I have downloaded PHP 7 and connected it to Apache web server and it works fine, but I cannot activate the mysqli extension what I did was: In the php.ini file, I removed the semicolon from extension=php_mysqli.dll , I have seen that the dll file exists in the folder C:\php\ext\ so I also added extension_dir = C:\php\ext .
However when I navigate to the phpinfo(); page on apache server , nothing has changed and there is no mysqli, only mysqlnd. Any ideas on how to fix this?
