pdo_firebird: "RETURNING" queries/closeCursor (#43246/43271)

Hi! According to the archive, this might be the list for concrete diffs - if not, please excuse me. I tried pdo_firebird (CVS PHP_5_3) and quickly ran across to bugs: a) RETURNING queries fail pdo_firebird - against the published docs - wants to return stored procedure return values by the "execute" call. As it is, RETURNING queries (for the lower level library) go in the same bucket; big nono. My proposed change removes "special" handling of stored procedure calls alltogether - as it seems not only undocumented, but against the docs. As a "side effect", RETURNING queries work again. b) PDOStatement->closeCursor not implemented Whenever I tried to re-use a prepared statement, I got an error msg about reusing an open cursor. As it seems, mere cursor closing is not currently implemented (discarding the statement closes the cursor). My proposed change adds a minimal "cursor_closer". Please excuse form and/or function of my diffs (or human language mistake). I'm neither a C nor a PHP guru. Nevertheless I humbly present those for your consideration. HPO
