the SQL is
"SELECT count(*) FROM t1";
to count all rows in that table
mysql_connect("localhost", "mysql_user", "mysql_password") or
    die("Could not connect: " . mysql_error());
mysql_select_db("mydb");
$result = mysql_query("SELECT count(*) FROM t1");
$row = mysql_fetch_array($result, MYSQL_NUM);
echo $row[0];  
mysql_free_result($result);

That was what I copied from your code. Not realy famliliar with mysqli usage. This way should now work:
$result = mysqli_query($link, "SELECT count(*) FROM pollnames");
$row = mysqli_fetch_array($result, MYSQLI_NUM);
echo $row[0];
