MP3文件持续时间PHP

Question

I worked with some mp3 files, and i needed to show duration of uploaded mp3 file, I used following: http://www.zedwood.com/article/127/php-calculate-duration-of-mp3 as told in question: PHP Function to get MP3 duration .

But now I'm facing a problem, there are some files which are not returning any file information. the array just contains following

Array (
    [Filesize] => 16756370,
    [Encoding] => Unknown
) 

As the "Encoding" is Unknown its not returning any data.

Answer 1

I found a great PHP library, getID3() , that works for VBR files as well.

You can find it right here; it's free and is being developed actively (latest version is from from February 2013):
