updated again.

   $battle_id = md5(uniqid(rand(), true));     echo $battle_id;     // $battle_id 9a8ab59df7079208843086e9b49a7862      // initialise battle log     if(!isset($_session['battle_log']) || !is_array($_session['battle_log']))     {         $_session['battle_log'] = array();     }     // check if battle hasn't been played    if(!in_array($battle_id, $_session['battle_log']))    {        // add played battle log         // ... battle code goes here        if(isset($_post['submit']))     {       $player=$_session['username'];      $playerstats1="select * users username='$player'";      $playerstats2=mysql_query($playerstats1) or die ("could not find player");      $playerstats3=mysql_fetch_array($playerstats2);       $pokemonstat1="select * user_pokemon belongsto='$player' , slot='1'";      $pokemonstat2=mysql_query($pokemonstat1) or die ("could not find pokemon");      while($row = mysql_fetch_array($pokemonstat2)){           $yourmonster="select * pokemon name='".$row['pokemon']."'";      $yourmonster2=mysql_query($yourmonster) or die ("cannot select battle pokemon");      $yourmonster3=mysql_fetch_array($yourmonster2);        $monstername=$_session['pokemon'];      $monstername=strip_tags($monstername);      $selmonster="select * pokemon name='$monstername'";      $selmonster2=mysql_query($selmonster) or die ("cannot select battle pokemon");      $selmonster3=mysql_fetch_array($selmonster2);             $totalskill=$yourmonster3[att] * $row['level'] + $selmonster3[att] * 5;            $randomnumber=rand(1,$totalskill);            if($randomnumber<=$yourmonster3[att] * $row['level'])            {              echo "<center>";                echo "you have won!";              echo "</center>";             } else {                echo "<center>";                echo "you have lost!";                echo "</center>";            }          }     }           $_session['battle_log'][] = $battle_id;    }else {        echo "don't try cheat...";    }

simply set value in session indicating battle has been played user. can check against value see if user has played battle already.

the value save in session unique, battle id. if don't have can create unique battle reference making signature of unique values in battle. so:-

    $battle_id = md5($player.$row['pokemon'].$monstername);     // $battle_id 9a8ab59df7079208843086e9b49a7862

at start of script initialise log of battles played:-

    // initialise battle log     if(!isset($_session['battle_log']) || !is_array($_session['battle_log']))     {         $_session['battle_log'] = array();     }

then before start of battle check if hasn't been played

   // check if battle hasn't been played    if(!in_array($battle_id, $_session['battle_log']))    {        // ... battle code goes here         // add played battle log        $_session['battle_log'][] = $battle_id;    }

so along these lines should work:-

// initialise battle log if(!isset($_session['battle_log']) || !is_array($_session['battle_log'])) {     $_session['battle_log'] = array(); }  if(isset($_post['submit'])) {     $player=$_session['username'];     $playerstats1="select * users username='$player'";     $playerstats2=mysql_query($playerstats1) or die ("could not find player");     $playerstats3=mysql_fetch_array($playerstats2);      $pokemonstat1="select * user_pokemon belongsto='$player' , slot='1'";     $pokemonstat2=mysql_query($pokemonstat1) or die ("could not find pokemon");      while($row = mysql_fetch_array($pokemonstat2))     {         $yourmonster="select * pokemon name='".$row['pokemon']."'";         $yourmonster2=mysql_query($yourmonster) or die ("cannot select battle pokemon");         $yourmonster3=mysql_fetch_array($yourmonster2);          $monstername=$_session['pokemon'];         $monstername=strip_tags($monstername);         $selmonster="select * pokemon name='$monstername'";         $selmonster2=mysql_query($selmonster) or die ("cannot select battle pokemon");         $selmonster3=mysql_fetch_array($selmonster2);          // generate battle id based on unique battle details         $battle_id = md5($player.$row['pokemon'].$monstername);          $totalskill=$yourmonster3[att] * $row['level'] + $selmonster3[att] * 5;         $randomnumber=rand(1,$totalskill);         if($randomnumber<=$yourmonster3[att] * $row['level'])         {             echo "<center>you have won!</center>";         } else {             echo "<center>you have lost!</center>";         }          // check if battle hasn't been played         if(!in_array($battle_id, $_session['battle_log']))         {             // code below run once per battle             // ...              // add played battle log             $_session['battle_log'][] = $battle_id;         }     } }

note: bare in mind session temporary once session destroyed history of battles played lost persist data. create battle table this.
