无法在服务器上使用PHP创建MySQL数据库？

Question

I keep getting this error, and I'm not really sure why this isn't working here.

I'm trying to create a database with PHP and it's returning the following error:

Error creating database: Access denied for user 'scriptcooke'@'10.%' to database 'my_db'

I believe I have the correct credentials, but what does @10.% even mean?

NOTE: I'm trying to use the w3schools code example here:

<?php
$con = mysql_connect("localhost","peter","abc123");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

if (mysql_query("CREATE DATABASE my_db",$con))
  {
  echo "Database created";
  }
else
  {
  echo "Error creating database: " . mysql_error();
  }

mysql_close($con);
?>

@10.% is the field for the source host in the user definition.

The problem is: You don't have the permissions to create a new database. The user you are using may only use his own database;
