php - Warning: mysql_connect(): Access denied for user 'root'@'localhost' (using password: YES) -

warning: mysql_connect(): access denied user 'root'@'localhost' (using password: yes) in c:\xampp\htdocs\login\sessionhandler.php on line 35

so what's on line 35.

//to make connection database $conn = mysql_connect("localhost", "root", "password") or die(mysql_error()); 

i don't know whether problem or code i'm writing. have searched every possible answer not looking for.

this code (if problem not on line 35)

//validation error flag $errflag = false;  //input validation if($_post['uname'] == '') {     $errmsg_arr[]='login id missing';     $errflag = true; } if($_post['pword'] == '') {     $errmsg_arr[] = 'password missing';     $errflag = true; }   //if there input validations, redirect login form if($errflag) {     $_session['errmsg_arr'] = $errmsg_arr;     session_write_close();     header("location: login.php");     exit(); }  //to make connection database $conn = mysql_connect("localhost", "root", "password") or die(mysql_error());   //to select targeted database mysql_select_db("ngchoonching", $conn) or die(mysql_error());  //to create query executed in sql $username = $_post['uname']; $password = $_post['pword']; $query = "select * profile username = '$username' , password = '$password'";  //to run sql query in database $result= mysql_query($query, $conn) or die(mysql_error());  //check whether query successful or not if(isset($result)) {     if(mysql_num_rows($result) == 1)     {         //login successful         session_regenerate_id();         $member = mysql_fetch_assoc($result);         $_session['sess_member_id'] = $member['id'];         $_session['sess_first_name'] = $member['firstname'];         $_session['sess_last_name'] = $member['lastname'];         $_session['status'] = true;         session_write_close();         header("location: login-successful.php");         exit();     }     else     {         //login failed         header("location: login-failed.html");         exit();     } } else {     die("query failed"); }  ?> 

i use localhost,phpmyadmin,xampp , don't understand why access denied.

try $conn = mysql_connect("localhost", "root") or $conn = mysql_connect("localhost", "root", "")
