How to run a module in PHP?

Question

PHP

Good afternoon! I have a module for PHP, during the test it displays an error:

РHP Warning:  PHP Startup: Unable to load dynamic library 'kalkancrypt.so' (tried: /usr/lib64/php/modules/kalkancrypt.so (/usr/lib64/php/modules/kalkancrypt.so: undefined symbol: SetProxy), /usr/lib64/php/modules/kalkancrypt.so.so (/usr/lib64/php/modules/<b>kalkancrypt.so.so</b>: cannot open shared object file: No such file or directory)) in Unknown on line 0

For some reason, the .so extension was displayed twice in the error
. The imagemagik module also worked fine before that. After installing PHP 7,3,9 and he started to swear:

PHP Warning:  PHP Startup: Unable to load dynamic library 'imagick.so' (tried: /usr/lib64/php/modules/imagick.so (/usr/lib64/php/modules/imagick.so: undefined symbol: spl_ce_Countable), /usr/lib64/php/modules/<b>imagick.so.so</b> (/usr/lib64/php/modules/<b>imagick.so.so</b>: cannot open shared object file: No such file or directory)) in Unknown on line 0
Could not open input file: test.php

Accordingly, the error in the script:

Fatal error: Uncaught Error: Call to undefined function KalkanCrypt_Init() in
