Seřazení výpisu z DB

Dobrý den, potřebuji poradit se seřazením výpisu z db. Nevím si vůbec rady. Zde je script:

<?php
include 'config.php';
session_start();

if (isset($_SESSION['player']) && !empty($_SESSION['player'])) {
$player = mysql_real_escape_string($_SESSION['player']);
$playerinfo = "SELECT * FROM uzivatele WHERE jmeno = '$player'";
$playerinfo2 = mysql_query($playerinfo) or die("Nelze!");
$playerinfo3 = mysql_fetch_array($playerinfo2);
  echo "
<center>
<a href='index.php'><div id='buttonf'></div></a>
<a href='pruzkum.php'><div id='buttonn'></div></a>
<a href='arena.php'><div id='buttoni'></div></a>
<a href='prace.php'><div id='buttono'></div></a>
<a href='obchodzbrane.php'><div id='buttong'></div></a>
<a href='obchodvyzbroj.php'><div id='buttonh'></div></a>

<a href='premium.php'><div id='buttonk'></div></a>

<a href='odhlaseni.php'><div id='buttond'></div></a>
<a href='nastaveni.php'><div id='buttone'></div></a>

</center>
";
} else {
echo "
<center>
<a href='index.php'><div id='buttons'></div></a>
<a href='registrace.php'><div id='buttona'></div></a>
<a href='prihlaseni.php'><div id='buttonb'></div></a>
<a href='###'><div id='buttonc'></div></a></center>
";
};
?>

<?php
include 'config.php';

if (isset($_SESSION['player']) && !empty($_SESSION['player'])) {
$player = mysql_real_escape_string($_SESSION['player']);
$playerinfo = "SELECT * FROM uzivatele WHERE jmeno = '$player'";
$playerinfo2 = mysql_query($playerinfo) or die("Nelze!");
$playerinfo3 = mysql_fetch_array($playerinfo2);
$hraci = mysql_query("select * from uzivatele"); 
while ($hraciinfo = mysql_fetch_array($hraci));
   echo "
