i want to loop through the values of array which contain $i variable in it,

my code for array looks like this,

foreach($fields_names as $k => $v) {
      $handle_data[] ='$rowdata[$i][$fields_names[\''.$v.'\']]';
}

for($i=0;$i<$number_rows_excel;$i++){

$sql.= "('".implode("','", array_values($handle_data))."'),". "<br/>";

        }

when i am echoing $sql, i am getting like this ,

INSERT INTO eximport (`S.No`, `Patent#`, `Title`) VALUES ('$rowdata[$i][$fields_names['S.No']]','$rowdata[$i][$fields_names['Patent#']]','$rowdata[$i][$fields_names['Title']]')

it should have to display like this

INSERT INTO eximport (`S.No`, `Patent#`, `Title`) VALUES ('$rowdata[0][$fields_names['S.No']]','$rowdata[0][$fields_names['Patent#']]','$rowdata[0][$fields_names['Title']]')

please give little advices , how can i use the variable $i in it

thanks
