Last.fm API - 跟踪持续时间

Question

I'm using the Last.fm API and I stuck on something seemingly fairly simple.

One of the responses is the duration. Which is returned as:

222000

But how do I format (in PHP) this to look like

MIN:SEC
3:42

Answer 1

It looks like the duration is in milliseconds. Just divide by 1000 to get the number of seconds.
