Need PHP code that will run on hosted account. It would take following parameters:
Dropbox acount id
Dropbox account password
Local directory name
Given these parameters the code would compare contents of dropbox folder and local directory, if dropbox contains files not present in local folder they would be transferred to the local folder.
Dropbox cannot be installed on the hosted acoount (1and1 Bussiness), so this would require use of Dropbox API. If need more info, ask me.
