I tried to install PHP-mbstring and PHP-Intl but it still not works.

I am running in PHP 7.0 with debian 9. I don't know what to do now.

thanks for answering ! (sorry for my bad English ^^)

Answer 1

Go to your ../php/php.ini file and check if all those .dll files shown as warning are enabled or not. If not enabled, then enable them. If issue still persists, then check your ../php/ext folder to see if you have those .dll files present there. Or else you have to manually download and paste them in that folder.
