PHP - Test My Game - Salvage Nation
Hey guys,
I've tried my hardest to create an online game, give it a whirl. i'll unpause when we get to 20 players.
There's a help page to get you started.
Post here with any bugs or comments!

Similar TutorialsHello, 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. write the algorithm to draw a sphere, the function should have parameters 1. diameter (how many line) 2. character (use which character to draw) eg, draw_sphere(10, '8') will produce: 88888 8888888888888 8888888888888888888 888888888888888888888 88888888888888888888888 88888888888888888888888 888888888888888888888 8888888888888888888 8888888888888 88888 the above is a sphere of 10 lines, which is drawn using the character "8" i cant figure out how to do it, thanks in advanved! Hello All happy new year I am trying to make a php page that detects if something is plugged in to the ethernet port. This would be complex if not impossible. I however managed to do something similar the device that will be plugged in has a static address 192.168.1.1. so I created a ping that says if the device is up or down. function ping($host, $port, $timeout) { $fP = fSockOpen($host, $port, $errno, $errstr, $timeout); $status; if ($fP) { echo "Device is ready to accept data";} else { echo "Device Down - Retrying connection"; } } What I would like to do is have a script that is constantly checking is the device is plugged or when it is not (so sort of a loop or auto detect). The idea is to have an image with the device up or down. Regards and a happy new year JG I am trying to select text to display on condition of the current date. I've set a Unix timestamp for the current date: <?php $todays_date = date("Y-m-d"); $today = strtotime($todays_date); ?> Next I test for the first condition. I want the text to appear for 2 weeks then terminate: <?php $exp_date = "2011-05-09"; $expiration_date = strtotime($exp_date); $start_date = strtotime("-14 days", $expiration_date); if ($start_date < $today && $expiration_date > $today) { echo "<h2>Special Event #1</h2>"; } elseif { At this point, I want to set the exp_date for the next event and test again, but I don't know how to do it. The techniques I've tried appear to evaluate as false and display the default text which follows the final "else": } else { echo "<h2>Default Text</h2>"; } ?> Hi
so i've been learning php for 3 mouth now by reading php 6 Bible and watching lynda and so on...
i was looking for a job in few past weeks and i found out i don't have that kind of self confidence to go for it ! you know when they say : PHP Project Manager , it scar's me...

so i began to search for intern job somewhere and i told myself i should bust my ass 24/7 for few mouth and after that i ll be real php guy and it seems like there is no place to reach not php but almost all programming languages
a year ago i was searching for the same thing but in networking section and there was 100's of intern ship jobs but in programming there is none !

Im trying to show if the selected user has had all the required tests they need so they can have a treatment at a hairdressers. For example the client needs to of had a skin test before they can have their hair dyed. Im struggling on showing which tests the user still needs to have
Currently I'm working with 3 tables.
The treatmentTest table which stores all the required tests
treatmentTest
idtreatmentTest
the user table which has the users details
user
iduser
and the usertest table which stores when they had the test and if it has expired (if it has expired is set to 1)
userTest
iduser
idtreatmentTest
expired
so I need this box to pop up with a warning on each test that is still outstanding but I dont want it to show if there are no tests needed. I obviously need to loop through the results of my query but the query its self is confusing me...
<ul class="list-unstyled"> <li>[treatment Name]</li> <li class="text-italic text-muted">Expired [date]</li> <li><a href="#" class="btn btn-success">Update</a></li> </ul>First I tried looping through all the treatments then inside that loop writing the following
<?php do {
//now foreach treatment test get the resulting test from the usertest table
if (isset($row_testReq['idtreatmentTest'])) {
$col_userTest = $row_testReq['idtreatmentTest'];
}
if (isset($_SESSION['cClient'])) {
$colname_userTest = $_SESSION['cClient'];
}
if (isset($expire)) {
$colname_userTestExpire = '1';
}
mysql_select_db($database_dbconnect, $dbconnect);
$query_userTest = sprintf("SELECT * FROM userTest WHERE idtreatmentTest = %s AND iduser = %s AND userTestExpire=%s",
GetSQLValueString($col_userTest, "int"),
GetSQLValueString($colname_userTest, "int"),
GetSQLValueString($colname_userTestExpire, "text"));
$userTest = mysql_query($query_userTest, $dbconnect) or die(mysql_error());
$row_userTest = mysql_fetch_assoc($userTest);
$totalRows_userTest = mysql_num_rows($userTest);
?>
<li class="list-group-item">
<div class="col-sm-2"><i class="fa fa-2x fa-close text-danger"></i></div>
<div class="col-sm-9">
<ul class="list-unstyled">
<?php if($totalRows_userTest>0){?>
<li><?php echo $row_testReq['treatmentTestName'];?></li>
<li class="text-italic text-muted">Expired <?php echo $fn->sqlShowDate($row_userTest['userTestExpire']); ?></li>
<li><a href="client-treat-test.php?i=<?php echo $row_testReq['idtreatmentTest'];?>&t=<?php echo $row_testReq['treatmentTestToken'];?>" class="btn btn-success">Update</a></li>
<?php } ?>
</ul>
</div>
<div class="clearfix"></div>
</li>
<?php } while ($row_testReq = mysql_fetch_assoc($testReq)); ?>
this doesnt work properly at all. It gave me all the treatments that have expired but if a new treatmenttest was added it wouldnt display that there was a test required.
Does anybody know a different way? I also tried getting all the treatments then all the rows in the userTest table then comparing what the differences where but I struggle with arrays comparisons and im not even sure that was the best way to go about it. Am I going to need two queries? One like the loop above and one that looks for expired treatments and one that looks for treatments the user hasn't had or can this be done in one and if so how??

Edited by ShivaGupta, 23 May 2014 - 04:49 PM. Hi there i just need to assign a class to my echoed vairable. Code: [Select] echo $test class="somecssclass"; Im sure im missing some braces here or something but i cant seem to find it out. Heres the error: Parse error: syntax error, unexpected T_CLASS, expecting ',' or ';' Please help Thanks In my app, the users will take a multiplication test with 10 problems... I'm not sure how I would post the grade that the user got to the database. When the user finishes the test and hits score it should post their Name/Date & Time/ and Score to the database. I have the name and date & time working. Just not sure how I would approach the score. This is my application... It is small and simple to run in browser.

I am then trying to update the database based on any changes made in the form and passed through a POST action. The problem I am having is with the block where I declare short variable names for the $_POST variables that will be passed when the user hits the submit button. For each variable declaration I get an error message like this: Quote Encountered error: 8 in mbr_profile_updt_form.php, line 130: Undefined index: email I have tried testing the $_POST variable using the isset function but it apparently is set but empty. What would be a good way to test to see if the user has pressed the submit button before I go into the processing block that is intended to handle those values from the form? Here is where my code is at right now: Code: [Select] if (!isset($_POST)) { throw new Exception('You have not filled the form out completely - please go back' .' and try again.'); } else { //filled in so create short variable names $email=$_POST['email']; $first_name=$_POST['first_name']; $last_name=$_POST['last_name']; |
