I have tried using the following script to create tables, but always get an error message.
<?php
$con = mysql_connect("localhost","pete","";
if (!$con)
{
die('Could not connect: ' . mysql_error());
}

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

// Create table
mysql_select_db("my_db", $con);
$sql = "CREATE TABLE Persons
(
FirstName varchar(15),
LastName varchar(15),
Age int
)";

// Execute query
mysql_query($sql,$con);

mysql_close($con);
?>


Error is "Error creating database: Access denied for user ''@'localhost' to database 'my_db' "

Any ideas?
