For some php extensions, the loading sequence is in order. If you make a mistake, the extension will not be loaded.
1. pdo_sqlsrv is a sqlserver extension. If it is loaded before the pdo extension, the following error will be reported.
PHP Warning: PHP Startup: Unable to load dynamic library 'pdo_sqlsrv.so' (tried: /usr/lib64/php/modules/pdo_sqlsrv.so (/usr/lib64/php/modules/pdo_sqlsrv.so: cannot open shared object file: No such file or directory), /usr/lib64/php/modules/pdo_sqlsrv. (/usr/lib64/php/modules/pdo_sqlsrv.: undefined symbol: php_pdo_register_driver)) in Unknown on line 0
Solution:
extension= extension=pdo_sqlsrv.so //Put it inpdolater
2. Swoole extension depends on sockets extension. If the sockets extension is loaded before sockets extension, the following error will be reported.
PHP Warning: PHP Startup: Unable to load dynamic library '' (tried: /usr/lib64/php/modules/ (/usr/lib64/php/modules/: cannot open shared object file: No such file or directory), /usr/lib64/php/modules/ (/usr/lib64/php/modules/: undefined symbol: php_sockets_le_socket)) in Unknown on line 0
Solution:
extension= extension= //Put it inpdolater
After loading, restart and php-fpm is fine
