You could use an already existing platform to perform syncing. Most modern OSes support syncing, and you could also use external tools.

At the OS level:

• You can use rsync for *nix servers (plus, this has been ported to Windows too)
• Here's a way to do it between Windows servers

Using external tools:

• Goodsync enterprise
• Syncbreeze
• Under *nix, you could use rsync
• Here's a collection of programs (free and paid) to do this
• You could use a cloud-based service like Dropbox in all your servers

Using PHP:

• You could use librsync
• You could add an FTP/SSH server to each one of your distributed servers. Once a file is uploaded to one server, it can be uploaded via FTP to the others. PHP includes functionality for FTP - check the FTP section in the PHP handbook.
• Use FXP to transfer files between servers. The KioobFTP class can be used for this, as it implements FXP transfers
