I have this code to create a database based off of a random number.

```
<?php
  $con = mysql_connect("localhost","soociali","[censored]");
  $databasename = rand(5, 7);

  if (!$con)
    {
    die('Could not connect: ' . mysql_error());
    }

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

  mysql_close($con);
?>

```

However, I get this error: `Error creating database: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '6' at line 1`
