pdo_psql未在MAMP 4.0.1中加载

Question

A few hours ago I installed MAMP Pro 4.0.1 on Windows 10 so far everything was fine until I decided to uncomment pdo_psql.dll inside php.ini to create a connection from PHP to Postgresql but something went wrong, The driver doesn't load it says:

Warning: PHP Startup: Unable to load dynamic library 
'C:\php\ext\php_pdo_pgsql.dll' - The  module can't be found.

Answer 1

I found the issue. the thing was that the extention dir wasn't uncommented by default settings so I had to uncomment it in php.ini file.

extension_dir = "ext"
