Step 1 — Choosing the Right ionCube Version
It is important that the version of ionCube you choose matches your PHP version, so first, you need to know:
- The version of PHP our web server is running, and
- If it is 32-bit or 64-bit.
If you have a 64-bit Ubuntu server, you are probably running 64-bit PHP, but let’s make sure. To do so, we’ll use a small PHP script to retrieve information about our server’s current PHP configuration.
Create a file called
info.php file in the root directory of your web server (likely
/var/www/html , unless you’ve changed it) using
nano or your favorite text editor.
sudo nano /var/www/html/info.php
Paste the following inside the file, then save and close it.
After saving the changes to the file, visit
http://your_server_ip/info.php in your favorite browser. The web page you’ve opened should look something like this:
From that page, look at the header at the top where it says PHP Version . In this case, we’re running 7.0.8. Then, look at the System line. If it ends with x86_64 , you’re running 64-bit PHP; if it ends with i686 , it’s 32-bit.
With this information, you can proceed with the download and installation.
Step 2 — Setting Up ionCube
Next, extract the archive.
tar xvfz ioncube_loaders_lin_x86-64.tar.gz
This creates a directory named
ioncube which contains various files for various PHP versions. Choose the right folder for your PHP version. In our example, we need the file PHP version
7.0 , which is
ioncube_loader_lin_7.0.so . We will copy this file to the PHP extensions folder.
To find out the path of the extensions folder, check the
http://your_server_ip/info.php page again and search for extension_dir .
In this example, it’s
/usr/lib/php/20151012 , so copy the file there:
sudo cp ioncube/ioncube_loader_lin_7.0.so /usr/lib/php/20151012/
For PHP to load the extension, we need to add it to the PHP configuration. We can do it in the main
php.ini PHP configuration file, but it’s cleaner to create a separate file. We can set this separate file to load before other extensions to avoid possible conflicts.
To find out where we should create the custom configuration file, look at
http://your_server_ip/info.php again and search for Scan this dir for additional .ini files .
So, we’ll create a file named
00-ioncube.ini inside the
/etc/php/7.0/apache2/conf.d directory. The
00 at the beginning of the filename ensures this file will be loaded before other PHP configuration files.
sudo nano /etc/php/7.0/apache2/conf.d/00-ioncube.ini
Paste the following loading directive, then save and close the file.
zend_extension = "/usr/lib/php/20151012/ioncube_loader_lin_7.0.so"
For the above change to take effect, we will need to restart the web server.
If you are using Apache, run:
sudo systemctl restart apache2.service
If you are using Nginx, run:
sudo systemctl restart nginx
You may also need to restart
php-fpm , if you’re using it.
sudo systemctl restart php7.0-fpm.service
Finally, let’s make sure that the PHP extension is installed and enabled.
Step 3 — Verifying the ionCube Installation
Back on the
http://your_server_ip/info.php page, refresh the page and search for the “ionCube” keyword. You should now see with the ionCube PHP Loader (enabled) :
That confirms that the PHP ionCube extension is loaded on your server.
It can be a bit of a security risk to keep the
info.php script, as it allows potential attackers to see information about your server, so remove it now.
sudo rm /var/www/html/info.php
You can also safely remove the extra downloaded ionCube files which are no longer necessary.
sudo rm ioncube_loaders_lin_x86-64.tar.gz sudo rm -rf ioncube_loaders_lin_x86-64
ionCube is now fully set up and functional.
