Solution to the problem of extension loading order in PHP

Some PHP extensions are loaded in a sequential order. If you make a mistake, the extension will not be loaded.

1. pdo_sqlsrv is a sqlserver extension. If 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.so.so (/usr/lib64/php/modules/pdo_sqlsrv.so.so: 
undefined symbol: php_pdo_register_driver)) in Unknown on line 0

Copy after login

Solution:

extension=pdo.so
extension=pdo_sqlsrv.so  //放到pdo后面

Copy after login

2. The swoole extension depends on the sockets extension. If loaded before the sockets extension, the following error will be reported:

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

Copy after login

Solution:

extension=sockets.so
extension=swoole.so  //放到pdo后面

Copy after login

Restart php-fpm after loading.
