PHPExcel_Shared_OLE_PPS_Root::save (   $filename)

Method for saving the whole OLE container (including files).

In fact, if called with an empty argument (or '-'), it saves to a temporary file and then outputs it's contents to stdout. If a resource pointer to a stream created by fopen() is passed it will be used, but you have to close such stream by yourself.

Parameters
string | resource$filenameThe name of the file or stream where to save the OLE container. public
Returns
mixed true on success
