please help if anyone knows the issue or solution of this.

Thanks in advance

@Uli Lehmann – I had the same problem when trying to run php version 7.2.10. I believe that the current microsoft drivers only support version 7.0.

Configure wampserver to use PHP 7.0.32

Download and install SQLSRV40 to this location:
C:\wamp64\bin\php\php7.0.32\ext

add the following lines to the php.ini

extension=php_sqlsrv_7_ts_x64.dll
extension=php_pdo_sqlsrv_7_ts_x64.dll

Restart apache (or all services which is easier)

I am a Little lost here:
in my Setup the Drivers do not load and in phphinfo I do not find “pdo_sqlsrv” :(.

here my Setup:
Drivers are in Directory:
c:\wamp64\php\php7.2.10\ext

php.ini:
extension=php_sqlsrv_7_ts_x64.dll
extension=php_pdo_sqlsrv_7_ts_x64.dll

done the restart but nothing works – can anybody help me.

Thank you.
