PHP Warning: PHP Startup: Unable to load dynamic library 'pdo_sqlsrv' (tried: /usr/lib64/php/modules/pdo_sqlsrv (/usr/lib64/php/modules/pdo_sqlsrv: cannot open shared object file: No such file or directory), /usr/lib64/php/modules/pdo_sqlsrv.so (/usr/lib64/php/modules/pdo_sqlsrv.so: undefined symbol: php_pdo_register_driver)) in Unknown on line 0
PHP 8.1.29 (cli) (built: Jun 5 2024 05:51:57) (NTS gcc x86_64)
以上错误需要修改php.ini 将extension=pdo 放在 extension=pdo_sqlsrv 上面，如果上面没有就加上。
