There are quite a few previous threads on chat systems for PHP. Click [URL="http://www.daniweb.com/forums/search.php?searchid=17166467"]here[/URL]

Does your php module have a name that ends in .php? Is your localhost running when you try this. If so, what did you install for a LAMP stack? Did you run some sort of simple "hello World" php program at the start to verify that your installation was functioning …

You need more than php to make this work. This [URL="http://stackoverflow.com/questions/223983/live-video-streaming-with-php"]link [/URL] provides a discussion with some additional links for more info. If you want to stream to many end points then you need something fairly sophisticated. If you need something smaller scale with a closed audience, then you could …

If you want to do web programming, then PHP is a good choice for a bunch of reasons. Besides being pretty easy to learn, it is supported on almost all servers, it has a large community with lots of open source code and lots of help. You can do almost …

If you want help, then you need to demonstrate some effort and provide an initial design with some specific questions. If you can't get that far on your own, then maybe you don't deserve to graduate! There are lots of reservation systems out there and that probably includes some open …

There is a Drupal chat module: [URL="http://drupal.org/project/chatroom"]http://drupal.org/project/chatroom[/URL] There are simpler CMS's than Drupal to implement and maintain. You might want some of the CMS functionality, now or in the future. If you start with a separate Chat app, one option is to embed the Chat application within a CMS page …

This article looks at some of the strengths and weaknesses of the different options. You need to consider Javascript solutions like JQuery as well. In part, it depends on what you're going to do with it. Mobile apps are becoming a bigger part of the picture but that may not …

I don't think that you can initiate it from the user end with HTML (without two forms). You might be able to do it with Ajax. You could possibly transfer it from the prime (external) server to your server after it is received on the prime server.

I have done quite a bit of work with uploading and reading data from Excel and the tool that I have used is the [URL="http://code.google.com/p/php-excel-reader/"]php-excel-reader[/URL]. This lets you access the rows and columns in the spreadsheet (after you upload it). It should work just fine for what you need to …

Why not use something that already exists like [URL="http://pixlr.com/"]Pixlr[/URL].

You could start with this: [URL="http://www.fuzzy-logic.com/"]http://www.fuzzy-logic.com/[/URL] Here are some classes that may be useful when implementing: [URL="http://yawf.org/phpdocs/Sure/_plugins---Logic---FuzzySure.php.html"]http://yawf.org/phpdocs/Sure/_plugins---Logic---FuzzySure.php.html[/URL]

As you seem to already recognize, when you include the module with the arrays, you are getting a fresh copy every time. If your intent is to pass these arrays around and update them, then you are right again, using session variables would be the best way to do it. …

You don't really need the action on the form since it defaults to itself anyway. Re-direct usually means something specific and that isn't what you need to do for this. Before it displays the form, your program needs to check the post variables ($_POST) to see if something was posted …

Assuming that PHP and Apache are working correctly (and they may not be) then this is likely caused by trying to run PHP code from a module that doesn't have a .php suffix. For this reason or because of your setup, the module isn't being processed as a php module.

I've had a problem the last couple of days that the Daniweb drop-down menus don't drop down under Chrome. I have to click on the category and open the page to get at the secondary categories. Never had this problem before and it still works ok for me under IE. …

Could this be a limit imposed by your web host?

Maybe you should explain why you need to do this. Normally, the session will terminate automatically when the browser is closed.

A blank page usually means that you had a syntax problem and the program didn't run. If you use an editor that has built in syntax checking (like Netbeans) it will help you find these errors. Indenting your code makes it easier to see some kinds of problems visually. In …

You could explode the string using the ":" as the delimiter. This will give you an array with two entries. Take the first entry, multiply it by 60 then add the result to the second entry and you're done.

You haven't provided a definition of the scope of the project or any limitations. Some of this could be done by implementing an existing open-source online training system but if the requirement is that you develop the solution yourself then you are potentially looking at a very significant project that …

I doubt that anyone can help you without more info. Especially if this is a homework project, we need to see some code and a demonstration of your effort. If you can identify a specific section of your code that isn't doing what you want it to do (and post …

I tried it and I had the same problem. I checked php.ini and I had the extension disabled (php_spl_types.dll) so I changed that but it still didn't work. I checked and the extension is in the Ext directory. It should work but it is still giving the same error.

