代碼如下:

<?php

//數據庫連接就不寫在這里面了

$s = isset( $_GET['s'] )?$_GET['s']:0;

$e = isset( $_GET['e'])?$_GET['e']:50;

$count =85000;

if( $s < $count )

{

$sql = "select * from 表前綴_info where isget =0 order by id desc limit $s,$e ";

$query = mysql_query( $sql );

while( $rs = mysql_fetch_array( $query ) )

{

$id = $rs['id'];

$sss = $rs['sss'];

$typeid = $rs['typeid'];

$isget = $rs['isget'];

$sql = "insert into 表前綴_info_bak (id,表前綴,typeid,isget) values('$id','$sss','$typeid','$isget')";

mysql_query( $sql ) ;

echo $sql;

//exit;

$sqlu = "update 表前綴_info set isget=1 where id =".$rs['id'];

mysql_query( $sqlu );

}

echo '<meta http-equiv="refresh" content="0;url=rand.php?s='.($s+50).'&e=50">正在處理數據，當前為'.$s.'條．．．．．．';

}

else

{

echo '完成所有數據處理 <a href=rand.php>再隨機排序一次</a>';
