Why PHP CLI says php_pdo.dll cannot be found ?

Question

I have added php extensions directory (which contains php_pdo.dll, ...) to path environment variables, still when launching php.exe on command line, it complains it cannot find this dll and others.

What's wrong ?

Thanks.

Answer 1

Look for "extension_dir" directive from phpinfo() output and save your proper extension DLL to that directory.

You can change extension directory from extension_dir directive in php.ini.

Answer 2

Do you install it during the PHP installation?

Here's how you can do it on Windows, make sure you enable the appropriate extension.
