PHP - Best Way To Code Real-time Web Game?(game Is Based On Php, Mysql, Jquery)
Hello, I am building an online game(users make a character and move on a map and so on...)
All user data is stored in a mySQL database and I want the users to interact in real-time, but there can be a 1-3 second delay between the communication, but not exceed 3 seconds even if 500 players are playing at the same time.
But for the purpose of the question let's say the users can only chat between one another, if I'll have a solution for that then I can use the same method for more parts of the game.
I can't use websockets because my webhost doesn't support it( I don't want to use pusher.com).
I know I can make real-time apps with ajax long polling, but I think that with 500 players playing at the same time it's not the best solution.
So, finally:
How can I make user interaction as close as possible to a real-time game?
(Without too much load on the hosting server)
(I am sorry if some of my terms are not correct - I am just getting back to coding after a long time...)
Edited by Mythion, 17 August 2014 - 02:34 AM. Similar TutorialsI have a little experience in coding php and am wanting to code a browser-based RPG. (One of the click the link games). I know how to code the login, registration, player list, lost password, etc., but I have no idea where to start with coding the attack, throwing in random chance, strength, agility and so forth; stores, items, money, and so on and so on. Can someone help me? Hi folks, If thought i finally managed to make a 2 player game with PHP and Jquery but i my whole computer gets stucked when the first player has gets his 2nd turn. What i basically have are 2 .txt files where both players units are listed. I will read this file into an array. Each unit has a speed key wich value increases when that unit has made an action, i write the new speed to the file and the script runs again. Heres the script that decides which unit goes first. Code: [Select] $time = 0; $found = 0; while ($found != 1) { foreach ($P1recruit as $p1) { if ($found == 1) break; if ($p1['speed']<$time) { $p1['speed'] = $p1['speed'] * ceil ($time / $p1['speed']); } elseif ($p1['speed']==$time) { $p1turn = true; $p2turn = false; $found ++; } } foreach ($P2recruit as $p2) { if ($found == 1) break; if ($p2['speed']<$time) { $p2['speed'] = $p2['speed'] * ceil ($time / $p2['speed']); } elseif ($p2['speed']==$time) { $p1turn = false; $p2turn = true; $found ++; } } $time ++; } Then follows all the HTML to build up the page. The player who has to act gets a form with choices to do with his unit. The other player gets "Opponents turn" in that window. So in the above code you see $p1turn or $p2turn gets true or false. This is for the Jquery script at the end of all the HTML to tell wich player needs to keep polling the unit files until theres a unit for him to act. Heres the script: Code: [Select] if ($p1turn == true) { if ($battle['player2'] == $_SESSION['SESS_MEMBER_ID']) { echo " <script type='text/javascript'> function turnlistener() { $('#main').load('battlegetnextunit.php'); }; $(function() { setInterval('turnlistener()', 5000 ); }); </script> "; } } if ($p2turn == true) { if ($battle['player1'] == $_SESSION['SESS_MEMBER_ID']) { echo " <script type='text/javascript'> function turnlistener() { $('#main').load('battlegetnextunit.php'); }; $(function() { setInterval('turnlistener()', 5000 ); }); </script> "; } } Now for the first player (the one who starts the battle) he can act properly. The next player can act, but he still is longpolling the .txt files as the form resets. If he acts withing the 5 seconds (setInterval('turnlistener()', 5000 )) the other player gets his turn again but my whole computer starts strugling and i'm not able to select anything in the form. Maybe it's like the players get double longpolling the 2nd turn. But i only have the last code once and obviously only 1 of 2 can run as either $p1turn or $p2turn can be true and it can only run for one player. What could this be? Is doing it this way even possible? I'm trying to figure this out for days now, i really hope someone can help me out. Thanks! I'm working on a web based RPG game, and I want the ability to run different "servers" but I'm not sure what the best way to go about it would be.
First idea: Create a table which would be named, "world" when a character is created, they get to choose a world to join, and then use world_id to know what items, mobs, npc, is in that world. Here is just a quick mock-up of the table.
Second idea: Create a whole new database for the game data, creature_game contains the accounts and forum data. While creature_server_x contains the rest of the game. The structure of each database would be exactly the same.
I want the people that runs the different "servers" to be able to do whatever changes they want, even if that would mean to rewrite the story line. I could do it with both the first and second idea. But I want to hear about what people here think is best and why. Ofc, they won't be able to access or change the tables inside the databases, just the data the tables contains.
