$db_host="localhost";

$connect = mysql_connect("localhost","root","ash123");
mysql_select_db("MUSIC");
echo "connection successful";

but when I go to localhost and type localhost/connect.php , I get this error:

Object not found!

I have searched but I have found a solution to this problem, please help!

Answer 1

i am trying to connect to this database using a php file which i have stored in the OML folder which in turn is present in the htdocs folder

So, the URI would be /OML/connect.php instead of just /connect.php , right?

Answer 2

尝试在地址栏中输入以下内容：“ localhost / OML / connect.php”

Answer 3

$connect = mysqli_connect("localhost","root","ash123","MUSIC");

Replace this code in database connection file . Remove the codes you shown .

Answer 4

mysql_connect() is deprecated , and you improperly select the database.

Your code should be:

$db_name="MUSIC";
$db_user="root";
$db_pwd="ash123";
$db_host="localhost";

$link = mysqli_connect($db_host, $db_pwd, $db_name);
if (!$link->connect_error) {
  echo "connection successful";
} else {
  echo $link->connect_error
}

At that point the connection is established, and the DB is selected.

Answer 5

Please try this to connect to your data base

<?php
$connect = mysqli_connect("localhost", "root", "ash123", "MUSIC");
if(mysqli_connect_errno())
{
    echo "Warning ERROR while connection DataBase." .mysqli_connect_errno();
}
?>
