php+mysqli实现批量执行插入、更新及删除数据的方法,phpmysqli
本文实例讲述了php+mysqli实现批量执行插入、更新及删除数据的方法。分享给大家供大家参考。具体如下:
mysqli批量执行插入/更新/删除数据,函数为 multi_query()。
下面的代码只是批量插入数据,事实上,插入数据、更新数据、删除数据等可以混合一起执行。查询时使用该函数,读取数据有点不太一样,具体参考如下代码:
<?php //1、创建数据库连接对象 $mysqli = new MySQLi("localhost","root","123456","liuyan"); if($mysqli->connect_error){ die($mysqli->connect_error); } $mysqli->query("set names 'GBK'"); //2、数据插入语句 $sqls = "insert into news(title,contents,datetime,hit) values('去哪儿网架构调整铺垫上市','据接近去哪儿网的消息人士透露,事业部以运营、收入、利润进行考核;新业务部则是以产品运营、商业模式、总亏损进行考核。','".date('Y-m-d H:i:s')."',30);"; $sqls .= "insert into news(title,contents,datetime,hit) values('告诉金主 视频网站谁是NO.1','搜狐说,自己稳稳超过土豆,是行业老二;腾讯说,自己已经超过了优酷,成为行业第一;土豆不承认腾讯的计算方法,坚称自己仍然是亚军;爱奇艺则摆出数据称在单用户观看时长方面排名第一位。','".date('Y-m-d H:i:s')."',30);"; $sqls .= "insert into news(title,contents,datetime,hit) values('苹果正滋生傲慢情绪','据国外媒体报道,没有经历重大挫折的成功往往会让人滋生傲慢。在过去10年中,苹果取得了巨大的成功,成为了音乐播放器和手机市场上的领导者,但却没未遭遇任何较大的挫折。','".date('Y-m-d H:i:s')."',30);"; //3、执行,注意批量执行函数 $res = $mysqli->multi_query($sqls);//返回的是布尔值 //4、判断是否执行成功 if(!$res){ echo "数据插入失败"; }else{ echo "成功!!!"; } //5、关闭连接 $mysqli->close(); ?>
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,
