//mysqli 增强-批量执行sql 语句
//批量执行dql
//使用mysqli的mysqli::multi_query() 一次性添加3个用户
$mysqli =new MySQLi("localhost","root","root","test");

die ("连接失败".$mysqli->connect_error);

//注意分号
$sqls="insert into user1 (name,password,email,age) values('AAA',md5('AAA'),'[email protected]',25);";
$sqls.="insert into user1 (name,password,email,age) values('BBB',md5('BBB'),'[email protected]',25);";
$sqls.="insert into user1 (name,password,email,age) values('CCC',md5('CCC'),'[email protected]',25);";
//批量执行dml 可以混合使用delete insert update 最好不要使用select
