Downloaded Microsoft Drivers for PHP for SQL Server Put:

php_pdo_sqlsrv_7_ts_x86.dll and php_sqlsrv_7_ts_x86.dll into \php-7.2.1-nts \ext

And in php.ini

extension=php_sqlsrv_72_ts_x86.dll

extension=php_pdo_sqlsrv_72_ts_x86.dll

Restarted Apache

I still get an error. Please give me some advice.
