PHP curl get negotiated TLS version - php

Question

I am trying to check whether my requests are using TLS version >1. While curl command line gives me this information in the verbose output, php does not seem to be.
This is my PHP curl verbose output when the connection is initiated
* About to connect() to *** port 443 (#0)
* Trying 88.*.*.*... * connected
* Connected to *** (88.*.*.*) port 443 (#0)
* CAfile: /etc/pki/tls/certs/ca-bundle.crt
CApath: none
* SSL connection using TLS_RSA_WITH_AES_256_CBC_SHA
* Server certificate:
* subject: ***

* common name: ***
* issuer: CN=Verizon Akamai SureServer CA G14-SHA2,OU=Cybertrust,O=Verizon Enterprise Solutions,L=Amsterdam,C=NL
* Server auth using Basic with user '***'
> GET /my/path HTTP/1.1
Authorization: ***
Host: ***
Accept: */*
< HTTP/1.1 200 OK
< Server: ***

< Connection: keep-alive

* Connection #0 to host *** left intact

How can I say what is the TLS used in a connection? I would like to avoid using any 3rd party options like making request to https://www.howsmyssl.com/a/check
