Hi,
I can see that it is possible to use php_pdo_ibm.dlll.
i check the documentation, but this driver doesnt work on PHP 5.5.25
https://pecl.php.net/package/PDO_IBM/1.3.3/windows.
i didnt find any other PDO for 64Bits windows and php 5.5.
This is the reason the service were not connecting to the AS400 Db2,
I I guess i will need to downgrade php to 5.4 to make it work, but i guess this will affect to DF.
