Real-time Chat
I wrote a PHP chat system similar to gChat which simply uses constant ajax calls to update the chat. This system is fine for a few users, but with potentially thousands of users, it is much too hard on the server. I've been considering taking the 'Comet' route, but have heard that PHP can't handle Comet very well. What would be the best language/API to perform real-time chat for a large user-base?

Real-time Output?
I'm a relative PHP newbie, so I apologize if this is a simple question. Anyway, here's my problem. I'm using a PHP script to pre-render a bunchload of insert files for an HTML page. Right now there's about 1,600, but that number could get much, much higher when the site goes live. I'll only need to re-render the whole batch once or twice a year (if that) but it's still something I'd like to be able to do in case I have to move the site to a different server, or there's a hard drive crash or etc. Basically what the script does is grab a whole bunch of information from a database and write the insert file. It does this for every single one. The problem of course, is that PHP by default does all this server-side, and then sends it to the browser. Because this process takes like ten or twenty minutes to do, the browser times out long before it's finished. Is there a way to get progressive output with PHP? Or do I need to re-do this in another language like Perl?

Real Time Echo'ing Of Var In A Loop
i have a big loop, and rather then waiting until its done for me too see what happened, every time it runs, how can i get the browser to echo the result, and proceed to keep running the loop. basically this loop takes a long time to finish, and i had to set my max runtime past 30 seconds. i guess incorporating a refresh of some sort like this would eliminate the need for the time extension too?

Real Time Form Update
i have a script that i wrote for my clan/guild/linkshell in this online game i play that keeps track of members, the points they receive from events, items etc. in the admin panel of the script where you can update peoples points i want to know if i can add a button or something similar that if you push it updates the points which is currently in another text box in the same form in real time. I'm sorry if i'm not being clear, what i'm trying to do it make it quicker to update a members points because usually after each event they receive either 10 or 20 so i want to add a button where if you push it then it will put 10 or 20 in the 'add' box in real time. right now when you edit a member it shows their current points in a text box and under that two text boxes, one if you want to add points and another if you want to subtract points. if this isnt possible then i assume that i'd have to make it update the points in the box and keep all the values from before and just reload the page with the new value inside the box. wow, i'm sorry if i'm not very clear, please ask questions if you dont understand what i'm trying to say.

How Can One Get Real Time Stock Quotes For An Online-community?

I only know of Deutsche Börse offering it for 1駨 Euro per month. That is too expensive for us.

Chat Function That Allows Users To Seek Help Via Live Chat
I found that some of these pre-made help desks also have a live chat function that allows users to seek help via live chat, similar to aim. (Once you log into the help desk at php live, click on the "launch request monitor window" to get a better understanding of what I am talking about.) Unfortunately, I showed this to my boss and he liked that idea. Why unfortunate? I have no idea where to start on this one! I have done several web apps with php and mysql, so I would say I have a fair grasp and understanding, but this one has me stumped. Has anyone done something similar to this or have an idea in which direction that I need to be going?

