 $encoded= base64_encode($contents);

 $encode = "'data:audio/midi;base64,".$encoded."=='";

Answer 1

Guessing you're on a linux machine... The simplest way is to play it with timidity and pipe the output ffmpeg:

timidity song.mid -Ow -o - | ffmpeg -i - -acodec libmp3lame -ab 64k song.mp3

Answer 2

If you're using Linux, use avconv instead of ffmpeg because ffmpeg is being deprecated:

timidity input.midi -Ow -o - | avconv -i - -acodec libmp3lame -b 64k output.mp3

Or lame:

timidity -Ow -o - input.midi | lame - output.mp3
