php:8.2-fpm Docker镜像中IonCube Loader加载失败如何解决？

问题背景 #

我准备购买Setasign的FPDI-Parser完整版许可，先试用套件，但加载试用版专属工具时页面报错：

Script error: the Ioncube Loader for PHP needs to be installed. The ionCube Loader is the industry standard PHP extension for running protected PHP code, and can usually be added easily to a PHP installation. For Loaders please visit get-loader.ioncube.com and for an instructional video please see http://ioncu.be/LV

尝试的安装步骤 #

我使用php:8.2-fpm Docker镜像，在Dockerfile中添加以下命令安装ionCube Loader：

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_8.2.so `php-config --extension-dir` \
    && rm -Rf ioncube.tar.gz ioncube \
    && docker-php-ext-enable ioncube_loader_lin_8.2

错误现象 #

执行docker-compose --build up后，运行php -v输出：

Warning: Failed loading Zend extension 'ioncube_loader_lin_8.2' (tried: /usr/local/lib/php/extensions/no-debug-non-zts-20220829/ioncube_loader_lin_8.2 (/usr/local/lib/php/extensions/no-debug-non-zts-20220829/ioncube_loader_lin_8.2: cannot open shared object file: No such file or directory), /usr/local/lib/php/extensions/no-debug-non-zts-20220829/ioncube_loader_lin_8.2.so (/usr/local/lib/php/extensions/no-debug-non-zts-20220829/ioncube_loader_lin_8.2.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

文件检查结果 #

文件实际存在，执行ls -la /usr/local/lib/php/extensions/no-debug-non-zts-20220829/ioncube_loader_lin_8.2.so结果：

-rw-rw-r-- 1 507 507 1761720 Jul  2 09:29 /usr/local/lib/php/extensions/no-debug-non-zts-20220829/ioncube_loader_lin_8.2.so

执行file /usr/local/lib/php/extensions/no-debug-non-zts-20220829/ioncube_loader_lin_8.2.so结果：

/usr/local/lib/php/extensions/no-debug-non-zts-20220829/ioncube_loader_lin_8.2.so: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, stripped

执行ldd /usr/local/lib/php/extensions/no-debug-non-zts-20220829/ioncube_loader_lin_8.2.so结果：

not a dynamic executable

我搞不懂为什么文件存在却加载失败，求解决思路，需要更多信息请告知。
