下面是代码，现在很好.

Here below the code,its fine now.

$fft1=888;
$fft2=777;
$fft3="";
$fft4=999;

$fft5=100;
$ctnqty=10;
$friendslist = "$fft1,$fft2,$fft3,$fft4";
$id = $fft5;
$friendarray = explode(",", $friendslist);
  $frienduserarray = array();

for ($n = 0; $n < count($friendarray); $n++) {
  $friendidpush = "('".$id."','".$friendarray[$n]."','".$ctnqty."'),";
  array_push($frienduserarray, $friendidpush);
 }
 $query = "INSERT INTO freddyhipment (style, orderno,ctnqty) VALUES ";
 $friendarray = explode(",", $friendslist);

 foreach ($friendarray as $order) {
$query .= "('" . $id . "','" . $order . "','" . $ctnqty . "'),";
}

$query = substr($query, 0, -1); // remove trailing comma
