PHP Warning: PHP Startup: Unable to load dynamic library 'zip.so' (tried: /usr/lib64/php/modules/zip.so (/usr/lib64/php/modules/zip.so: undefined symbol: zip_register_cancel_callback_with_state), /usr/lib64/php/modules/zip.so.so (/usr/lib64/php/modules/zip.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0
PHP Unable to load dynamic library zip.so after upgrade.
Resolution
Firstly, check there are no php-package conflicts. Remove/uninstall existing php-packages from system & then reinstall the latest PHP version from RHEL repositories.
With command $ rpm -qa | grep php one can check existing php packages.
The library zip.so is not loaded because of missing libzip dependency of module php-pecl-zip.

Remove 2 Packages
Solution 2- If one is able to see zip module after running command # php -m and still getting Unable to load dynamic library 'zip.so' error follow below steps:
If output looks something like above, remove libzip.so.5 => /usr/local/lib/libzip.so.5 (0x00007fad7a5e0000) & rebuild it, as module libzip.so.5 is getting loaded from a different location.
It should look like libzip.so.5 => /lib64/libzip.so.5 (0x00007fad7a5e0000)
