PHP 5.5.8 and PDO Informix 1.3.1 Installation Issue

Hi I'm trying to get PDO Informix working on a new system with PHP 5.5.8 and I can't seem to get PHP to recognize the driver. Here are my system Specs: Red Hat Enterprise Linux Server release 6.2 (Santiago) PHP 5.5.8 (cli) (built: Feb 5 2014 20:12:40) Copyright (c) 1997-2013 The PHP Group Zend Engine v2.5.0, Copyright (c) 1998-2013 Zend Technologies PDO_INFORMIX-1.3.1 Informix SDK IBM Informix Client SDK and IBM Informix Connect 3.50.xC9, August 2011 Apache Server version: Apache/2.4.7 (Unix) Server built: Feb 5 2014 11:07:53 Server's Module Magic Number: 20120211:27 Server loaded: APR 1.5.0, APR-UTIL 1.5.3 Compiled using: APR 1.5.0, APR-UTIL 1.5.3 I'm able to connect to my Informix server with PERL, so I'm confident the SDK is working properly. I've tried both methods of getting PHP to recognize the Informix driver. Method 1: Install PHP without the flag with-pdo_informix ie. Configure, make, make install Install PDO Informix ie. Configure -with-pdo-informix=/sdkdir, make, make install Method 2: Install PHP with flag with-pdo_informix ext_skel -extname=pdo_informix buildconf configure make install I've added the file /etc/php.d/pdo_informix.ini I've updated /etc/sysconfig/httpd phpinfo has all the correct env variables set for Informix. It also shows the pdo_informix section, but there is no line of data below it and the PDO drivers only shows sqlite. The error_log file does not show any errors. Any suggestions on how to get PHP to recognize the driver would be greatly appreciated. Joel A. Lamb  joel.lamb@ftr.com
