Grabbing Information from a Remote MP3 File

Question

I'm trying to extract MP3 ID3 Tag information from any remotely hosted mp3 file via PHP. I've tried several times with fread and fseek to grab the last 128bytes of the file and extract the tag information...but had no success.

Here's and example of what I want to do: http://www.digitalcoding.com/tools/read-remote-mp3-avi-file-id3-information.html

Any tips or code snippets would be appreciated :)

Answer 1

With HTTP you'd download a range of data from the resource. You can pick an arbitrary range and it can even consist of multiple parts like "XY" or "XY,AB" etc.

Servers however don't always support that and then you'll be served the full file instead.

When using something like curl, you can use its CURLOPT_RANGE option (or the command line tool's -r).
