Simplistic Winamp 'Now Playing" image

[NightStorm]

This will require 3 files, all in the same directory. So, of course you will need access to the space, you will need access to create an .htaccess file (if worse comes to worse, your host may place the file for you), and you need php access.
First, create an .htaccess file in the directory, and enter in the following:

Code: Select all

AddType application/x-httpd-php jpg
AddType application/x-httpd-php png
AddType application/x-httpd-php gif

Next, create a file called sig.jpg (or whatever else) and place ONLY this code in it:

Code: Select all

<?php include('sig.php');?>

Now comes the fun part. Create a file called 'sig.php', and add this code to it... be sure to edit it to your liking (as I said, this is simplictic):

Code: Select all

<?php

I tried to comment through the file as much as I could, just so you know what it is doing, and what can be easily edited... but this should give some people a head start on what they need to do to make this, or another dynamic image. The key part is the htaccess file, as it tells the system to read the php inside the image as php code, instead of as a corrupt image.
The nicest thing to this, is that you do NOT need admin access to the Shoutcast server to set this up... something that sets it apart from other options.

Right now (well, not at this second, but in general) I'm working on using a background image with it, or at the very least aligning it better (like the one in my sig). I was kinda in a rush, as I had people pounding on the door and such (something about a meeting I was supposed to be at... slackers).

Adding a background image... you'll want to play with the text alignment to make it fit with whatever background you chose, though

Code: Select all

<?php 

header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");  //Will never cache the image
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); //Set date to creation (viewing) of file
header("Cache-Control: no-store, no-cache, must-revalidate"); //Do Not Cache, Store, or otherwise view older copies of the image
header("Cache-Control: post-check=0, pre-check=0", false); //Ditto
header("Pragma: no-cache"); //Duh
Header("Content-type: image/jpeg"); //This is to create an Image, so read it as such

$im = imagecreatefrompng("sc_back.png"); // This will be the background image

$host = "radio.lethargy.ws"; //Shoutcast Host (or IP)
$port = "8000"; //Shoutcast Port
$listenlink = 'radio.lethargy.ws:8000/listen.pls'; //URL to the listen link, without the http://

$fp = fsockopen("$host", $port, &$errno, &$errstr, 30); //Opens a socket to the Shoutcast server
if(!$fp) { 
$success=2;
} 
if($success!=2){
fputs($fp,"GET /7.html HTTP/1.0\r\nUser-Agent: XML Getter (Mozilla Compatible)\r\n\r\n"); //Grab 7.html (contains all the needed data)
while(!feof($fp)) {
$page .= fgets($fp, 1000);
}
fclose($fp);
$page = ereg_replace(".*<body>", "", $page); //extract data
$page = ereg_replace("</body>.*", ",", $page); //extract data
$numbers = explode(",",$page); //extract data
$currentlisteners=$numbers[0]; //How many connections are in use
$connected=$numbers[1]; //How many unique listeners

if($connected==1)
$wordconnected="yes";
else
$wordconnected="no";
$peaklisteners=$numbers[2]; //Set a variable for the Peak Listeners
$maxlisteners=$numbers[3]; //Set a Variable For The Max Listeners (total available spaces)
$reportedlisteners=$numbers[4]; //How many people are listening
} 

$text_color1 = ImageColorAllocate($im,255,255,255); //Set Text Color 1
$text_color2 = ImageColorAllocate($im,0,0,0); //Set Text Color 2 (Used if you will be using more than one color)

if($success!=2 && $connected==1){ //If we are connected, proceed... or else, jump to else
 $song=explode(" - ",$numbers[6]);
 $string1= $numbers[5]."kbps With ".$currentlisteners." Listeners (".$maxlisteners." Slots)"; //First Line Of Text... can be anything you want
 $string2= $song[1]." ".$song[2]." ".$song[3]." ".$song[4]; //Second Line Of Text
 $string3= $song[0]; //Third Line Of Text
}
else { //If we are not connected, proceed
 $string1= "The Radio is currently Offline"; //First Line To Display When Radio is Offline
 $string2= "No Song Currently Playing"; //Second Line To Display When Radio is Offline
 $string3= "No Song Currently Playing"; //Third Line To Display When Radio is Offline
}

ImageString($im,5,187,27,$string1,$text_color1); //Set The First Line Of Text On The Image
ImageString($im,5,119,48,(substr($string2, 0, 40) . "..."),$text_color1); //Set The Second Line Of Text... after 40 characters, cut off with ...
ImageString($im,5,75,70,$string3,$text_color1); //Set The Third Line Of text
ImagePng($im); //Display The Image
imagedestroy($im); //Remove The Image From Memory
?>

Awesome!
How long did that take you?

[NightStorm]

With google, babelfish (most of the examples I found were not in English) and php.net?
About an hour.
Setting up my sig? ABout 10 minutes, once Jeremy sent the template for the background. The hardest part is in figuring the alignment out for the text.
