php实现refresh刷新页面批量导入数据的方法_PHP
本文实例讲述了php实现refresh刷新页面批量导入数据的方法。分享给大家供大家参考。具体分析如下:
这个功能是参考dedecms生成html页面的原理,只是dedecms使用的是js跳转而我使用的是refresh进行跳转,效果是一样的,下面我们一起来看一个php实现批量导入数据的方法.
因为我有1000W数据一次导入数据库肯定是不可行了,所以我就导致了每一次导入50条或更多数据,然后下次再刷新一次这样就可以解决这个问题了,代码如下:
代码如下:
set_time_limit(0);
//连接数据库
$s = isset( $_GET['s'] )?$_GET['s']:0;
$e = isset( $_GET['e'])?$_GET['e']:50;
$count =85000;
if( $s
{
$sql = "select * from bac_info where isget =0 order by id desc limit $s,$e ";
$query = mysql_query( $sql );
while( $rs = mysql_fetch_array( $query ) )
{
$id = $rs['id'];
$sms = $rs['sms'];
$typeid = $rs['typeid'];
$isget = $rs['isget'];
$sql = "insert into bac_info_bak (id,sms,typeid,isget) values('$id','$sms','$typeid','$isget')";
mysql_query( $sql ) ;
echo $sql;
//exit;
$sqlu = "update bac_info set isget=1 where id =".$rs['id'];
mysql_query( $sqlu );
}
echo '正在处理数据,当前为'.$s.'条......';
}
else
{
echo '完成所有数据处理 再随机排序一次';
}
?>
希望本文所述对大家的php程序设计有所帮助。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
