Question

I make "Guess my number in PHP " and I don't know how to make "tries", because right now I got 10 tries but it count down every time. I guess a number and after 10 tries, I can still guess the number.

I got 3 files. index.php Guess.php The last file is only a view with a form

Index.php file

<?php

// Guess my number

require __DIR__ . "/config.php";
require __DIR__ . "/autoload.php";

// Start a named session
session_name("maub");
session_start();

//Deal with incoming variables
$guess = $_POST["guess"] ?? null;
$doInit = $_POST["doInit"] ?? null;
$doGuess = $_POST["doGuess"] ?? null;
$doCheat = $_POST["doCheat"] ?? null;


// Settings for session.
$number = $_SESSION["number"] ?? null;
$tries = $_SESSION["tries"] ?? null;
$games = null;

// Init the game
if ($doInit || $number === null ) {
    session_destroy();
    session_start();
    $games = new Guess();
    $_SESSION["number"] = $games->number();
    $_SESSION["tries"] = $games->tries();
} elseif ($doGuess) {
    $games = new Guess($number, $tries);
    $result = $games -> makeGuess($guess);
    $_SESSION["tries"] = $games -> tries();
}

// Render the page
require __DIR__ . "/view/guess_my_number.php";

echo "<pre>";
var_dump($_POST);
echo "<br>";
var_dump($_SESSION);

At some point you just need an if statement in your main logic.

if($games->tries() < 1 ){
  echo 'To many guesses';
  // Reset the game.
 }