"Are space and time fundamental concepts or are they approximations to other, more subtle, ideas that still await our discovery?" "What is the difference between the sigmundoscope and the sigmoidoscope? Less cryptically, how is everyday narrative logic different from extensional mathematical logic? "Is there, or should we expect, a fracture …

First: You need to include your code using code tags. Second: In this case the code may not matter a lot. It may be the result of what you installed and how you have installed it. If you want to get PHP (and MySQL) working, the easiest way is use …

How about [URL="http://www.a-z-dictionaries.com/Open_Source_Dictionary_Downloads.html"]http://www.a-z-dictionaries.com/Open_Source_Dictionary_Downloads.html[/URL] or this [URL="http://yeelou.com/huzheng/stardict-dic/lingvo/"]http://yeelou.com/huzheng/stardict-dic/lingvo/[/URL]

Here are a couple of links to comments about the Google changes. In theory, the changes were aimed at so-called "content farms" like eHow but they seem to have cut a wider swath than that. From early reports, it isn't just low-quality sites that are getting hit. That's the problem …

There might be another way but the classic way of handling a sequential file is to write a new copy (and then replace the old copy with the new one at the end). A CSV sequential file isn't a database and it isn't meant to handle random reads and writes. …

You need to talk to HostMonster. I suspect that you won't be able to do it but you won't know unless you ask.

If you are at the stage of planning your thesis, haven't you already done some sort of web-based development? How can you get through a Software Engineering course without having done this? I say this because your first choice for developing a web-based solution should be whatever web development language …

There are different ways to tackle this: 1. Find an Open Source system that is Reasonably Good Install it and live with whatever it provides. If you have the skills and time, you can modify / extend it. I found one called [URL="http://www.jobberbase.com/"]JobberBase[/URL] that you may want to look at. …

The link address isn't valid.

If you main objective is to get something working quickly, then I'd start with a search to see what open source solutions are available. [URL="http://tinyurl.com/42aebds"]http://tinyurl.com/42aebds[/URL] Even if it is homework, looking at existing systems will still give you a head start.

I haven't used it but you may want to have a look at this one. Not PHP but can be used in a PHP environment. If this doesn't fit, do a search: there are other choices. [URL="http://encodable.com/filechucker/"]http://encodable.com/filechucker/[/URL]

I did this myself and you can do the same. Version 1 was from CSV and for that I did a manual save to CSV from Excel first. Versions 2 and 3 do it directly from the Excel spreadsheet. This, in the end is a whole lot simpler than converting …

If you are running this locally on a Windows system, then there are probably many ways to do this. I use a Basic-like scripting language called [URL="http://www.autoitscript.com/site/autoit/"]Autoit[/URL] for this type of work. It has good functions for reading and writing to Excel.

If OpenStreetMap has the level of info that you need, then that is probably your best solution. There is info [URL="http://wiki.openstreetmap.org/wiki/Deploying_your_own_Slippy_Map"]here[/URL] on how to deploy it.

The proper format would be: [code] foreach ( $_POST as $name => $value){something} [/code]

You can use: [code] $result = str_replace ("--","",$string); [/code]

I would echo the Select statement and try it in PHPMyAdmin and see if you get any results. If you do, then something is probably going wrong in the connect or select. If you don't, then you need to check the select and see what isn't matching up with the …

You are expected to make your best attempt at coding the solution and then posting some code if you have a problem. It isn't code-on-demand where you can just post a requirement. This isn't a very difficult requirement so if you have some programming skills, it shouldn't be a problem. …

I don't know if you will find this all packaged together. CMS's generally have dynamic menus and individual templates may have multi-level drop-down's built on top of that. If you do a search, you will find many JQuery drop-down menu solutions. If you do a search, you can also find …

I looked at SoftwareKey's website and I must admit that I found what they are offering to be a little bit unclear and pretty expensive. If I was going to sell some of my software, I would want to encrypt the code and have licensing options. I have used Armadillo …

Why don't you try [URL="http://code.google.com/apis/checkout/samples/Google_Checkout_Sample_Code_PHP.html"]the sample code [/URL]provided by Google?

Assuming that you are correctly displaying a white pixel, you might be pushing the limits of the monitor or more likely the human eye. You may need something larger than a single pixel in order to have the color clearly distinguished. I'm not a physics expert but remember than a …

I don't think anyone could provide anything other than speculation based on the limited information that you have provided. Whether additional workload such as a Cron job will affect performance will depend on how close to the limit of the server you are and how efficient the Cron jobs are. …

I think we'll need to see more of the code.

I think that you need to work on your debugging skills! $askingPrice is not the same as $asking_price. $askingPrice = 0 so the result is (1-0)* 100 = 100.

The data in the form will be passed to your purchase-process program. If you have any additional fields that you need to pass to that program then define them as hidden variables in the form (<input type=hidden...) and set the value and name.
