PHP如何使用表单将这个数据库数据转移到另一个数据去

在下写的转用户的程序,发出来给你参考下吧! 悬赏才5分,真吝啬!

//从xoops中提取数据

$sql = "SELECT `uid`,`uname`,`email`,`pass`,`user_regdate` FROM `{$xoops['prefix']}users` ORDER BY `uid` ASC LIMIT {$start},{$num}";

$rs = $x-oneRow($sql);

if(empty($rs)){

echo 'p/pfont color="blue"全部转换完毕/font';

die();

}
