fetch_array($query3,MYSQLI_ASSOC))
{
    if ($rows_get == 0 && $nq < 5) {
        echo $row3['companyname'];
        echo $row3['client_id'];
        echo $row3['feedback'];
        echo $row3['status'];
        ++$nq;
    } else if ($rows_get == 1 && $nq < 4) {
        echo $row3['companyname'];
        echo $row3['client_id'];
        echo $row3['feedback'];
        echo $row3['status'];
        ++$nq;
    } else if ($rows_get == 2 && $nq < 3) {
        echo $row3['companyname'];
        echo $row3['client_id'];
        echo $row3['feedback'];
        echo $row3['status'];
        ++$nq;
    } else if ($rows_get == 3 && $nq < 2) {
        echo $row3['companyname'];
        echo $row3['client_id'];
        echo $row3['feedback'];
        echo $row3['status'];
        ++$nq;
    } else if ($rows_get == 4 && $nq < 1) {
        echo $row3['companyname'];
        echo $row3['client_id'];
        echo $row3['feedback'];
        echo $row3['status'];
        ++$nq;
    } else {

    }
