I am trying to get the version of tls which is currently used when invoking the url. I'm trying to get the tls version from php curl like the command curl in Ubuntu.

for example:

curl -v https://qpyl.uas-gw.info
* Rebuilt URL to: https://qpyl.uas-gw.info/
*   Trying 54.199.158.6...
* Connected to qpyl.uas-gw.info (54.199.158.6) port 443 (#0)
* found 1 certificates in ca.crt
* found 692 certificates in /etc/ssl/certs
* ALPN, offering http/1.1
* SSL connection using TLS1.2 / ECDHE_RSA_AES_256_GCM_SHA384

like this to show the tls version result.

But I cannot get the version in php curl like the above curl does

SSL connection using TLS1.2 / ECDHE_RSA_AES_256_GCM_SHA384

php openssl version: openssl/1.0.2g

php version: 5.5.38.

have a look at this, might be helpful https://stackoverflow.com/questions/27904854/verify-if-curl-is-using-tls – RashFlash Sep 22 '17 at 05:55
I already tried with this but cannot get the tls version. please , do you have another. Thanks – Harris Dingtai Sep 22 '17 at 05:58
well it does gives me this " TLS 1.2 " when i follow the above example. – RashFlash Sep 22 '17 at 05:59
Can it echo out the version result without reading the documents the link that indicated? – Harris Dingtai Sep 22 '17 at 06:00
No, it doesn't. you need to send curl request to that url and read the response , screenshot => https://www.screencast.com/t/BCvvZc9Inq0 – RashFlash Sep 22 '17 at 06:02
please be here bro, I don't understand that url https://www.howsmyssl.com/a/check. because I get the result I think it is written by default. – Harris Dingtai Sep 22 '17 at 06:07
ok, you said above " I am trying to get the version of tls which is currently used when invoking the url " . Now you can use " https://www.howsmyssl.com/ " to check what SSL client you using. – RashFlash Sep 22 '17 at 06:09
I just can check only with this url right? – Harris Dingtai Sep 22 '17 at 06:11
yes . this will tell you TLS version – RashFlash Sep 22 '17 at 06:13
Thanks @ RashFlash. – Harris Dingtai Sep 22 '17 at 06:18
@HarrisDingtai, it sounds like you have the same problem as me. You want to be able to test various urls to see if THEY support TLS.... not check if your request is using TLS version X. I made a new question for that here: https://stackoverflow.com/questions/49186863/php-how-to-see-if-a-server-supports-tls-1-0 – rockstardev Mar 09 '18 at 05:21
Thanks you @coderama – Harris Dingtai Mar 10 '18 at 01:29
