Summary: All ODBC Queries Return INTs as Strings For Multiple
ODBC Drivers
Status: Not a bug
Type: Bug
Package: ODBC related
Operating System: SUSE SLES 10 SP2
PHP Version: 5.3.6

I have no idea why this bug is closed as bogus.
The current behavior is wrong for many reasons:
- Higher memory usage (can be problematic with big datasets)
- This forces one to use is_numeric instead of is_int, is_float, etc (much
slower)
- Removed the option for strict comparison: "1" === 1 => false

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php
Most database layers convert numeric values to strings to preserve their
precision as PHP does not support all numeric precisions which a database might
(i.e. 64 bit integers). Since strings may be silently converted to numeric in
PHP ("1" + 2 = 3), this should not pose too much of an issue.

Description:
------------
odbc_* and PDO ODBC functions are each returning SQL integer values as PHP
strings. However, SQL NULL values properly appear as PHP NULL values.
I have tested against multiple ODBC providers (FreeTDS and iSeries Access for
Linux).
System:
SUSE Enterprise Linux Server 10 (SP2) - 32bit
Linux dev-webhost1 2.6.16.60-0.42.5-default #1 Mon Aug 24 09:41:41 UTC 2009
i686
i686 i386 GNU/Linux
UnixODBC
PHP 5.3.6 from source
./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-
mssql=/usr/local/freetds --with-ldap --prefix=/usr/local/php5 --with-config-
file-
path=/usr/local/php5/etc --enable-sockets --enable-soap --with-openssl --with-
unixODBC=/usr --with-gd --with-jpeg-dir=/usr/lib --with-pdo-odbc=unixODBC,/usr
Test script:
---------------
1. odbc_* against FreeTDS to SQL Server 2008:
$odbc = odbc_connect('hpsql3','--censored--','--censored--');
$or = odbc_exec($odbc,'SELECT 1');
var_dump(odbc_fetch_array($or)); // array( string "1" )
2. odbc_* against iSeries Access for Linux to AS/400:
$odbc = odbc_connect('iSeriesDSN','--','--');
$or = odbc_exec($odbc,'SELECT 1 FROM SYSIBM.SYSDUMMY1');
var_dump(odbc_fetch_array($or)); // array( string "1" )
3. PDO against FreeTDS to SQL Server 2008
$pdo = new PDO('odbc:hpsql3','--','--');
var_dump($pdo->query('SELECT 1')->fetch(PDO::FETCH_ASSOC)); // array (string
"1")
4. PDO against iSeries Access for Linux to AS/400
$pdo = new PDO('odbc:iSeriesDSN','--','--');
var_dump($pdo->query('SELECT 1 FROM
SYSIBM.SYSDUMMY1')->fetch(PDO::FETCH_ASSOC)); // array (string "1")
Expected result:
----------------
I expect to get arrays containing (int) 1
Actual result:
--------------
I actually get arrays containing (string) "1"
