Dropbox and Live Mesh are common network storage services that can share and synchronize files on multiple computers. Microsoft's Live Mesh provides 5 GB space, the initial free space provided by Dropbox is 2 GB, which can be increased to 5 GB by invitation. The two network synchronization software have their own advantages, but I feel that Dropbox is more useful

In this article, we will explore accessing files in the Dropbox account by building a simple Dropbox API for the client. The client will perform some basic operations, such as authentication, listing files, uploading and downloading files.For short and readable articles, I will keep the code to a minimum, instead of providing complete code on your PHPMaster GitHub. To run the code, you need to support curl,
