Description:
------------
Integer on firebird is treated as a 32 bit int and int64 is used as a 64 bit integer.
In the pdo_firebird driver INT64 is not implemented and LONG (int32) is treated as a long integer. On an x86_64 machine this means that a SQL_LONG doesn't honor the bit-sign in a value and INT64 doesn't return anything.

This patch should fix this value for x86_64 systems while leaving x86 systems unchanged.

Test script:
---------------
any firebirdSQL database with a integer field containing a negative value.
retrieve the value with the pdo_firebird driver on a 64 bit machine and echo it to the screen.

Expected result:
----------------
negative values with integer and should be returned as a negative number.

Actual result:
--------------
negative values are returned as their unsigned counterpart.

LL_MASK it should be already be "l" see the php_pdo_firebird_int.h:# define 
LL_MASK "l"

So in the in the slprintf 
slprintf(*ptr, CHAR_BUF_LEN, "%" LL_MASK "d", *(ISC_INT64*)var->sqldata);
should be replaced with 

slprintf(*ptr, CHAR_BUF_LEN, "%" "l" "d", *(ISC_INT64*)var->sqldata);

I will check and create a test for 5.3.x

why this patch only partially accepted? still not working on x86-64
$q="select * FROM RDB\$DATABASE";
$q="execute block
returns (
rI integer)
as
begin
rI= -1;
suspend;
end";
$res=$pdo->dbExecute($q);
print_r($res->fetch());

outputs
Array
(
    [RI] => 4294967295
    [0] => 4294967295
)
istead of
Array
(
    [RI] => -1
    [0] => -1
)

Why are many serious bugs of pdo.firebird not revised?
I cannot use ORM such as DBAL in Firebird.

may be it's time to move to Java with native POJO ? )

bug and patch are three years old, looks like this is not need to anybody

I am running into the same problem and it seems that it's still not fixed (at least I do not find any relevant changes in the repository).

Maybe Firebird is not as popular as other DBMS, but I cannot imagine that nobody needs negative values in 32bit-integers.

I am such dissapointed: the problem is still not fixed in current PHP 7.0 RC6 :-(

Please, please fix it...

Does this confirm that nobody actually uses Firebird? For a bug like this, which effects simple day to day operations such as wanting to use a negative number, to remain open, despite a patch having been offered, for this many years, I find incredible.

I ported code from ibase specific stuff to PDO in anticipation of having to ditch Firebird for other reasons. This confirms its fate.

The commited patch doesn't work. The change bellow appends "ld" to the number.

-					*len = slprintf(*ptr, CHAR_BUF_LEN, "%" LL_MASK "d", *(ISC_INT64*)var->sqldata);
+					*len = slprintf(*ptr, CHAR_BUF_LEN, "%ld" LL_MASK "d", *(ISC_INT64*)var->sqldata);

I think just the single change in the earlier patch is required. At least that worked for me.
 [2015-12-04 10:34 UTC] slavb18 at gmail dot com 
we are using php5-bug60052.patch with single change since 2013-09-26, no problems
 [2015-12-04 16:48 UTC] mariuz@php.net 
I have reverted that patch , it wasn't needed
