Retrieving information from ffmpeg shell_exec command

i am doing the following

$output = shell_exec('/usr/local/bin/ffmpeg -i intro.mp3 2>&1'); 
echo "<pre>$output</pre>";

This outputs

    Stream #0.0: Audio: mp3, 44100 Hz, stereo, s16, 160 kb/s
At least one output file must be specified

i want to get the information to insert into a database album,artist,genre,title etc

But all seperately

i can get them by doing the following

$output = shell_exec('/usr/local/bin/ffmpeg -i intro.mp3 2>&1'); 

$edit = explode('  ', $output);
$edit = implode("@", $edit);
$edit = explode(':', $output);
echo "<pre>";
print_r($edit);
echo "</pre>";

then running 

<?php echo $edit[9]; ?>

etc

but this seems like a really bad way and annoying way to get values and sometimes the output is slightly different which messes with the outputs.

Whats the best way to do this or am i stuck doing this?

There is a better way to retrieve metadata using ffmpeg.

1. Create a new ffmpeg_movie object e.g

$movie = new ffmpeg_movie(String path_to_media, boolean persistent);

2. Start getting metada like so:

$movie->getAuthor();
$movie->getGenre();
$movie->getAlbum();

List of what's available at ffmpeg-php API documentation.

3. Celebrate good times.
