So here's the issue. After the first won/failed game, when trying to play a new game the first input works and shows SESSION attempts 0. On submit it says SESSION attempts 4. The only additive is $_SESSION['attempts'] = $_SESSION['attempts'] + 1; and only once is the SESSION int set.
Here's the code. Self-made. Feel free to use it if you want. A combo guessing game.
if(!$_SESSION){
session_start();
}
echo '<!DOCTYPE html><html lang="en"><head><title>Guess the Combo</title></head><body><h1>Pick The Right Combo</h1>';
if($_POST){
if($_SESSION['attempt'] == 0){
$_SESSION['one'] = rand(0,9);
$_SESSION['two'] = rand(0,9);
$_SESSION['three'] = rand(0,9);
$_SESSION['four'] = rand(0,9);
}elseif($_SESSION['attempt'] > 0 && $_SESSION['attempt'] < 5){
if($_SESSION['attempt'] = 4){
echo 'You have exceed the max amount of attempts. <a href="unlock-combo.php">play again</a>.The correct code was <b>'.$_SESSION['one'].''.$_SESSION['two'].''.$_SESSION['three'].''.$_SESSION['four'].'</b> Attempts <b>'.$_SESSION['attempt'].'';
session_unset();
exit;
}
}elseif($_SESSION['attempt'] > 4){
echo 'You have exceed the max amount of attempts. <a href="unlock-combo.php">play again</a>.The correct code was <b>'.$_SESSION['one'].''.$_SESSION['two'].''.$_SESSION['three'].''.$_SESSION['four'].'</b>';
