storing wins/losses in session

kitten2781 · April 17, 2008

I want to store wins and losses in a php session, but I can't figure out how to do it.

Any help is appreciated. ???

Here is my code:

<?php 
session_start();
?>
<html>
<head>
<title>RPS</title>
</head>
<body>
<?php 
$player_choice = $_POST['selection'];
$game_choice = array("Rock", "Paper", "Scissors");
$rand_key = array_rand($game_choice, 1);
$computer_choice = $game_choice[$rand_key];
$rock = $_POST["rock_image"];
$paper = $_POST["paper_image"];
$scissors = $_POST["scissors_image"];
?>
<div align="center"><h2>Rock - Paper - Scissors in PHP</h2></div>
<hr>
<form action="RPSv1.php" method="post" enctype="multipart/form-data">
Select one object:<br>
<input type="radio" name="selection" value="Rock"> Rock<br>
<input type="radio" name="selection" value="Paper"> Paper<br>
<input type="radio" name="selection" value="Scissors"> Scissors<br>
        <input type="hidden" name="MAX_FILE_SIZE" value="300000">

<br><input type="submit" value="Play">
<hr>
<p><b>Result: 
<?php 
echo $result; 
?>
</b></p>
<table border="1" summary="">
<tr>
        <td>
        	<?php 
if ($player_choice == "Rock") {
echo "<img src='rock.gif' border='0'>";
}
else if ($player_choice == "Scissors") {
echo "<img src='scissors.gif' border='0'>";
}
else if ($player_choice == "Paper"){
echo "<img src='paper.gif' border='0'>";
}
else {
echo " ";
}
                ?>
        </td>
        <td>
        	<?php 
$losses = 0;
$wins = 0;

if ($player_choice == "Rock" && $computer_choice == "Paper")
echo " Loses to ";
$losses++;
else if ($player_choice == "Paper" && $computer_choice == "Scissors")
echo " Loses to ";
$losses++;
else if ($player_choice == "Scissors" && $computer_choice == "Rock")
echo " Loses to ";
$losses++;
else if ($player_choice == "Paper" && $computer_choice == "Rock")
echo " Beats ";
$wins++;
else if ($player_choice == "Rock" && $computer_choice == "Scissors")
echo " Beats ";
$wins++;
else if ($player_choice == "Scissors" && $computer_choice == "Paper")
echo " Beats ";
$wins++;
                else {
echo "Tie.";
}
?>
        </td>
        <td>
        	<?php 
if ($computer_choice == "Rock") {
echo "<img src='rock.gif' border='0'>";
}
else if ($computer_choice == "Scissors") {
echo "<img src='scissors.gif' border='0'>";
}
else {
echo "<img src='paper.gif' border='0'>";
}
?>
        </td>
</tr>
</table>
<hr>
<?php 
echo $wins, "wins <br>";
echo $losses, "losses <br>";
?>
<hr>
</form>
<?php 
session_destroy();
?>

Here, this uses sessions and the code is much cleaner.

<?php 
  session_start();

  $choices = array('rock', 'paper', 'scissors');
  $result1 = array('Win', 'Loss', 'Tie');
  $result2 = array('beats', 'loses to', 'ties');

  if (in_array($_POST['selection'],array_keys($choices))) {

    $player   = $_POST['selection'];
    $computer = array_rand(array_keys($choices));

    //Determine the results
    if ($player == $computer) {	//Tie
      $result = 2;
      $_SESSION['ties']++;
    }
    else if ($player==($computer+1) || ($player==0 && $computer==2)) {	//Player wins
      $result = 0;
      $_SESSION['wins']++;
    }
    else { //Player loses
      $result = 1;
      $_SESSION['losses']++;
    }
  }
?>

<html>
<head>
<title>RPS</title>
</head>
<body>

<div align="center"><h2>Rock - Paper - Scissors in PHP</h2></div>
<hr>
<form action="<?php echo $_SERVER[php_SELF]; ?>" method="post" enctype="multipart/form-data">
  Select one object:<br>
  <input type="radio" name="selection" value="0"> Rock<br>
  <input type="radio" name="selection" value="1"> Paper<br>
  <input type="radio" name="selection" value="2"> Scissors<br>
  <br><input type="submit" value="Play">
</form>
<hr>

<?php 
if ($result1) { //Display the results
?>

<p><b>Result: <?php echo $result1[$result]; ?></b></p>
<table border="1" summary="">
  <tr>
    <td>
      <?php echo ucfirst($choices[$player]); ?><br>
      <img src="<?php echo $choices[$player]; ?>.gif" border="0">
    </td>
    <td><?php echo $result2[$result]; ?></td>
    <td>
      <?php echo ucfirst($choices[$computer]); ?><br>
      <img src="<?php $choices[$computer]; ?>.gif" border="0">
    </td>
  </tr>
</table>
<hr>
<?php echo (int)$_SESSION['wins']; ?> wins <br>
<?php echo (int)$_SESSION['losses']; ?> losses <br>
<?php echo (int)$_SESSION['ties']; ?> ties <br>
<hr>

<?php
  }
?>
