Description:
------------
The documented behavior of oci_fetch_all() says it will return FALSE on failure.  However, it appears to return 0 instead.

Presumably you want to either correct the documented behavior of oci_fetch_all(), or perhaps remove "failure behavior" from the its doc completely.

Test script:
---------------
$stmt = oci_parse($conn, $sql);
oci_execute($stmt);
$rows = oci_fetch_all($stmt, $ret, 0, -1, OCI_FETCHSTATEMENT_BY_ROW);
var_dump($rows);


Expected result:
----------------
Warning: oci_fetch_all(): in ... on line ...

bool(false)

Actual result:
--------------
Warning: oci_fetch_all(): in ... on line ...

int(0)
