Need Help With This Basic Php by Setag(op): 7:41pm On Jan 22, 2016

Let's say we're gonna be rolling a die:

$die = rand(1, 6);

Whilst the die is being rolled (the value of $die remains the same till user makes the right guess), the user tries to guess the value of the die. Program tells the user if the guess is higher (or lower) than the die value if guess is incorrect, program tells user how many times it took to guess the value of the die right if it took more than one turn to make the right guess.

Immadiately user gets it right, game starts over again(the die is rolled again).

Get the value of $die and set it as a session variable. When the user get the answer, you reset the value

Try this


<!DOCTYPE html>
<html>
<head>
<title>
Die
</title>
</head>
<body>
<?php
	session_start();
	if (isset($_POST['guess'])) {
		//check if session is set for die

		if (isset($_SESSION['die'])) {
			//check user answer
			if ($_POST['answer'] == $_SESSION['die']) {
				echo "<p>Thumbs up!, you guess right.</p>";
				unset($_SESSION['die']);
			}else{
				echo "<p>Incorrect Guess, please try again</p>";
			}
		}else{
			//roll the die again
			$die = rand(1,6);
			if ($_POST['answer'] == $die) {
				echo "<p>Thumbs up!, you guess right.</p>";
			}else{
				$_SESSION['die'] = $die;
				echo "<p>Incorrect Guess, please try again</p>";
			}
		}
	}
?>

<form action="" method="post">

<input type="text" name="answer" id="answer" required />

without even trying it out, I know it won't work!

you base a condition on a button?! I wouldn't do that though.
