php - Call to undefined function curl_init() even it is enabled in php7

Question

I've just installed php7 to my Ubuntu. At first, there was no problem, my web site was working. But suddenly, it started to return Call to undefined function curl_init() error. Now, my pages contain curl codes do not work.

In phpinfo(), it looks Curl is enabled. There were similar questions but none of them handled it in php7. I thought it should be something different than others.

Edit: When I try

php -i | grep curl       

in terminal, it returns

/etc/php/7.0/cli/conf.d/20-curl.ini,
curl

Answer 1

I've had similar problem with curl after upgrade to XX (16.04). After reinstalling curl with:

sudo apt-get install php-curl

And server restart

sudo service apache2 restart

everything went back to normal :)
