@DivineOmega, the Travis CI build work is failed.

It looks like the php-7.0 test is failed because the cURL handshake is failed.

The Exception message is as follows:

GuzzleHttp\Exception\ConnectException: cURL error 35: gnutls_handshake() failed: Handshake failed.

Do you have any idea about this solution?

It looks like it's the certificate issue after reading this issue and this issue you've commented.

Perhaps we can update the certificate before running phpunit in Travis CI build.

@peter279k This is actually a bug with Travis not being able to perform PHP Curl requests to HTTPS URLs in PHP 7.0.

See here for more information: travis-ci/travis-ci#6339

This was why PHP 7.0 is not in the .travis.yml file.

Feel free to just remove PHP 7.0 from your .travis.yml.

@DivineOmega, thank you for your reply.

You mean we just skip the php-7.0 test in Travis CI build?

How can we ensure the php-7.0 can be worked well? Perhaps this package will add php: "^7.1" for require block in composer.json.

@peter279k I think we might have to just skip PHP 7.0. I don't want to increase the minimum version the package supports, as I know many web applications are still (unfortunately) using PHP 5.6.

I would suggest just skipping PHP 7.0 for now to get this merged.

[peter279k]

@DivineOmega, just notice you I've removed php-7.0 test in .travis.yml and let this package require php-7.1 version at least. It defines in composer.json.

Thanks!
