Warning
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.
dbplus_curr() will read the data for the previous
tuple for the given relation, will make it
the current tuple and will pass it back as an associative array
in tuple.
The function will return zero (aka. DBPLUS_ERR_NOERR) on success
or a db++ error code on failure. See
dbplus_errcode() or the introduction to this
chapter for more information on db++ error codes.
