删除此行

if (mysqli_num_rows($rs)>0)

尝试此代码

while($row=mysqli_fetch_assoc($rs)){
      $roll_nos = $row['roll_no'] ;
 if($roll_nos == $roll_no){
  echo "<script type='text/javascript'> alert('User Already Registered'); </script>";
}
else
{
    mysqli_query($con,"INSERT into `bnysfinalyear`(`sr_no`,`roll_no`,`o_tmark`,`o_vmark`,`yoga_tmarks`,`yoga_vmarks`,`s_tamrk`,`s_vamrk`,`ir_tmark`,`ir_vmark`,`o_totalmark`,`yoga_totalmark`,`s_totalmark`,`ir_totalmark`,`date`,`sub1`,`sub2`,`sub3`,`sub4`)
    values('$sr_no','$roll_no','$o_tmark','$o_vmark','$yoga_tmark','$yoga_vmark','$s_tmark','$s_vmark','$i_tmark','$i_vmark','$o_totalmark','$yoga_totalmark','$s_totalmark','$i_totalmark','$date','$sub1','$sub2','$sub3','$sub4')")or die(mysqli_error($con));

    $msg='<div class="alert alert-success">
