PHP - Adding subtitle to video in server side

Question

I wonder is there any method to merge subtitle to a video? both of them stored on the server...

I'm trying to create an apps that will have custom subtitle and then upload the subtitle to the server and merge it up with the video. Final step is to upload the video to the user's YouTube account.

Is there any way I could do this? With PHP alone maybe not, but extension/plugin maybe?

Thanks!
