ionCube installation :: missing zend

I am in middle of ionCube installation but php configuration is missing zend_extension for ionCube but not specify what is exactly

I am working on CentOs

All well Thanks:)

How do I enable ionCube?

To enable ionCube loader, go to Sites > Tools > ionCube Loader, and press the “Enable” button. At this time, ionCube loader can only be enabled on sites using PHP 7.4 or 8.1 (ionCube is not supported on PHP 8.0).

What is ionCube loader in PHP?

ionCube Loader is a PHP extension that works to decode PHP scripts previously encoded by the ionCube PHP Encoder package. The following information is provided as a guide for installing the ionCube loader needed to run PHP files encoded with ionCube on DreamHost servers.

There were few things I have missed

Select the correct bit release

Match the Loader with your PHP version, e.g. for PHP 5.3, ioncube_loader_lin_5.3.so (extensions are inside the folder)

Add 'zend_extension = /usr/local/ioncube/ioncube_loader_lin_5.3.so' to php.ini

Restart the server
