dbplus_open -- Open relation file
( string name )
This function is
EXPERIMENTAL. The behaviour of this function, the
name of this function, and anything else documented about this
function may change without notice in a future release of PHP.
Use this function at your own risk.
The relation file name will be opened.
name can be either a file name or a
relative or absolute path name. This will be mapped in any case
to an absolute relation file path on a specific host machine and
On success a relation file resource (cursor) is returned which must
be used in any subsequent commands referencing the relation.
Failure leads to a zero return value, the actual error code may
be asked for by calling dbplus_errno().