Hi, i am thinking of creating a text based game mmorpg using php/mysql etc... I know that a lot of these types of games use a tick based system, but i want it to be realtime, the only game i cna find that uses this is Torn, does anyone know how they make it realtime? I know that ticks can be controlled by cronjobs, but how about realtime? The problem is that the game might involve the player building a house, in a tick based system it could be easy to manage by saying the house will take 3 ticks to complete, but i want the house to be like in 10 minutes of 32 minutes, how can i do this. Someone said to check whenever the player next logs in to check if the house has finished and then say it has been built, but seeing as it is an mmorpg it could affect everyones gameplay, not just the person building it, so this will not work. Thanks and sorry if this is a bit confusing. I currently making a relatively simple turn-based strategy game (kind of like a rock, paper, scissors game) in flash and I have no idea as to what I should use as a socket (or like a socket) to relay players' interactions from one client to another. I have researched various APIs like nonoba and SmartFoxServer, etc but they either force their own interface on you or charge an arm and a leg. I've read that java would achieve what I want, but I just don't know enough about java, sockets or networking to make sense of any of it, let alone trying to utilize it. So I am thinking about using php and a mysql database since I am familiar with them, but I'm concerned about performance even though the game would not be very demanding as it is basically just passing values from client to client via php/mysql. Little info on the game: 3-6 players per room. I have no idea as to how many rooms would be necessary, of course that will be determined by its popularity. The timing is what will concern me, as it must be accurate -1 min intervals or less if all of the players make their selections sooner, but they must all be in sync. I only see about 6-10, small (<20 characters/per) variables needing to be passed per player - so if it were 10 variables, in a room with six players, player 1 would send 10 variables and receive 50 back Another option, that I admittedly haven't researched yet, is an xml socket, but I have no idea how to accomplish this and am concern with performance with that as well - probably just because I'm ignorant about it. So what do you guys think? Think php/mysql could handle this? Or do I need to learn another language/API? Any input would be greatly appreciated. Hello. I just inherited a game stats system but it's not working properly. I'm gonna post the entire script:

The problem is that for some nicknames it returns a proper output which should look like this:
But sometimes it just returns lots and lots of data even if the nickname I ask for is unique enough:
Here's how the database looks:
I don't know what's wrong with the script because I'm a PHP beginner. If someone could take a look at it and tell me what's the issue I'd appreciate. Edited September 22, 2020 by jevgienijThis topic has been moved to Editor Help (Dreamweaver, Zend, etc). http://www.phpfreaks.com/forums/index.php?topic=322054.0 I created a "statistics of site" page, stats.php. Currently stats.php updates every visit, that's over 25 queries for every visit, with over 9,000 visits a day, I wish to cut down. What is the best way to make it so all queries are done every hour, therefore requiring less queries to the database? I assume the best way to go at this would be either to run a time() based script every 60 minutes and: - update this to a new field, then stats.php will require 1 query every visit, plus the 1 every hour. or - update a text file and read that each stats.php visit, meaning just the 1 query every hour. Now, I understand the second option will run much less queries overall, but is it the best way to go? Is there a better way to go about doing this? I have a tic tac toe game that I've been working on for a school project. When I attempt to run it a parse error comes up saying "syntax error, unexpected $end" on line 311.

After weeks of doing tweaks, I come to new issues every time I add something, one would think it would be a lot easier to just get the correct time and day :) The latest issue is that when I try to rewrite a date to a better fomat, it disregards the GMT offset. Like this: 4/14/19, 12:00 PM GMT+2 (=$date) becomes ... 14-04-2019 10:00 when using this code:
$bp_date_to_format = date_create_from_format('Y-m-d\TH:i:sP', $date);
echo date_format($bp_date_to_format, 'd-m-Y H:i');
I figured it would just rewrite the format, keeping the exact time. It isn't. We do have all these sorts of localization functions as well, but because there doesn't seem to be one single standard (each 3rd party API connection we have uses its own default datetime format so it seems).
// Remove UTC Text
$UTC_offset = str_replace('UTC', '', $timezone);
// Get Offset in Minutes
if (stripos($UTC_offset, ':') !== false) {
// Calculate seconds from offset
list($hours, $minutes) = explode(':', $offset);
$seconds = $hours * 60 * 60 + $minutes * 60;
} else {
$seconds = $UTC_offset * 60 * 60;
}
// Get User timezone name from seconds
$timezone = timezone_name_from_abbr('', $seconds, 1);
if ($timezone === false) {
$timezone = timezone_name_from_abbr('', $seconds, 0);
}
// Set new TZ
return date_default_timezone_set($timezone);
Isn't there any "one way"solution that can be used? It's confusing to say the least.
