Description
OCI-Collection 
oci_new_collection ( resource connection, string tdo [, string schema] )
      Allocates a new collection object. Parameter tdo
      should be a valid named type (uppercase). The third, optional parameter 
      schema should point to the scheme, where the
      named type was created. oci_new_collection() uses
      the name of the current user as the default value of schema.
     
     oci_new_collection() returns FALSE on error.
    
Note: 
      In PHP versions before 5.0.0 you must use ocinewcollection() instead. 
      This name still can be used, it was left as alias of
      oci_new_collection() for downwards compatability. 
      This, however, is deprecated and not recommended.