A Real Challenge For Real PHP Programmers
<?php /* A challenge to every PHP programmer.The one who's gonna solve this problem would be deemed as PSP(PHP Supreme Programmer).The problem is this : You have to write a script that displays a list of categories and subcategorieslike this one: <select name="category"> <option value="1">Main</option> <option value="2">Main > Computers</option> <option value="4">Main > Computers > Hardware </option> <option value="8">Main > Computers > Hardware > PC</option> <option value="7">Main > Computers > Hardware > Mac</option> <option value="9">Main > Computers > Hardware > Atari</option> <option value="11">Main > Computers > Hardware > PC > History of Pc</option> <option value="">etc...</option> </select> The categories and subcategories details are stored in these two tables in a MySQL database. -categories : the categories names and ids. -cat_relations : the relations between categories.It shows which subcategory belongs to which category. The belongings between categories can go very deep and the number of categories is unlimited. This script will create the two tables and fill them with sample data. All you need to do is to change the four variables below. You can send the script back to this email : yasbergy@yahoo.com. */ //Here starts the script. Please change the values of these variables to fit your settings $user = "prospective_PSP"; $database = "db"; $server = "localhost" ; $pwd = "" ; //Connection to the database that you created mysql_connect($server,$user,$pwd) ; mysql_select_db($database); //Creation of the two tables : categories and cat_relations $categories = " CREATE TABLE `categories` (`id` INT not null AUTO_INCREMENT, `name` VARCHAR(100) not null , PRIMARY KEY (`id`), INDEX (`id`), UNIQUE (`id`)) comment = 'The categories details' "; mysql_query($categories) ; $cat_relations = "CREATE TABLE `cat_relations` (`id` INT not null AUTO_INCREMENT, `daughter_id` INT not null, `mother_id` INT not null , PRIMARY KEY (`id`), INDEX (`id`), UNIQUE (`id`)) comment = 'Which category is the daughter of which category'"; mysql_query($cat_relations) ; //Filling the two tables with sample data $cats = array('Main','Computers','Countries','Hardware','S oftware','Programming languages','Mac','PC','Atari','Winamp','History of the PC','IBM','Components','High level','USA','NYC','LA','Manhattan','India','Winzi p'); for ($i=0;$i<count($cats);$i++){ $sql = mysql_query("insert into categories (name) values('".$cats[$i]."')"); } mysql_query("insert into cat_relations (daughter_id,mother_id) values (2,1),(3,1),(4,2),(5,2),(6,2),(7,4),(8,4),(9,4),(1 1,8),(12,8),(13,8),(10,5),(20,5),(14,6),(15,3),(16 ,15),(17,15),(18,16),(19,3)"); //Now you can have a look on them through phpMyAdmin ?>

Real Length Of Arrays
Sometimes, I want to know how many elements are really in an array (php3). The count() and sizeof() functions apparently return the number of non-empty array elements, and if you do a while loop checking for empty will stop on the first empty element. I have been using the following function: function truecount($theArray) { if (is_array($theArray)) { end($theArray); return key($theArray); } } but if the key is non-numeric, won't that trip me up? Anyone have a better solution?

Real IP Address From Behind Proxy Or NAT
How to get the real IP address of a user, not that of their proxy server or the external NAT address. I was quite sure that this wasn't possible without some kind of process getting the address on the client machine. I have suggested that these sites could be using Java to get the real IP address, however, I could be wrong and for me the script that I found always returns 127.0.0.1 . This suggests to me that any script attempting to obtain the hosts real IP address infarct rely s on the HTTP-X-FORWARDED-FOR header sent by the proxy server...

i have made a chat script that uses META REFRESHES to update from a flat txt file. this is very inefficient for both server and user. the problem is i can't think of any other way to do it. one way i can think of is to open sockets so that a server can look at the file and see if it has been changed. of course, i have no idea where to start, so instead i built a really bad script that was worse on the client (i.e. 100% CPU usage) but not so bad on the server. any ideas?

Chat

The second would be to keep open the connection in the hidden frame (so the page is never realy loaded). I would prever the latter, but don't know how one keeps open the connection. What happens if the user closes the browser?

PHP Template Redirecting To Real Video
I've developed a RealVideo content management system w/ PHP and MySQL. On the back end is a form that sends a Real Video file (.rm) and writes the filename to a database. On the front end is a PHP template that pulls the filename from the database and outputs a string that is read in by a Flash movie. The Flash movie reads in the file location and places HTML-encoded text inside a text field that says "Launch Video." All works fine -- the Flash movie launches the Real Video file, and the file plays correctly. There's only one problem: the Real Video doesn't stream. In order for a Real Server to stream a Real Video file, a "stub" file with the extension .ram needs to be placed in the root directory. The only content in these .ram files is a URL pointing to the actual .rm file, and it's written in this format: pnm://ra.domainName.com/realvideoFile.rm My problem: The form is sending a Real Video file and the receiving page is copying it to the server as well as inserting a record into my database, but it can't write a .ram file to the root directory because to do so I'd have to adjust permissions accordingly (PHP is part of group Apache). That's unacceptable; I won't adjust permissions on the root directory. My solution was to create a redirector that acts as the stub file: PHP Code:

Stripping Commas From Real Numbers
I have an HTML form in a PHP script which queries the user for a dollar amount of sales. If a user enters "1,000,000" rather than "1000000" for 1 million, PHP (or MySQL?) treats the commas as a decimal and "1" is entered in the database. A simple work-around is to simply advise the user "Please enter numbers only, no commas or $'s" but this seems awkward. Is there a built in function or another easy way to have commas and currency signs stripped out of form-entered data?
