Hello there,
Can you not leave php hanging and not even give it a basic cert authority? https://curl.se/ca/cacert.pem
The main php.ini should have openssl.capath = /path/to/cacert.pem
or otherwise /etc/ssl/cert.pem
on macOS.
Currently using 5.10.3 and can’t get php to curl anything without screaming about being unable to get crypto going.
