if(isset($user)){
//if($gconf[0]['open']!=1){

$action=htmlspecialchars(trim($_GET['action']));


switch ($action){

default:
echo "<div class='foot'>";
echo '1 pestisor = 20 de puncte<br/>';
echo '</div>';

$baks=$num*20;
mysql_query("UPDATE `user` SET `balls`=`balls`+'$baks',`extra_ball`=`extra_ball`-'$num' WHERE `id`='".$user['id']."'");

echo 'Ai vandut cu succes pestisorul!';
break;


}

i reveceive the error:
Notice: Undefined index: action in /home/wapcomun/public_html/bere/vinde_pesti.php on line 23 on

$action=htmlspecialchars(trim($_GET['action'])); 

in this line. I don't know how to define $action.

yes is very good :D but need one more update. If i put wink for example like spam word , and i write .wink. ( to show smiley ) appear .wi*k. If you can fix that is a perfect code.

you could also try it like this:

$str = preg_replace(trim('/^\b'.$spam['text'].'\b$/i'), trim($spam['word']), $str); 

adding the ^ modifier at start and $ modifier at end could possibly help further
since it asks to match from the beginning and end exactly. which should then match
wink Wink WiNk etc but not .wink.
