i comparing roll no database roll no excel . works fine existing data i.e updates existing . not inserting new data. please check code :else if($num_rows>0)

please me.

below code:

if($_files['excelfile']['name']!="") {     $filename=uploadfile($_files['excelfile'],array(".xls",".xlsx"),"excel_file");     $data = new spreadsheet_excel_reader();     $data->read('excel_file/'.$filename);     $ans=mysql_query("select * studentdata");     $num_rows = mysql_num_rows($ans);     for($i=1;$i<=$data->sheets[0]['numrows'];$i++)     {         $rollno=$data->sheets[0]['cells'][$i][1];         $firstname=$data->sheets[0]['cells'][$i][2];         $lastname=$data->sheets[0]['cells'][$i][3];         $mobile=$data->sheets[0]['cells'][$i][4];         $city=$data->sheets[0]['cells'][$i][5];          if($num_rows<=0)         {             echo('inserting : '.$rollno);             $query="insert studentdata(rollno,firstname,lastname,mobileno,city)values('".$rollno."','".$firstname."','".$lastname."','".$mobile."','".$city."')";             mysql_query($query);         }         else if($num_rows>0)         {             while($rows=mysql_fetch_array($ans))             {                 if($rollno!=$rows['rollno'])                 {                     echo('<p style="color:green">inserting : '.$rollno.'</p>');                     $query="insert studentdata(rollno,firstname,lastname,mobileno,city)values('".$rollno."','".$firstname."','".$lastname."','".$mobile."','".$city."')";                     mysql_query($query);                     mysql_error();                     break;                 }                 else                 {                     echo('<p style="color:red">updating roll:'.$rollno.'and dbr:'.$rows['rollno'].'</p>');                     $query="update studentdata set firstname='".$firstname."',lastname='".$lastname."',mobileno='".$mobile."',city='".$city."' rollno='".$rollno."'";                     mysql_query($query);                     break;                 }              }            }     }  }

i tried putting existing roll's in array!

so made array existing rollno 

while($rows=mysql_fetch_array($ans)) {  $existing_rollno[]=$rows['rollno']; }

then used php function:-

if (in_array($rollno, $existing_rollno))

and worked wanted.
