Hello I am trying to create an audio streaming flash file. I will be using php, flash and mysql.

I have created a music page and if you click on certain artist, the choosen mp3 track will be played . So if you click on
(EG: musicplayer.php?id=2) then it will grab the mp3 link and use that to select the mp3 in the directory and play it. I have googled this and have had a difficult time doing this. I stumbled on this tutorial which introduced "Mediaplayback" I would die to use this component but it askes for the URL of the mp3 track. I would like to know if its possible to create a simple txt (php perferrably) file and it can grab the information from the txt file and store it into the url of the Mediaplayback so then it can playback the mp3 file. If this is possible plz plz reply back. I really need to know this.

there are several options on how to do it. They all have 1 thing in common, that is passing the id to the swf object (via flashvars in html, or via LoadVars in flash)

the flashvars works like this:

HTML Code:

<object etc="...">
<param name="flashvar" value="id=<?=$_GET['id'];?>" />
<embed etc="..." ></embed>
</object>

the LoadVars work completely different, as the call a php page from within flash. This page will then send the id to flash. Here's a basic code:
The Flash:

var lv = new LoadVars();
lv.load("http://myurl.com/getid.php");
lv.onLoad = function(){
  if(this.id != ""){
    //do stuff with the id
  }else{
    //invalid id specified
  }
}; 

The php (getid.php):

PHP Code:

<?php
echo "&id=".$_GET['id'];
?>

When you use this, flash now nows what the id is. You can do a very similar thing to retreive the url. There are 2 options:
1. You receive the id in flash, you request another php page which will send the url
2. you automaticly send the url, and forget about the id

both are not that hard to write. The only difference is that you will have to send some extra data to php when you first retrieve the id.
Here's a sample code to get the url instantly:
The Flash:

var lv = new LoadVars();
lv.load("http://myurl.com/geturl.php");
lv.onLoad = function(){
  if(this.url != ""){
    // do stuff with the url
  }else{
    // invalid id specified
  }
}; 

The php (geturl.php):

PHP Code:

<?php
// assuming you are using a textfile with the id corresponding to the line number on which the url is located in a text file:
$contents = file("the_url.txt");
if(array_key_exists($_GET['id'], $contents)){
  echo "&url=".$contents[$_GET['id']];
}else{
  echo "&url=";
}

Hope this helps you out. if it doesn't let me know, i'll try to explain more. Also take a look at the Loadvars page on livedocs
