2. About file comparison based on database

prepare("select name ,passwd from auth where name=? and passwd=?");
   $stm->bind_param("ss",$user,$passwd);
   $stm->execute();
   $stm->store_result();
   if ( $stm->num_rows == 0 ){
       authenticate_user();
   }else{
       echo "you are sucessful to login !";
   }
}

Corresponding database (httpauth) The plain text verification method can also be used to encrypt and compare the database and PHP original data by yourself

use httpauth;
create table autht(
id int(10)  UNSIGNED not NULL  AUTO_INCREMENT,
name VARCHAR(50) NOT NULL  DEFAULT '' ,
passwd VARCHAR(50)  not NULL DEFAULT '',
harsh VARCHAR(50)  DEFAULT '',
PRIMARY KEY(id,name),
INDEX `asd` (name)