Cheers. Hey First let me say I am not asking exactly how to do this. Just the best method of what I want to do. The idea is to have a database of every model of a dirt bike. A user who is logged in to the system can submit data for a dirt bike (I can create forms for this). On the main page of the database I need to be able to have the user select what model bike and year or years to find the information people submitted in a nice list. Do you think this is to big of a project? I'm doing this as a hobby type thing so there really is no time schedule. For making the database: Would an array be best? Are there any examples somewhat close to what I'm talking about? Can someone point me to a layman's tutorial for a simple hangman game? I downloaded one off the internet, but it doesn't do what I want. The one I use doesn't allow capitalized letters or spaces! I can live without the capitlization but MOST of the words will have spaces and therefore, this code will not work. I want to start a brand new code from scratch but I can't seem to figure it out. I am new to coding and have been coding my site using MySQL, and that's fine, but ALL of the coding for hangman is very confusing for me! Code: [Select] $letters = array('a','b','c','d','e','f','g','h','i','j','k','l','m', 'n','o','p','q','r','s','t','u','v','w','x','y','z', ' '); if(empty($_POST)) { $rightcount = '0'; $wrongcount = '0'; $words = explode("\n", file_get_contents('words.list.txt')); $right = array_fill_keys($letters, ' _ '); $wrong = array(); shuffle($words); $word = strtolower($words[0]); $rightstr = serialize($right); $wrongstr = serialize($wrong); $wordletters = str_split($word); $show = ''; foreach($wordletters as $letter) { $show .= $right[$letter]; } } else { $show = $_POST['show']; $word = $_POST['word']; $lettercount = strlen($word); echo $lettercount . "<br>"; $word = htmlspecialchars($word); $word = mysql_real_escape_string($word); $rightcount = $_POST['rightcount']; $wrongcount = $_POST['wrongcount']; $guess = strtolower($_POST['guess']); $guess = ctype_alpha($guess); if($guess == TRUE) { $guess = strtolower($_POST['guess']); } else { echo "<b>Please use only letters.</b><br>"; $guess = ''; } $letterinstance = @substr_count($word, $guess); $right = unserialize($_POST['rightstr']); $wrong = unserialize($_POST['wrongstr']); $wordletters = str_split($word); if(!(empty($guess))) { if(stristr($word, $guess)) { $show = ''; $right[$guess] = $guess; $wordletters = str_split($word); $rightcount = $rightcount + (1*$letterinstance); foreach($wordletters as $letter) { $show .= $right[$letter]; } } else { $show = ''; $wrong[$guess] = $guess; $wrongcount = $wrongcount + 1; if(count($wrong) == 6) { $show = $word; echo "You lost this round of hangman.<br>"; } else { foreach($wordletters as $letter) { $show .= $right[$letter]; } } } } $rightstr = serialize($right); $wrongstr = serialize($wrong); echo "Right: $rightcount<br>Wrong: $wrongcount<br>"; if($rightcount == $lettercount) { echo "You win!<br>"; } } echo "Incorrect Guesses: "; echo implode(', ', $wrong); echo "<br>"; echo $show; echo "<br />"; echo "<form method='post'> <input name='guess'>"; echo "<input type='hidden' name='show' value='$show'> "; echo "<input type='hidden' name='rightcount' value='$rightcount'> "; echo "<input type='hidden' name='wrongcount' value='$wrongcount'> "; echo "<input type='hidden' name='word' value='$word'> "; echo "<input type='hidden' name='rightstr' value='$rightstr'>"; echo "<input type='hidden' name='wrongstr' value='$wrongstr'>"; echo "<input type='submit' value='guess'> "; echo "</form>"; echo "<a href='hangman.php'>Reset</a>"; That is the code I am using now. The connect to the database and rewarding the user when they guess all the letters work fine, but I need for my other details to be in there and I have NO clue how to do that. I've tried a lot of things but everything just screws up. Here's the code I have now that is from scratch, and it's very basic. I really have no freakin' clue where to go from there. Code: [Select] <?php $words = explode(";", file_get_contents('words.list.txt')); shuffle($words); $word = $words[0]; $upletters = array('a','b','c','d','e','f','g','h','i','j','k','l','m', 'n','o','p','q','r','s','t','u','v','w','x','y','z'); $lowletters = array('A','B','C','D','E','F','G','H','I','J','K','L','M', 'N','O','P','Q','R','S','T','U','V','W','X','Y','Z'); echo $word . "<br>"; $word1 = str_replace($upletters, ' _ ', $word); $word1 = str_replace($lowletters, ' _ ', $word1); echo $word1 . "<br><br>"; echo "<form action = '1.php' method = 'POST'>"; echo "<input type = 'text' name = 'guess' size = '10'>"; echo "<input type = 'hidden' name = 'word' value = '$word'>"; echo "<input type = 'hidden' name = 'word1' value = '$word1'>"; echo "<br><input type = 'submit' value = 'Guess!'></form>"; ?