load local mp3-files

[opus15]

I'm not too fluent i php, so this may be ridiculously simple;

 

My php project is a sort of database of my collection of mp3 files. They are all stored on my hard drive/external hard drive (C: and E:). The problem is how to load these files from the php application (running on apache server) - the project is going to stay on my pc, not to be uploaded to a different server - I'm guessing the problems with the server, finding c: ?

I'll be using a javascript to play the files, or just embed that Quicktime thing.

 

This does not work:

 

$fil2 = "'file:///C:/RadioDB/2-4 Murder Unprompted.mp3'>" ;

 

or this:

<a href='http://C:\RadioDB/2-4 Murder Unprompted.mp3'>

 

Any help appreciated!

Thanks ignace!

Your code get met a lot closer to what I want, but not quite there...

 

The $directory and $file works fine. The $fh gives me (when I echo it) a Resource id - is it this I'm going to open/play the file with?

 

 

BTW, I've tried to implement the javascript for playing mp3 from this site:

http://www.oreillynet.com/pub/a/oreilly/digitalmedia/2006/05/31/build-a-better-web-audio-player.html?page=2  (the "BatmoAudioPop.js")

 

(This method works great - when I try it on a mp3 file stored in the same folder (easyphp/www/myfolder/) as my php application).

Yeah you actually need recursion to go through the entire directory structure capture each and every mp3 file and read it's ID3

[ignace]

function scandir_r($directory) {
    $mp3files = array();
    if (!is_dir($directory) || !is_readable($directory)) return $mp3files;
    $files = scandir($directory);
    foreach ($files as $file) {
        $fullpath = implode(DIRECTORY_SEPARATOR, array($directory, $file));
        if (is_dir($fullpath)) {
            $mp3files += call_user_func(__FUNCTION__, $fullpath);
        } else if (preg_match('/\.mp3/', $file)) {
            $mp3files[] = $fullpath;
        }
    }
    return $mp3files;
}

$mp3files = array();
$directories = array('..');
foreach ($directories as $directory) {
    $mp3files += scandir_r($directory);
}

print_r($mp3files);

 

Edit: I haven't tested this. I just wrote this out of the top of my head. If you have a serious amount of mp3 files your script may time-out and you may want to look at other algorithms available.

Thanks again, ignace!

You're right about the time-out, but my biggest problem is that I don't quite understand what your last suggestion will do - I'm not that good at php...

Will the $mp3files function return a filepath that I can use (with the javascript, for example) ?

Yes it will return the full path to the file but you won't be able to use this with JavaScript.

Here's the code that I was playing with

        }
    }

It works

My only problem now is to find a way to play the mp3-files, either with a javascript or the Yahoo Media Player, or whatever works. Anyone any ideas?

I would go for the Yahoo Media Player
