PHP - Chat Server
I am not sure how I should go about doing this. I have a server that has a chat server on it, people register an account and then have access to this chat server from their application. To initially connect to it, they need a game id and game stamp (kind of like a username/password for the game). I don't want chats from one application to display in another users application. When I created this chat server it was for another purpose, and could only support about 64,510 different chats since each chat ran on its own port. For my current purpose it is a little different some applications can have 1 - 10 chats going at once per user using the application. Say their is 100 people using the application and each is using 5 - 10 different chat windows. With 100 users on at the same time all chatting, that can get up to 1,000 different ports being used. I don't want that, because say there are 100 applications also using chat, that is about 100,000 different ports, and I am pretty sure you cant have 100,000 ports. So! I need a way to make a chat server, any ideas on how I could do this with my php?
need more information? please ask! Similar TutorialsI've been trying to figure out how chat apps work all afternoon to do dynamic data in HTML loading. Can someone please tell me where I'm going wrong for the code flow in this script:
<script>
function submitchat{
if (form1.uname.value=='' || form1.msg.value==''){
alert("fill out whole form");
return;
}
var uname=form1.uname.value;
var msg=form1.msg.value;
var xmlhttp= new XMLHttpRequest();
xmlhttp.onreadystatechange = function(){
if (xmlhttp.readyState==4 && xmlhttp.status=200){
document.getElementById('chatlogs').innerHTML=xmlhttp.responseText;
alert("message sent");
}
xmlhttp.open('GET', '?page=3.2&uname='+uname+'&msg='+msg, true);
xmlhttp.send();
}
</script>
<form name="form1">
enter your chat name<input type="text" name="uname">
message: <textarea name="msg"></textarea>
<br>
<div id="chatlogs">Loading Chat Logs...</div>
<a href="#" onclick="">send</a>
</form>
<?php
$uname = $_REQUEST['uname'];
$msg = $_REQUEST['msg'];
if ($msg!='' && $uname!=''){
$chat="
INSERT INTO chat (
`uname` ,
`msg`
)
VALUES (
'$uname',
'$msg'
)";
$result = mysql_query($chat, $con) or die (sql_death($chat));
}
i am new with web socket
and in same time
I try to make server and client communication for soccer manager application, and for this purpose, i need to create closed "chat rooms" or "games" where two users can watch (read game event) and menage (create) game event (make substitution, formation ... or if you want, to send message to server, that they make changes in formation)
this game (room) mast bi secret, and only this two player can use this game for "read" and "write" events in game
for example: Game no: 200001 between user A and user B in 14.05.
when User A, and User B click on game no. 200001 they can read and write game event.
PS: for now, i create basic chat aplication with PHP, jQuery and webSocket and in this app, all user see wath all other user do (public chat) and i want to make secret chat for specific user (already automate subscribed from server) All work with no problem (i work on this example http://www.sanwebe.c...ket-php-socket)
How i can create chat room(s) and subscribe user to specific chat room?
Thanks
Edited by laponac84, 30 November 2014 - 09:09 AM. I have a PHP web system that store in a windows server. In the system, there is a function for user to upload files to another server (Shared server in Unix). When i try to upload a file, it gives warning: Warning: move_uploaded_file(\\unixserver/sharedfolder/upload/test.txt) [function.move-uploaded-file]: failed to open stream: Permission denied in C:\wamp\www\upload\index.php on line 40 For your information, my username has been assigned in xxx's group that has access to read and write on that folder. Besides, i'm able to open,create and delete files on that folder's server manually (samba). The safe mode setting is off. Does anybody has any idea why this thing happen? Hi, I am not a PHP programmer. I took on a new client with a simple PHP site, without any databases. The site is up and running on the web. I would like to get it running on my local machine for further development. I have latest version of WAMP installed, running Apache version 2.2.11 and PHP version 5.3.0 I created a directory in the WAMP "www" project directory and it shows up there like it's supposed to when I browse to "localhost" Problem: The home page of website displays text but no, images, styles, footer, header, nav links, etc. Here is the code for the home page: <? define("NAV","home"); require_once('local/local.php'); ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>TITLE</title> <meta name="keywords" content=""> <meta name="Description" content=""> <? include("common/dochead.php"); ?> </head> <body onLoad="<? include('common/preloads.php'); ?>"> <!-- ============================ main ============================= --> <div id="main-frame"><div id="main" class="noCollapse"> <? include("common/sign.php"); ?> <div id="right-frame"> <? include("common/navigation.php"); ?> <div id="content-frame"> <div id="content"> <h1>Welcome</h1> <p>This is the content area.

