如何做到多筆資料的同步

#在這裡呼叫資料庫

$query="select * from $userstable where...................

＃進入loop逐一取出資料

$i=0;

while ($i < $num):

...............

$id=mysql_result($result,$i,"id");

..................

............................

＃以適當的type取出必須更新的欄位，構成array ..........

echo "

echo "";

echo "";

$i++;

endwhile;

======================================================

####2.activate.php:資料更新後，透過loop+array完成回存...................

.......

for ($i = 0; $i < count($Cname); $i++) {

$name = $Cname[$i];

$id= $Cid[$i];

$query = "update $userstable set name='$name' where id='$id'";
