Nice, I finally got informix PDO running :3 Both my little script and phpinfo() confirm that Informix PDO was loaded successfully. But, when I try to run another test program that should connect to a database and display a table of data I get this new error: [Fri Sep 27 11:28:30 2013] [error] [client 127.0.0.1] PHP Fatal error: Uncaught exception 'PDOException' with message 'invalid data source name' in /var/www/html/informixTest.php:6\nStack trace:\n#0 /var/www/html/informixTest.php(6): PDO->__construct('informix=148.23...', 'informix', '1nf0rm1x123')\n#1 {main}\n thrown in /var/www/html/informixTest.php on line 6 However, it seems that the cause for this error is that I didn't configured the hosts correctly and I'm currently working on that. Anyhow, I want to thank you again for your advice :3 Next time, I'll pay more attention to what error logs say

@mac_gyver: OK I found something important. I checked the /var/log/httpd/error_log and browsed carefully through today's logs and discovered this error: [Fri Sep 27 09:21:20 2013] [notice] Digest: done PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/pdo_informix.so' - libifcli.so: failed to map segment from shared object: Permission denied in Unknown on line 0 PHP Warning: Module 'PDO' already loaded in Unknown on line 0 PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/pdo_informix.so' - libifcli.so: failed to map segment from shared object: Permission denied in Unknown on line 0 Following the instructions from http://www.whitemiceconsulting.com/2012/02/installing-pdoinformix-on-centos6.html again I realized that SELinux wouldn't allow me to load certain modules, so I ran this command: chcon -t lib_t /opt/IBM/informix/lib/cli/libifcli.so and then restarted apache. Checking the error log after that, I found that a similar error emerged, but this time with a different module, so I'll just keep running that command for each module that fails to load. I'll let you know if, after clearing all these errors, I can finally get informix up and running. Thanks for your advice.

Thanks for your reply. I checked the phpinfo() page again, as you suggested, and it says it is loading from /etc/php.ini, which has the lines 'extension=pdo.so' and 'extension=pdo_informix.so' around line 937 (in the 'Dynamic Extensions' section).

Good day everybody, I am in desperate need for help trying to sort this out. At work I was asked to install PHP and Informix on a CentOS 6 machine so they can begin developing some web projects. I've been working on it for almost a week now, but I still can't get the PDO working. I followed 3 guides already, two of which are the following: http://www.whitemiceconsulting.com/2012/02/installing-pdoinformix-on-centos6.html http://lemachete.wordpress.com/2009/06/26/instalar-pdo_informix-en-linux-centos/ [in spanish] and the third one was written by a person that used to work with us and was provided by a co-worker so I can't post it here (company's property). I followed each guide to the letter, and even combined the guides trying to get informix running, but to no avail. I already formatted the machine 3 times so I can start over. So far, this is what I managed to do: The environment variable INFORMIXDIR is set to /opt/IBM/informix (the same directory where I installed informix) Both the pdo.so and pdo_informix.so were created in /usr/lib/php/modules The following lines were added in /etc/php.ini: extension=pdo.so and extension=pdo_informix.so I have a user called informix Just in case, I also added the following line to the pdo.ini file in /etc/php.d: extension=pdo_informix.so I also modified some other files like the /etc/init.d/httpd and the /etc/profile but as far as I know, just doing the above should be enough to get the Informix PDO up and running. However, if I try to run this program: <?php echo '<h3>Available PDOs:</h3>'; foreach (PDO::getAvailableDrivers() as $driver) { echo $driver . '<br/>'; } ?> All I get as a result is: Available PDOs: sqlite Checking the phpinfo() confirms that only the SQLite PDO is loaded. Also if I try to access the server using $db = new PDO(); sentence, I get this error: [Thu Sep 26 11:36:21 2013] [error] [client 127.0.0.1] PHP Fatal error: Uncaught exception 'PDOException' with message 'invalid data source name' in /var/www/html/informixTest.php:22\nStack trace:\n#0 /var/www/html/informixTest.php(22): PDO->__construct('informix=148.23...', 'informix', '1nf0rm1x123')\n#1 {main}\n thrown in /var/www/html/informixTest.php on line 22 I already tried everything I've found on the web, but nothing works. Can somebody please help me sort this out? What am I doing wrong? PS: just in case anybody wonders, I did restart apache after applying any modification to the PHP configuration. I also checked if there is another php.ini file that is overriding the one I modified, but there is none.