I have spent many hours on this. Regards I'm trying to make a simple website where people register to my website. When the user doesn't fill anything inside the boxes they get a message "Please fill all required fields" on the register.php page On my local host require_once works good. It shows up.
But when i upload the files to my sever the require_once does not show up on the register.php It just refreshes and i dont get the message "Please fill all required fields"
This is the code that works in local host but not in a live server <?php require_once 'messages.php'; ?>
Here is my full code
Register page: <html> <?php require_once 'messages.php'; ?> <br><br> <form action="register-clicked.php" method="POST"> Username:<br> <input type="text" name="usernamebox" placeholder="Enter Username Here"> <br><br> Email:<br> <input type="text" name="emailbox" placeholder="Enter email here"> <br><br> Password:<br> <input type="password" name="passwordbox" placeholder="Enter password here"> <br><br> Confirm Password:<br> <input type="password" name="passwordconfirmbox" placeholder="Re-enter password here"> <br><br> <input type="submit" name="submitbox" value="Press to submit"> <br><br> </form> </html>
Register clicked <?php
session_start();
$data = $_POST;
if( empty($data['usernamebox']) ||
empty($data['emailbox']) ||
empty($data['passwordbox']) ||
empty($data['passwordconfirmbox'])) {
$_SESSION['messages'][] = 'Please fill all required fields';

try{
$connection = new PDO($dsn, $dbUser, $dbPassword);
} catch (PDOException $exception){
$_SESSION['messages'][] = 'Connection failed: ' . $exception->getMessage();
header('Location: register.php');
exit;
}
messages.php <?php
session_start();
if (empty($_SESSION['messages'])){
return;
}
$messages = $_SESSION['messages'];
unset($_SESSION['messages']);

Edited Wednesday at 12:49 AM by bee65 Hi folks, I'm curious if I can for example, save a file from my server and it will save to all other servers - obviously if they accepted the connection first. It's for a software I developed and is almost complete and know there will be frequent updates to it. Instead of users downloading upates, I want the update files from my server to somehow synchronize to their server automatically? Anything called this?? Thanks for info. Following a tutorial on udemy, i tried to learn the very basics of mvc structure. I built the same project on my local server and it worked without giving me any error. but when i tried it on live server. its not working as it should. not showing any error. I tried to figure out the problem and found that for every page loading, it stops at the same line in my main.php file. <?php require($view); ?> starting from the above line. it stops. i came here to share my problem but i am unable to upload my files here. if there is a way to upload and share my files, please guide. zip file size of the whole project is 31.6 kb This isn't exactly an application design question, but rather a system design one.
I am about to install an Inventory Control System inside this store I work in.
The store itself also owns a Linode VPS running Centos 6.4 which hosts our website.
This new Inventory System will come built in with a Microsoft SQL Server, and supposedly it is a SQL Anywhere database, but I'm not too sure what that means.
I need to make this database publicly accessible, but only via the Linode VPS. Surely, setting restrictions is easy enough to address that issue. That isn't my question.
My first idea is to put this server into the DMZ, easy. But it doesn't exactly sound safe. So my next idea was to put a middleman server in the DMZ, this way the Linode can send queries to that middleman server and it will send that data to the SQL Server and back. This is very vaguely described I know, but I don't want to get too much into details, but rather, understand how I can create that middleman server, and what could Install onto it that would allow me to securely process queries?
My first thought was to install a webservice, that accepts an XML/JSON request and returns an XML/JSON response.
Then, I realized directly afterwards that I don't have any experience setting up a webservice like that.
What kind of options are there out there? Ultimately, my question is, should I just put the Server in the DMZ or should I create the middleman, and if so, can someone point me in the right direction as to getting a webservice set up? Edited by Zane, 15 July 2014 - 11:28 PM. (This might be the wrong forum; it might be server-side configuration, but alas it is the code that *calls* fwrite, so I'll start here.) I have written a script, and one thing it does is generate a file to disk using fwrite. No big deal. Here's what interests me: On most servers, the file is written successfully when the folder's permissions are 755 with recursive permissions. On some servers, 755 fails. Only 777 works. How could this be? Are permissions=permissions=permissions? Why will 755 work on one machine but not another? I'm just a logic guy; I know very little of server-side configuration and/or why there would be a difference here. Just trying to learn. Hey. I am wanting to move a couple of files from my current server to another. If i am uploading the file this is fine but if it is already on the server then im not sure how to move it. When uploading I can just use ftp_put($conn_id, $destination_file, $myFile, FTP_BINARY); What i need to do is figure out how to get a hold of the file and store it in $myFile then this would work fine. Is this possible? Cheers Hi All... I am facing some problem while coding chat system.....my problem is that whenever i refresh the chat page the last message stored in the url by the current user displays again....its showing messages from the other users also but its keep on repeating the messages of the current user logged in,in the browser.....i am using post for all....do i need to try something else or any new way etc....if anybody have suggestions and solutions for the above mentioned problem then please do help me out...thank you...
