for ($i=1; $i<=$count; $i++)
{ //$count; will be passed from form A
  $temp = "Q" . $i;
  $Q . $i = $_POST[$temp];
  echo $Q . $i;
}

if your table like this :
QID | QVALUE
the query statement will be

$query = "INSERT INTO table (ID, QVALUE) VALUES ";
for ($i=1; $i<=$count; $i++)
{ //$count; will be passed from form A
  $temp = "Q" . $i;
  $Q . $i = $_POST[$temp];
  $tmp .= "('$temp', '$Q . $i'), "
  //echo $Q . $i;
}

$query = $query . $tmp;
$query = substr($query, strlen($query)-2);

my table is in the format of

field -> Q1  Q2 Q3 Q4 ......

now if I use your code, the display result is:
INSERT INTO Form (Q1, Q2) VALUES('Q1', '.4'),

my expected statement is

INSERT INTO Form (Q1, Q2, Q3, Q4 ...) VALUES('1','2','2',....),

$query = "INSERT INTO table";
for ($i=1; $i<=$count; $i++)
{ //$count; will be passed from form A
  $temp = "Q" . $i;
  $value = $_POST[$temp];
  $tmp .= "'$value' , ";
  $tmp1 .= $temp. ', ';
  //echo $Q . $i;
}
$tmp1 = substr($tmp1 , strlen($tmp1) - 2); // Cut ', ' at the end.
$tmp = substr($tmp , strlen($tmp) - 2); // Cut ', ' at the end.

$query = "(" . $tmp1 . ") VALUES (" . $tmp . ")";

i change into this

$tmp1 = substr($tmp1 , 0, -2); // Cut ', ' at the end.
$tmp = substr($tmp , 0,-2); // Cut ', ' at the end.

and it works fine now
