การใช้ array วนอ่านไฟล์ที่มีหลาย field รบกวนช่วยดูให้หน่อยคะว่าเขียนผิดอย่างไร

$objConnect = odbc_connect("mydatabase","","") or die("Error Connect to Database");
$objExec1=odbc_exec($objConnect ,"SELECT * FROM tbl_E");
$num_filed=odbc_num_fields($objExec1);

for($a=1;$a <=$num_filed;$a++){
   $FieldNa[$a]=odbc_field_name($objExec1,$a)."</br>";
  $dataType[$a]= odbc_field_type($objExec1,$a)."</br>"; 
}


while(odbc_fetch_row($objExec))
{
    $LastRec = odbc_result($objExec,"LastTi")  ;
    echo"Last record in database is ".$LastRec."</br>";
    //$FieldNa=odbc_field_name($objExec1);
}

$fileCSV = "xxxx.csv"
            $length = 1000;
            $array = file($fileCSV);
            for($i=0;$i<count($array);$i++)
            {
            if ($length < strlen($array[$i]))
            {
            $length = strlen($array[$i]);
            }
            }
            unset($array);

$handle = fopen($fileCSV, "r");
if(!$handle = fopen($fileCSV, "r"))
{
     print 'could not open file. quitting';
     die;
}
while(($data = fgetcsv($handle, $length, ",")) != FALSE) {
foreach($data as $key=>$value)
{ $data[$key] = "'" . addslashes($value) . "'";
 if(is_numeric($dataType))
 { if($value=""){ $data[$key] = null; }
  else{ $data[$key] = "" . addslashes($value) . ""; } }
   if($dataType=="DATETIME")
   { $data[$key] = "'" . addslashes($value) . "'"; } 
}  
$rows[0] = implode(",",$data);
$sql_rr= "";
$sql_rr .= "INSERT INTO tbl_E($FieldNa ) VALUES(";
$sql_rr .= implode("),(", $rows);
$sql_rr .= ")"; 
}
fclose($handle);
odbc_close($objConnect );
