CodeIgniter Call to undefined function odbc_connect

Question

I am running Codeigniter 1.7 on Xampp 3.2 and on the index page I have:

Call to undefined function odbc_connect

Pdo is enabled (php.info):

ODBC Connection Pooling Enabled, strict matching

I have then installed odbc drivers and enabled in php.ini:

extension=php_sqlsrv_7_ts_x64.dll
extension=php_pdo_sqlsrv_7_ts_x64.dll

not sure about this last step, I have also same name modules but called 'nts'.

Answer 1

I found the solution, missing in php.ini:

extension=php_odbc.dll
