I have the following script, however the $song[x] does not seem to function?

the $currentlisteners and $maxlisteners varialbes are populated

What am I doing wrong?

PHP Code:

What is your Winamp/DSP combo input method?

Blind-Summit · 15th October 2003, 17:45

Winamp 2.91
SHOUTcast Source 1.8.2b
WWWinamp 2.5d

ADSL Modem 576/256
WinXp Pro SP1

As you see from the code, I pass my Ip to that NO-IP site, but I don't think this is the issue

Blind-Summit · 15th October 2003, 18:10

heh

sorted

I had enabled the titles but forgot to update my code.

How dumb do I feel

One last question tho,

can i include the php on a webpage, but not display the image. I then want to display the details into a table

ie <?php include "radioserver.php">

and then call the $song[0] into a <tr> </tr> set of tags for a table

Blind-Summit · 15th October 2003, 18:12

Last last question

what other things are passed to this php code?

what else can i display on my image? such a bitrate, server uptime, etc? or where can i look to find out?

And what is fart++ ?????

Thanks for your help tho, and bloody good site by the way, keep up the good work

Q: can i include the php on a webpage, but not display the image.
A: You'll need to diable the image generation

You may find it easier to have two sets of code. One for the image and one for website display.

**************************

Q: what other things are passed to this php code?
A: Since you're using 7.html (from the DNAS readme)

Quote:

To snag a quick list of listener counts, server state, bitrate, and current
title, use the URL http://yourip:port/7.html

For other XML information, you'll need to gather the XML statistics from the admin interface (from the DNAS readme)

Quote:

XML Statistics:

The SHOUTcast DNAS provides an internal mechanism for providing statistics
to external applications via XML, which is useful for providing live
information on your DNAS embedded in other webpages via PHP, Perl, or
other methods which can implement XML. Accessing this data is a bit tricky,
so it's briefly explained here:

XML pages should be called via:

http://yourip:port/admin.cgi?pass=yourpass&mode=viewxml&page=0
http://yourip:port/admin.cgi?pass=yourpass&mode=viewxml&page=1
...

Where:
Page 0 is all DNAS data
Page 1 is only Main data
Page 2 is only Webdata Table
Page 3 is only Listener Table
Page 4 is only Songhistory Table

Your XML parser MUST send a User-Agent: HTTP header containing the
word "Mozilla" in order for the DNAS to recognize it as something
other than a listener.

Q: And what is fart++ ?????
A: I have gas
