<h1>Number Guessing Game.</h1>

<?php

if (isset($_POST['userNumber'])) {
    $userNumber = $_POST['userNumber'];
    if ($winnerNumber > $userNumber) {
        echo '<h1 style="color:yellow"> higher number.</h1>';
    } else if ($winnerNumber < $userNumber) {
        echo '<h1 style="color:green">lower number.</h1>';
    } else {
        echo '<h1 style="color:brown">Sorry you Lose !, The right number is.</h1>';
    }
}

?>

<form method="POST" action="">
    Enter Number: <input name="userNumber" type="text">
    <button type="submit">Try Here</button>
</form>

<h2>How to Play:</h2>

<pre>
* Server will pick a winner number between 1 and 150.
* You guess what number it is.
* If your guess is too high or too low, Server will give you a win.
* See how many turns it takes you to win!
</pre>

</body>
</html>

How this works ?

PHP Code:


 echo '<h1 style="color:brown">Sorry you Lose !, The right number is.</h1>';

What is the right number ? It just say sorry, Sorry you Lose !, The right number is .............and did not print any Number, that too after i find correct number,

PHP Code:



<?php 

session_start(); 
if (isset($_SESSION['luckyNumber'])) { 

    $luckyNumber = $_SESSION['luckyNumber']; 

} else { 

    $luckyNumber = rand(1,100); 

    $_SESSION['luckyNumber'] = $luckyNumber; } 
if (isset($_POST['userNumber'])) { 

    if ($_POST['userNumber'] == $luckyNumber) { 

        $_SESSION['luckyNumber'] = rand(1,100);     } } ?> 
<html> <body> <center><h1>GUESS MY LUCKY NUMBER</h1> 

<?php 

$guessAttempt = (isset($_POST['guessAttempt'])) ? $_POST['guessAttempt'] + 1 : 0;
if (isset($_POST['userNumber'])) { 

    $userNumber = $_POST['userNumber']; 

    if ($luckyNumber > $userNumber) { 

        echo '<p style="color:blue;font-weight:bold">Try again. ' . $userNumber . ' is too small.</p>';     } else if ($luckyNumber < $userNumber) {

<input type="hidden" name="guessAttempt" value="<?php echo $guessAttempt; ?>">

</form> </center>

</body> 

</html>

How to do $guessAttempt using $_SESSION ?

http://php.flashwebhost.com/sibichan...er_session.php

I tried i like below and removed (<input type="hidden" name="guessAttempt" value="<?php echo $guessAttempt; ?>">) from <form> . Its not working.

PHP Code:



if(isset($_SESSION['guessAttempt'])){

$guessAttempt = $_SESSION['guessAttempt'];

}else {

    $guessAttempt = $_POST['guessAttempt'] + 1 ;}

HERE is the full code ($guessAttempt variable stored in $_SESSION).

No of Guess attempt showing as 1. The number is not increasing.

PHP Code:



<?php 

session_start(); 
if(isset($_SESSION['guessAttempt'])){

$guessAttempt = $_SESSION['guessAttempt'];

}else {

    $guessAttempt = $_POST['guessAttempt'] + 1 ;}
if (isset($_SESSION['luckyNumber'])) { 

    $luckyNumber = $_SESSION['luckyNumber']; 

} else { 

    $luckyNumber = rand(1,100); 

    $_SESSION['luckyNumber'] = $luckyNumber; 

} 
if (isset($_POST['userNumber'])) { 

    if ($_POST['userNumber'] == $luckyNumber) { 

        $_SESSION['luckyNumber'] = rand(1,100); 

    } 

} 

?> 

<html> <body> <center>

<h1>GUESS MY LUCKY NUMBER</h1> <?php if (isset($_POST['userNumber'])) { 

    $userNumber = $_POST['userNumber']; 

    if ($luckyNumber > $userNumber) { 

        echo '<p style="color:blue;font-weight:bold">Try again. ' . $userNumber . ' is too small.</p>'; 

    } else if ($luckyNumber < $userNumber) { 

        echo '<p style="color:blue;font-weight:bold">Try again. ' . $userNumber . ' is too high.</p>';
     } else { 

        echo '<p style="color:green;font-weight:bold">Well done! You got it right! .</p>' . $counter ;     } 

    } 

?> 
<p><strong>No of Guess attempt :</strong> <?php echo $guessAttempt; ?></p><form method="POST" action=""> Enter Number: <input name="userNumber" type="text"> <button type="submit">Guess</button> </form> </center>

When you have an error or don't understand any part of the code, ask in the forum, Some one will be able to explain it different way or point out where the bug is. Don't get stuck with some thing, just ask. Everyone get stuck at some point, a good understanding team can help each other and find solution to problem much faster.