> Can someone PLEASE point me in the right direction! Or give me all the functions I need to use to get through this! Thanks in advance. Haven't done much in PHP for a while, and as a refresher and a bit of a challenge to myself I have decided to write up a simple game of sorts. Basically in the game I have townships, every play has their own town. And I want these towns to have events every 3-10 hours, and have these events have results such as births/deaths/fires/flooding/etc. At the moment I'm looking at this kind of setup: A database table with the city information.. city_id, city_owner_id, city_name, etc. I figure I can make another field such as city_nextevent and fill it with a timestamp plus a random number of seconds. then when the user views their city if city_nextevent is older than current time then run the event function and set the next event time. In my head this idea seems to work well, until I realised that if the user doesn't log on for 20+ hours the events will not stack, they will only get the one event when they next view their town when several events should have passed. I realise I could use a cronjob to check all events across all towns, but is there a better way of doing it. I had also though about adding several fields to the database containing say the next five event times, then updating each field after time had passed. Which gives more events if the user has been offline for 20+ hours. So if the play was offline for say a week, their town would pretty much dry up until they returned. Basically, I want their town to run while they're offline. But was trying to avoid using a cronjob. Anyone have any thoughts on how this could be done? hi iam finished from my online strategy game but iwant add map to it players can see cities and their troops on map any 1 can give me code? Hello Everyone, I am using some code for a hangman game. It is written in PHP. I am using code directly from this website http://www.daniweb.com/code/snippet267046.html and am having issues with it. I have the php file on my web server, and I also have a words.txt file on the server as well. However, I am getting errors, and the game also automatically says "you win!" even when entering just one letter. I'm not sure what is going on, as I am using the exact code from the website. Here is where the file is located: http://www.littlehousegardening.com/hangman/hangmanfinal.php Errors I am encountering: Warning: Unknown: Your script possibly relies on a session side-effect which existed until PHP 4.2.3.

Hello everyone and thanks for reading my request for help
I am working on a basic game where 3 - 5 images will be displayed on each page for the user to see (there should be about 5 pages), each of these images will have a value e.g. -1, +1, 0, -10, +12. When the user clicks on an image his/her score will change and the next page with 3 - 5 new images will be shown. When all of the pages have been shown and the user has a score of lets just say 20 or more then more pages will be displayed, if not then a new page will display stating that the game is over.
My question is how do I give each image a value and how do I show a new set of images based on the overall "score" of the player after the first set of pages have been shown?
And is there a way to display the players score on the page?
Thanks and any answers will be appreciated.

Wow, I have no clue what I'm doing.. I'm trying to make a random game and if you roll a 6, you will win 500 rp and I'm trying to insert the 500 rp into the user who is logged in ($_SESSION['username'). But I... just don't know where to begin. Here is my crappy coding that I just.. am stumped on: <p><?php $dice = rand(1,6); if($dice == 1){ echo "You rolled a <br><b>1</b>"; }if($dice == 2){ echo "You rolled a <br><b>2</b>"; }if($dice == 3){ echo "You rolled a <br><b>3</b>"; }if($dice == 4){ echo "You rolled a <br><b>4</b>"; }if($dice == 5){ echo "You rolled a <br><b>5</b>"; }if($dice == 6){ echo "You rolled a <br><b>6</b>"; } $winner = "500"; if($dice == 6); { include("haha.php"); $cxn = mysqli_connect($dbhost,$dbuser,$dbpassword,$dbdatabase); $sql = "INSERT INTO Member (rp) VALUES ('$winner')"; mysqli_query($cxn,$sql); } ?> so i have an idea for a system that basicly shows a swf, how to play, and description all managed by sql. the url would be like: "www.example.com/play.php?id=531" my sql table would be like this: ___________________ id name swfname description howto 1 example ex1.swf destroy your enemies with your gun mouse to aim, click to shoot 2 example2 ex2.swf race your friends with this new game! Arrow keys to move. Space to use powerup. ________________ I need help creating a system that looks at the id provided in the url, then grabs the information in the sql and broadcasts the swf, and posts the title up top and the description and howto below. anyone have any idea how to do this? Hi!
I was assigned to create a simple php game as a part of my grade, but i got stuck. I'm not really a php expert and this isnt really working. I managed to get some of the code/game working, but it's pointless imo. I'm looking for someone who would take 3 mins and fix this code for me. The game is called "Random number guessing game." From the title you can see that the game is not really complicated.
Code:
<html>
<head>
<title></title>
</head>
<body>
<h1> Ugani Random!</h1>
<? php
if(isset($_POST['submit']))
$x = $_POST['x'];
$num = $_POST['num'];
$x = rand(1, 10)
if($num<$x)
{
echo " Your number is higher! "<br />
}
if($num==$x)
{
echo " Correct! Press Reset to try again! "<br />
}
if($num>$x)
{
echo " Your number is lower! "<br />
}
?>
<p>
<form>
<input type="number" name="quantity"> <br />
<button type="submit" value="<? echo $x?>">Submit</button>
<button type="reset" value="<? echo $num?>">Reset</button>
</form>
</p>
</body>
</html>
