Hi, I'd want to show you how important sessions are for php...look this simple game in html...
<?php
// starts new session or recover last one...
session_start();
include("funciones.php");
// There is a game in play...
// If I come from initial form, i must start a new game...
// otherwise, I will follow started game...
if(isset($_POST["palabra"]))
{
// I come from initial form
$_SESSION["palabra"]=$_POST["palabra"];
$_SESSION["max_intentos"]=$_POST["max_intentos"];
$_SESSION["partida_en_curso"]=true;
$_SESSION["intentos"]=0;
$_SESSION["letras"]="";
juega();
}else{
if($_SESSION["partida_en_curso"]==true)
{
$duplicado=false;
for($i=0;$i<(strlen($_SESSION["letras"])) ;$i++)
{
if(( $_SESSION["letras"]{$i} )==($_POST["letra"]) ){ $duplicado=true;}
}
if ($duplicado==false) {
$_SESSION["letras"]= $_SESSION["letras"] . $_POST["letra"];
}
$_SESSION["intentos"]= $_SESSION["intentos"] + 1;
$restantes= ($_SESSION["max_intentos"]) - ($_SESSION["intentos"]);
if($_SESSION["intentos"] < ($_SESSION["max_intentos"] + 1 )){
juega();
}else {
$_SESSION["partida_en_curso"]=false;
echo abre_web("AHORCADO");
echo "<p>Lo sentimos, pero se te han acabado los intentos.</p>";
echo cierra_web();
}
}else{
echo abre_web("Bienvenidos al juego del ahorcado");
echo formulario_principal();
echo cierra_web();
