sqlsrv driver for Windows PHP PDO SQL server

Question

I've added and enabled in php.ini given .dll, got Microsoft SQL Server 2012 Native Client, previously configured it successfully on 2 other machines, but on my local one It just says could not find driver have I missed something?

php.ini: extension=php_pdo_sqlsrv_54_ts.dll

script: new PDO("sqlsrv:Server={$_dbConfig['server']};Database={$_dbConfig['dbName']}", $_dbConfig['username'], $_dbConfig['password'])

In php error log I get strange: [08-Nov-2014 18:18:31 UTC] PHP Warning: PHP Startup: in Unknown on line 0 but have no idea why, php.ini itself is configured as my other working machines.

Answer 1

I had to change in php.ini : extension_dir = "ext" to extension_dir = "C:\\PHP\\ext"
