Bug #63916 PDO::PARAM_INT casts to 32bit int internally even on 64bit builds in pdo_sqlite
Submitted: 2013-01-06 05:20 UTC Modified: 2013-01-14 17:00 UTC

Status: Closed Package: PDO related
PHP Version: 5.4.10 OS:
Private report: No CVE-ID: None

Description:
------------
Binding a PDO parameter with pdo_sqlite on 64bit builds with PDO::PARAM_INT 
forces the param to be cast internally to an int. This means 64bit ints will be 
cast down to 32bit ints internally even if PHP was compiled against a 64bit arch.

Test script:
---------------
$num = 100004313234244; // notice this exceeds 32 bits
$conn = new PDO('sqlite::memory:');
$conn->query('CREATE TABLE users (id INTEGER NOT NULL, num INTEGER NOT NULL, PRIMARY KEY(id))');

$stmt = $conn->prepare('insert into users (id, num) values (:id, :num)');
$stmt->bindValue(':id', 1, PDO::PARAM_INT);
$stmt->bindValue(':num', $num, PDO::PARAM_INT);
$stmt->execute();

$stmt = $conn->query('SELECT num FROM users');
$result = $stmt->fetchAll(PDO::FETCH_COLUMN);

printf("Expected: %d Received: %d\n", $num, $result[0]);

Expected result:
----------------
// expected to output
Expected: 100004313234244 Received: 100004313234244

Actual result:
--------------
// instead we get output of
Expected: 100004313234244 Received: 294714180

Because we're currently running 3 branches I've sent the PR for this to master 
and I'm asking for it to be merged into 5.3.NEXT, 5.4.NEXT, and 5.5.NEXT 
respectively to maintain consistency.

This seems to be a regression from the PHP-5.2 branch as well. After testing on PHP-
5.2,5.3,5.4,5.5,and master branches I found that the issue did not exist back in ext/sqlite2 
as string casting was done instead of using integer types. The issue probably was over looked 
when the sqlite3 driver was ported in to replace the old ext/sqlite2.

Regression results:
