php實現mysql資料庫隨機重排例子

程式程式碼




 程式碼如下 複製程式碼 

//資料庫連線就不寫在這裡面了
$s = isset( $_GET['s'] )?$_GET['s']:0;
$e = isset( $_GET['e'])?$_GET['e']:50;
$count =85000;




if( $s < $count )
{
 $sql = "select * from 表字首_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'];
()
  $sql = "insert into 表字首_info_bak (id,表字首,typeid,isget) values('$id','$sss','$typeid','$isget')";
  mysql_query( $sql ) ;
  echo $sql;
  //exit;
  $sqlu = "update 表字首_info set isget=1 where id =".$rs['id'];
  mysql_query( $sqlu );
 }
 echo '正在處理資料，當前為'.$s.'條．．．．．．';
}
else
{
 echo '完成所有資料處理 再隨機排序一次';
}
