How do I get PHP to create a table, if one does not already exist?

I have to do something with:

$news = mysql_query($sql) or die(print mysql_error());

What can I also add something to $sql?

$sql = "if not exists CREATE TABLE `demo_assignment1` ...

$server = "localhost";
$user = "myname";
$pass = "mypass";
$db = "mydb";
$table = "demo_assignment1";

## What do I add here?

$sql = "CREATE TABLE `demo_assignment1` (
`StudentNumber` varchar(8) NOT NULL default '',
`Exercise1` varchar(100) NOT NULL default '',
`Exercise2` varchar(100) NOT NULL default '',
`TimeStamp` timestamp(14) NOT NULL,
PRIMARY KEY (`TimeStamp`)
) TYPE=MyISAM COMMENT='place something here';";

$myconnection = mysql_connect($server,$user,$pass);

mysql_select_db($db,$myconnection);

## What do I do here?
$news = mysql_query($sql) or die(print mysql_error());

#if table exists, I will now

$sql = "INSERT INTO $table (StudentNumber,Exercise1,Exercise2)
values ('$StudentNumber','$Exercise1','$Exercise2')";
mysql_select_db($db,$myconnection);
mysql_query($sql) or die(print mysql_error());
