PDO_IBM

Interface for PHP to DB2 for z/OS, DB2 for LUW, DB2 for i.

Pre-requisites

The minimum PHP version supported by driver is PHP 7.3 and the latest version supported is PHP 8.2.

IBM i users

When running on IBM i, PDO_IBM doesn't link with the Db2 LUW client library, but instead with libdb400, which provides a PASE wrapper for SQL/CLI. The differences between SQL/CLI in IBM i and the LUW driver are wrapped for you. You don't need Db2 Connect on IBM i as a result.

To install, make sure you have the new Yum-based OSS environment. Install PHP, plus any dependencies like so:

yum install sqlcli-devel gcc make-gnu

Tony Cairns' replacement libdb400 is not yet tested, but may be desirable due to its greater debugging features.

IBM i users should read tests/README400.txt in order to set up prequisites for unit tests.

LUW/z/Db2 Connect users

CLIDRIVER should be installed in your system. If not installed Download from the below link.

DOWNLOAD CLI DRIVER

PHP should be installed in your system.

How to install php pdo_ibm extension in Linux/Mac

If IBM_DB_HOME and LD_LIBRARY_PATH environment variables are not set, then set them with installed CLIDRIVER. (say CLIDRIVER installed at /home/user/clidriver)

export IBM_DB_HOME=/home/user/clidriver 
export LD_LIBRARY_PATH="${IBM_DB_HOME}/lib"

Install this extension:
```
pecl install pdo_ibm
```
Open the php.ini file in an editor of your choice. Edit the extension entry in the php.ini file in the <local_php_directory>/php/lib directory to reference the PHP driver:
```
extension=pdo_ibm.so
```
Ensure that the PHP driver can access the libdb2.so CLI driver file by setting the LD_LIBRARY_PATH variable for Linux and UNIX operating systems other than the AIX® operating system. For AIX operating system, you must set LIBPATH variable.
Optionally, if the PHP application that is connecting to an IBM database server is running in the HTTP server environment, add the LD_LIBRARY_PATH variable in the httpd.conf file.

Prebuilt binaries for Windows

Add the CLIDRIVER\bin path to the PATH environment variable like so (for a batch file):
```
set PATH=<CLIDRIVER installed path>\bin;%PATH%
```
Download the DLLs for PHP 7.x and 8.x from the ibmdb repository. Select the build for the PHP that matches the version, architecture, and thread model.
Open the php.ini file in an editor of your choice. Edit the extension entry in the php.ini file in the <local_php_directory>\php\lib directory to reference the driver:
```
extension=php_pdo_ibm
```

How to run sample program

Create a connect.php script with the following content:

<?php

$dsn = 'ibm:<DSN NAME>';
$user = '<USER>';
$pass = '<PASSWORD>';

$pdo = new \PDO($dsn, $user, $pass);

To run the sample:

php connect.php
