Description
string 
com_create_guid ( void  )
     Generates a Globally Unique Identifier (GUID) and returns it as a string.
     A GUID is generated in the same way as DCE UUID's, except that the
     Microsoft convention is to enclose a GUID in curly braces.
    
     See also uuid_create() in the PECL uuid extension.
