MFH. Protect against underflow - refs http://pecl.php.net/bugs/bug.php?id=5193

Fixed memory leak.

add sanity checks

- Add missing part to make colon in parameter binding optional

this looks like a much better fix for refcounting/shutdown in lazy objects.

fix leak (ugh, this nuance gets me every time)

Fixes #33785 for me

make a start on a debugging function.

remember ? -> :pdox mapping so that binds by position can be mapped to names if required.

expand oracle null handling compatability by offering the ability to convert
NULLs into empty strings as well as the other way around. It still doesn't
help a great deal in the long run, but

expand oracle null handling compatability by offering the ability to convert
NULLs into empty strings as well as the other way around. It still doesn't
help a great deal in the long run, but at least the option is there.

Make sure hash tables are nulled out to avoid double freeing them.

fix a segfault with the following script:

Added:

proto bool PDOStatement::closeCursor()
Closes the cursor, leaving the statement ready for re-execution.

The purpose of the function is to free up the connection to the server so that
other queries may be issued, but leaving the statement in a state that it can
be re-executed.

This is implemented either as an optional driver specific method (allowing for
maximum efficiency), or as the generic PDO fallback if no driver specific
function is installed.

The PDO generic fallback is semantically the same as writing the following code
in your PHP script:

do {
while ($stmt->fetch())
;
if (!$stmt->nextRowset())
break;
} while (true);

For named-parameter-to-named-parameter rewrites, we need to map the original
names to the new names.

Fix a shutdown order issue I saw in the pgsql driver. Hope this doesn't mess
up something in the OCI driver; I think I've been here before.

Add a PDO_ATTR_STRINGIFY_FETCHES attribute, which is used to convert integer or
floating point values into strings during fetch. This is a compatibility hack
for drivers that return native types rather than string representations.

We use this flag in the test suite to persuade postgres tests to pass.

Return an empty array rather then FALSE in fetchAll() on no results.

Fix bug in bindColumn() for drivers that implement native prepared statements
and that use the PDO rewriter to handle non-native parameter syntax.

Fixed memory leaks

Add PDO_FETCH_NAMED; closes PECL #4641 by providing a way to access columns
by name, even when multiple columns have the same name:

$sql = "SELECT 1 a, 2 a, 3 b, 4 c, 5 d, 6 c, 7 a";

by name, even when multiple columns have the same name:

$sql = "SELECT 1 a, 2 a, 3 b, 4 c, 5 d, 6 c, 7 a";
echo "$sql\n";
print_r($db->query($sql)->fetchAll(PDO_FETCH_NAMED));

Array
(
[0] => Array
(
[a] => Array
(
[0] => 1
[1] => 2
[2] => 7
)

[b] => 3
[c] => Array
(
[0] => 4
[1] => 6
)

[d] => 5
)
)

Also added two new attributes for use at prepare time;
PDO_ATTR_FETCH_TABLE_NAMES and PDO_ATTR_FETCH_CATALOG_NAMES instruct the driver
that the names of the columns that they return to PDO should include the table
and catalog names respectively. Both attributes may be used together or
independently. The catalog, table and column name components should be
separated by a . character.

Fixed memory leak on PDO_FETCH_OBJ.

Fixed zval_ptr_dtor(&return_value) on uninicialized zval

As per PDO meeting on PHP|Tropics fetchSingle is being renamed to
fetchColumn and now supports specification of the column to retrieve.

removed debug code.
