Docker install ioncube extension (php 5.6)

Dockerfile

RUN curl -o ioncube.tar.gz http://downloads3.ioncube.com/loader_downloads/ioncube_loaders_lin_x86-64.tar.gz \
    && tar -xvvzf ioncube.tar.gz \
    && mv ioncube/ioncube_loader_lin_5.6.so `php-config --extension-dir` \
    && rm -Rf ioncube.tar.gz ioncube \
    && docker-php-ext-enable ioncube_loader_lin_5.6

I get this error:

[09-Nov-2021 12:52:35 UTC] PHP Warning:  Failed loading Zend extension 'ioncube_loader_lin_5.6' (tried: /usr/local/lib/php/extensions/no-debug-non-zts-20190902/ioncube_loader_lin_5.6 (/usr/local/lib/php/extensions/no-debug-non-zts-20190902/ioncube_loader_lin_5.6: cannot open shared object file: No such file or directory), /usr/local/lib/php/extensions/no-debug-non-zts-20190902/ioncube_loader_lin_5.6.so (/usr/local/lib/php/extensions/no-debug-non-zts-20190902/ioncube_loader_lin_5.6.so: undefined symbol: zend_block_interruptions)) in Unknown on line 0

UPDATE: I've fixed it, the issue was that the version of the PHP I was using was higher(7.4) and not compatible with ioncube version 5.6. So I used ioncube version 7.4:

RUN curl -o ioncube.tar.gz http://downloads3.ioncube.com/loader_downloads/ioncube_loaders_lin_x86-64.tar.gz \
    && tar -xvvzf ioncube.tar.gz \
    && mv ioncube/ioncube_loader_lin_7.4.so `php-config --extension-dir` \
    && rm -Rf ioncube.tar.gz ioncube \
    && docker-php-ext-enable ioncube_loader_lin_7.4

and it's now fixed 🥳. Thank you @kubaceg.

tanks it's work

if someone is experiencing the problem with "Failed loading Zend extension" try use script from here https://dev.to/devtronic/ioncube-loader-in-docker-55n1 but do not forget change php version to yours in line LOADER_FILE=$(ls ioncube/*8.3*.so | cat) here

Helped me!
