All of the answers are correct ; but the most important thing is You have to find the right php.ini file. check this command in cmd " php --ini " is not the right answer for finding the right php.ini file.
if you edit

*I recommend you to search *.ini in wamp/bin or xxamp/bin or any server you use and change them one by one and check it. *
