Ajax Chat

Php based Ajax Chat. It's an easy to use ajax chat script, it has spam filter capability and it only needs 3 files (index.html, w.php and chat.txt) Index.html reads the content & sends your message to w.php. w.php writes the content and prunes it to $maxlines lines

Gear up for grub with a tripleheader of pigskin, including a meeting of brothers in Dallas. Everybody knows it's been a rough year for her, but find out who else had issues

i wonder if this would be easily intergratable with mysql or if a xml has to be used as an intermediate between the two.

Sept. 12, 2008, 9:41 a.m. - What

Doesn't this just hit the server repeatedly, polling for info? If so, what are the performance implications with say, 200 ish users (with wait at 800ms that means you are getting more than 200 requests every second).

Sept. 26, 2008, 4:23 a.m. - Swati

Wow ....Its Great!!!!

Nov. 16, 2008, 12:53 p.m. - majid

hi! i am majid my id is abdulmajid11@hotmail.com please guide me if i can get a asp.net virsion for this chat script.... i would be waiting for your response

Nov. 23, 2008, 1:39 a.m. - chris

as an answer to the speed question: the chat script got dugg and mentioned on wired last year and stayed up even on a medium-quality hoster without any problems... since the requests are small in size, it was able to handle a few hundret (or even more) users at once. and yes, you can use it in your blog, your homepage or whereever you want. just need to include the html tag and the javascript, and on the backend side the w.php and a writeable chat.txt.

June 15, 2009, 10:28 a.m. - Stéphane

Nice script but there is a bug with IE and I can't found where it is, surely in javascript somewhere : You can't type twice same thing. Ex: you send just the mord 'yes' then some others line and want to say 'yes' again, nothing happen... :(

June 16, 2009, 4:33 a.m. - Ameen Islahi

Not UTF-8???

Feb. 28, 2010, 11:05 a.m. - Eugene

Russians here??

Feb. 28, 2010, 2:07 p.m. - Eugene

I solved it for the Russian language. Should use the JS encodeURIComponent method - like this ajax_write("w.php?m=" + encodeURIComponent(msg) + "&n=" + encodeURIComponent(nick)); And you may write whatever necessary, charsets to hell... Are Americans going to win, you think???

April 22, 2010, 11:56 a.m. - peter

Sept. 23, 2010, 2:32 p.m. - namy

it doesn'tworks at all with firefox

April 1, 2012, 12:43 a.m. - Brandon

This ajax chat is very noob-like, but a good start for beginners. First off, why would you ever even consider returning the entire message log on every response???? Yeah, I'm using firebug :D Suggestion 1, load it and only return new content since load. Suggestion 2, If no message has been received in longer than 5mins then delay the checking a bit. Suggestion 3, with about 15 lines of code you could include HTML5 sounds (all major browsers) for user online, user offline, message send and message receive. TLDR; Do not use this chat in any kind of production. Only use it to learn how to make a proper chat.

Doesn't work in FireFox anymore. It used to work for me like a year ago. Is there a fix or reason why this script stopped working?
