I got the error
I’ve installed sql drivers following the instructions here: https://github.com/Microsoft/msphpsql
I restarted both apache2 and php-fpm (whatever It is, I didn’t know before today)
From a web page, I checked phpinfo() and I see "sqlsrv" within installed extensions.
I cannot see any problem, but Yii cannot find the driver.
My connection is configured as is:
"mexal_db" => array ( 'class' => "CDbConnection", 'connectionString' => 'dblib:host=SRV-MEXAL;dbname=at6_rp', 'enableParamLogging' => false, 'username' => '<hidden>', 'password' => '<hidden>', 'charset' => 'utf8', ),
I’ve another machine, an old Ubuntu 8 with PHP 5.2, and this works, so the connection string is ok. I think.
