Numbers Game!!!

Good morning my fellow scholars, last night after work I was thinking of some interesting ways of practicing what we've learned so far and walaah!!! it hit me.. eye popping smiley

Why not create a numbers game where you only need a name to play, to play one simply enters their name, they get welcomed into the game and roll the dice by pushing the play button. When the button is pushed it spins some numbers between 1 and 6 (2 virtual dice). basically there are 2 dice, each time you roll them random numbers are picked from each dice and multiplied by each other, if this results in a score greater than 15 (Because I like number 15) you win the game.. grinning smiley

Anyways here's what I coded, I invited everybody to join in and improve the game, its unfortunate that I don't play blackjack, if new the rules imagine what this game would be like? Anyways guys, on the following code I make use of everything we've learned to date (strings, variables, string manipulation, arrays, function, forms e.t.c) eye rolling smiley

Someone perhaps can help with the fronted or if someone knows blackjack, they could give us a rundown of how the game works. eye rolling smiley

I thought of using the include() function to split the login page from the game but never got around to doing it.. eye rolling smiley

OH!! tja one more thing i created a favicon for the site so you will need a

Language: HTML
 <LINK REL="icon" TYPE="images/ico" HREF="/images/diceGame.ico">

This part is optional guys you can even comment it out if you like, but if you need the image I can email you the favicon.. spinning smiley sticking its tongue out

Hi Sipho,

Cool stuff! there is a lot to learn from your code,
I noticed that once you have opened your php tags and then you want to insert a form inside the php tags
it won't gonna work

<?php

$luckyNumbers = array(1,2,3,4,5,6);

if($yourName){

<form name .......>
<input type ......></form>
}

?>

you will need to close the php tag at the beginning of the form
and re-open the php tag at the end of the form.
therefore, the code above will become

<?php

$luckyNumbers = array(1,2,3,4,5,6);

if($yourName){ ?>

<form name .......>
<input type ......></form>
<?php }

?>

Is that correct ?

Am sorry for the late reply. I was waist deep attending a server SOS, troubleshooting for a better part of yestarday and was socialy absent as a result.. sad smiley

Interesting observation and you are infect right. However there are other ways I could've done it i.e observe the following code:

METHOD 1 -> Commenting out HTML tags with the "\" so they dont get confused with PHP code:

Language: PHP
if($yourName){
    echo "<form NAME=\"form1\" Method=\"POST\".......>"; #Here I commented out the double quotes inside my HTML so the PHP parser sees this -> "<form NAME.......>"
    echo "<input TYPE=\"submit\" ......></form>"; #Same here..
}

Ok method 1 requires a lot of typing and attention to detail as your saw, now lets look at the following METHOD 2:

Language: PHP
if($yourName){
echo <<<myHTML  #echo/print will print all of our HTML code contained inside our <<<EOF EOF; magic tags..
             <form NAME="form1" Method="POST".......>  #pure HTML code here
             <input TYPE="submit" ......></form>  #Same here..
        myHTML;
}  #Lets close the condition here..
 
#OR another way would be to do this:
$form1 = <<<myHTML #initiate a variable with a form
    <form NAME="form1" Method="POST".......>
             <input TYPE="submit" ......></form>
myHTML;
 
if($yourName){
echo $form1;
}

The aim here is to make the php parser ignore the HTML code, when the browser gets it, it presents it as HTML. So tja, the story goes... If this () condition is met, then proceed wth what ever is inside the {} parenthesis .. thumbs up

I hope this helps you..

Hi all
Added a few comments to the logic of the code hope this willhelp others understand php formatting

Language: PHP
if(isset($_POST[';enter';])){  #lets check if the enter button was clicked, if so then lets trim the value from $POST and innitiate the variable $yourName 
                   $yourName = trim($_POST[';username';]);
                   if($yourName){
                      $yourName = $yourName; // think we can get rid of this as we already defined the var with the $_POST[';username';]
                      echo "<h1><span style=\"color: white;\">Welcome to the GAME: <span style=\"color:yellow;\">".$yourName."</span></span></h1>";
                   }else{
   echo "<h2><span style=\"color:red;\">Please enter a valid name!!</span></h2>";
   $youName = ""; #If the above code evaluates to false then $yourName is empty, therefore no game will be played
  }

Language: PHP
<?PHP // keep tags lowercase - good practice
