php mysqli 使用prepare

 

  1，绑定参数

 

  $mysqli=new mysqli($host,$user,$pass,$db);  
   if(mysqli_connect_errno()){  
    echo '连接出现异常了:'.mysqli_connect_error();  
    exit(0);  }  
      
   $sql = 'insert into user(name,pass,email) values(?,?,?)';  
   $stmt = $mysqli->prepare($sql);  
   $stmt->bind_param('sss',$name,$paassword,$email);  
   $name= '2';  
   $paassword=md5('12345');  
   $email = '[email protected]';     
   $stmt->execute();  
     
   echo '修改了'.$stmt->affected_rows.'行';  
     
   $stmt->close();  
   $mysqli->close();

 

2，绑定结果集

 

$sql = 'select name,pass,email from user';  
  if($stmt = $mysqli->prepare($sql)){  
    $stmt->execute();  
    $stmt->bind_result($name,$pass,$email); //绑定结果  
    echo "

";  
    while($stmt->fetch()){  
        echo "";  
        echo "";  
        echo "";  
        echo "";  
        echo "";  
    }  
    echo "

".$name."

".$pass."

".$email."

";  
    $stmt->close();  
  }  
    
  $mysqli->close();
