I have recently gotten a new windows computer and have installed the php symfony framework.
When attempting to use the new command C:> php symfony new blog<
C:> php symfony new blog<
Follow this link, Copy the entire page and save it in a: "cacert.pem"
cacert.pem
Then in your php.ini file insert or edit the following line: curl.cainfo = "[pathtothisfile]\cacert.pem"
php.ini
Or
use composer instead Symfony installer
