PHP Function to get MP3 duration

Question

Is there any PHP function that will give me the MP3 duration. I looked at ID 3 function but i don\'t see any thing there for duration and apart from this,id3 is some kind of

Answer 1

The MP3 length is not stored anywhere (in the "plain" MP3 format), since MP3 is designed to be "split" into frames and those frames will remain playable.

If you have no ID tag on which to rely, what you would need to do (there are tools and PHP classes that do this) is to read the whole MP3 file and sum the durations of each frame.
