Build Identifier:

we notice that a "PHP Notice" was rised every time the mapi_execute() returns a FALSE

Reproducible: Always

Only variable references should be returned by reference in .../ on line 96) due to the by reference return behaviour of the function;
we suggest to remove that behaviour since it does not increase performance (see
Finally note that pass-by-reference has been deprecated (Deprecated: Call-time pass-by-reference has been deprecated in php_monetdb.php on line 302)

Changeset 6c59acf6021e made by Fabian Groffen in the MonetDB repo, refers to this bug.

For complete details, see http//devmonetdborg/hg/MonetDB?cmd=changeset;node=6c59acf6021e

Changeset description:

mapi_execute: don't return a reference, since we can return FALSE

Bug #2939, PHP spits a notice mapi_execute tries to return FALSE.  Since
there is no performance improvement by actually returning a reference,
just don't do it.
