    Thank you for your suggestion!

    Thank you for your input and suggestions. There is still some cosmetic work, but the program is now functional. I would like your feedback. I know there are probably better ways to accomplish what I was doing with this program. I have only been working with PHP for about three weeks. Also, since I was using an outdated book, would someone please suggest a good book to learn PHP? <!DOCTYPE html> <!-- Paul Peterson Rock paper Scissors Lizard Spock Survey of Perl Python and PHP Fall 2014 --><?php //initialize stats array $stats = array(); $stats['Win'] = 0; $stats['Lose'] = 0; $stats['Draw'] = 0; $stats['games'] = 0; if(isset($_POST['stats'])) { if(isset($_POST['stats']['Win'])) $stats['Win'] = $_POST['stats']['Win']; if(isset($_POST['stats']['Lose'])) $stats['Lose'] = $_POST['stats']['Lose']; if(isset($_POST['stats']['Draw'])) $stats['Draw'] = $_POST['stats']['Draw']; if(isset($_POST['stats']['games'])) $stats['games'] = $_POST['stats']['games']; } ?> <html> <head> <meta charset="UTF-8"> <title></title> </head> <body> <?php // if human has a value get computer play, compare results and echo results if(isset($_POST['human'])){ $human = $_POST['human']; $computer = computer_play(); $win = $lose = $draw = 0; if(isset($_POST['human'])){ if ($human == $computer){ $draw = 1; $outcome = 'Draw'; }else{ switch($human){ case 'Rock': switch ($computer){ case 'Paper': $outcome = "Lose";$action = "Covers";break; case 'Scissors': $outcome = "Win";$action = "Crushes";break; case 'Lizard': $outcome = "Win";$action = "Crushes";break; case 'Spock': $outcome = "Lose";$action = "Vaporizes";break; } break; case 'Paper': switch ($computer){ case 'Rock': $outcome = "Win";$action = "Covers";break; case 'Lizard': $outcome = "Lose";$action = "Eats";break; case 'Scissors': $outcome = "Lose";$action = "Cuts";break; case 'Spock': $outcome = "Win";$action = "Disproves";break; } break; case 'Scissors': switch ($computer){ case 'Rock': $outcome = "Lose";$action = "Crushes";break; case 'Paper': $outcome = "Win";$action = "Cuts";break; case 'Lizard': $outcome = "Win";$action = "Decapitates";break; case 'Spock': $outcome = "Lose";$action = "Smashes";break; } break; case 'Lizard': switch ($computer){ case 'Rock': $outcome = "Lose";$action = "Crushes";break; case 'Paper': $outcome = "Win";$action = "Eats";break; case 'Scissors': $outcome = "Lose";$action = "Decapitates";break; case 'Spock': $outcome = "Win";$action = "Poisons";break; } break; case 'Spock': switch ($computer){ case 'Rock': $outcome = "Win";$action = "Vaporizes";break; case 'Paper': $outcome = "Lose";$action = "Disproves";break; case 'Scissors': $outcome = "Win";$action = "Smashes";break; case 'Lizard': $outcome = "Lose";$action = "Poisons";break; } break; } } } // if there is an outcome, display results if(isset($outcome) ){ if ($outcome =='Win'){ echo "<br />You ".$outcome."!!<br />Your ".$human."

    I wrote the code in pieces and tested as I went along, the parts that are commented out are the problem. When I added those sections (one at a time) is when this stopped working. That is how I know the problem is there.
  4. doghouse308
    Thank you for your help. I have re-thought this and made significant revisions. The program now runs (mostly) but there are still problems. At the moment there are two sections commented out. The first section is intended to display the results of the hand and the second is to track the game stats. With those sections commented out the program will run but displays nothing in the browser when they are included. One other issue I need to resolve is making the for values required. It will not be good if the user can click submit(play) without selecting anything. I found something at w3 schools site, but was not able to make it work. Please share your comments on this. There is still some house keeping and some finishing touches. But I would like to resolve the issues above before starting to wrap things up.

    Thank you!

    Is it possible to have a static variable in php? I want the value of a variable to remain unchanged the next time a function is called.
  7. doghouse308
    If I try to run this from MAMP, nothing happens. If I try to run it from an IDE (netbeans) it opens window after window after window until I force the browser to close. This is supposed to be a variant of the game rock, paper, scissors - rock, paper, scissors, lizars, spock After reading the responses, I believe the login script will be included in the program for simplicity. This will never be used on a remote server and I don't see the need for the additional complexity. The existing login file is supposed to generate a form to collect the server, username and password information and establish the connection. If the rpsls and choices table are not present, they will be created (a better method of accomplishing this was presented in a previous response and will be incorporated shortly). The last function in the login file is intended to prevent unintended and potentionally damaging information to be sent using the form. After further reflection, I may simply eliminate that too and simply use the information needed to establish the connection with the database in plain english. Going in order through the rest of the script: The game begins with a call to the ready_to_play function that creates a form with radio buttons to begin the game. If 'Yes' is checked the gameResults table is createed and the game begins by calling the rock_paper_scissors_lizard_spock function once the user clicks on the button. If 'No' is selected the close_rpsls function is called, closing the connection and ending the game. The rock_paper_scissors_lizard_spock function calls the human_play function that creates a table for the human play and returns the value to the rock_paper_scissors_lizard_spock function. Next the computer_play function is called and the value returned to the rock_paper_scissors_lizard_spock function. The computer and human values are passed to the game outcome function that queries the rpsls table for the outcome and action that match the human and computer plays and the results of the game are send to the gameResults table. After each play the user is asked if they want to play again using the play_again function that is very similar to the ready_to_play function. If the user selects 'Yes' the rock_paper_scissors_lizard_spock function is called. If 'No' the close_rpsls function is called The user is asked if they really want to quit. If 'No' the rock_paper_scissors_lizard_spock function is called. If 'Yes' the game_statistic function is called (not currently in the included code. It looks like I forgot that function call). The game_statistics function creates a table to display the number of games, wins, losses and draws, DROPS the gameResults table and closes the connection. I think I also need something there to exit the game. I hope that helps.

    ginerjm: Yes, this is the first script I wrote in php. And yes, it is my work written using what I learned in an appearantly outdated book. I appreciate your feedback and will work on the issues. Ch0cu3r:As mentioned above, this was written using information from the book selected for a class I am taking. I did not realize that the information was so far out of date. That was a suggestion from a co-worker, who learned php on his own. I found several of the syntax errors after downloading an editor that works with php. Thank you for the assistance. The overkill as you that you justifiably note is due to the way the program was requested. I don't wish to appear insolent, but what I described is what happens when trying to run this program. I have encountered the same issue using Safari and Firefox.

    I stumbled across this site after being slammed hard elsewhere for being a novice and really not knowing what I am doing. What I have read so far is more encouraging. I just wrote my first program in php and it is not working at all right now. All it keeps doing is opening window after window until I force the browser to close. I am using a Mac running Yosemite and using MAMP. Hopefully that is enough background. I know this is an introduction area, so I will also post this in another forum in case this is closed for being off topic.
