Ioncube loader I have installed on my server in the directory / usr / local / IonCube is the ioncube_loader_lin_5.4.so file and this set in php.ini, but I want to encrypt a .php file and have no idea how to use it I saw an example of encoded file and began: "if (extension_loaded ('ionCube Loader')!"
The ionCube Loader can only load encoded files. To actually produce ionCube encoded files you'll have to purchase the ionCube PHP Encoder (see here).
In addition, you can download the trial of the ionCube PHP Encoder here.
If you have any specific questions regarding the ionCube PHP Encoder, you can contact ionCube's sales team, either by writing an email, via live chat or by opening a ticket at the ionCube support HelpDesk.
