http://www.ioncube.com/ For better or worse, ionCube is an encryption method for those that want to protect their code. A pain the neck for system admins, but some want to protect their PHP code, whatever.
Zend Optimizer+ does not play well with ionCube for whatever reason, so it’s really picky on what order they get loaded during startup. It’s important to put the configurations in the correct order, or it will just error out during start up.
You’ll want to grab the loader files from here http://www.ioncube.com/loaders.php
I downloaded and unzipped them to /usr/local/ioncube
Since ionCube is a Zend Extension and not a Zend Module (what’s the difference? I couldn’t tell you, but there is a different) we need to open up the file /usr/local/zend/etc/php.ini and at the very bottom it should look something like this.
; Local Variables: ; tab-width: 4 ; End: [Zend] zend_extension=/usr/local/ioncube/ioncube_loader_lin_5.2.so zend.install_dir=/usr/local/zend zend.conf_dir=/usr/local/zend/etc zend.ini_scandir=conf.d
Of course the important line is the ioncube line, it’s important that it appears before the other lines.
It wasn’t immediately obvious to me, but you need to match your PHP version with the version of ionCube (You can tell I’m using PHP version 5.2).
After it’s done you can restart the web server (if the web server doesn’t start check your log files for clues). Then go to the Zend admin panel to see the PHP INFO page. You should see a section that looks like this….
Did this help you out? It took me a few days to piece together all this information together, I hope this saves you some time (who knows, maybe the future me will be thankful I wrote this down). Let me know your thoughts. email@example.com
