How to echo database fields in php ?

So, I'm in need of printing my database data to php page !
I have a table users, where I've Name, E-Mail fields. When I'm trying to select this table and echo field values - I'm getting white page with no errors
What this means ?

Could you please post some sample of getting data from db and echo'ing them ?

 

Test Code

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

mysql_select_db("my_db", $con);

$result = mysql_query("SELECT * FROM person");

echo "<table border='1'>
<tr>
<th>Firstname</th>
<th>Lastname</th>
</tr>";

while($row = mysql_fetch_array($result))
  {
  echo "<tr>";
  echo "<td>" . $row['FirstName'] . "</td>";
  echo "<td>" . $row['LastName'] . "</td>";
  echo "</tr>";
  }
echo "</table>";

mysql_close($con);
?>
