I am running Xampp v3.

I was only making a simple GetCampaigns. 

This is the error.

Hi, 

Could you confirm the version of the PHP client library that you are using? If you are using an older version of PHP library, could you please try to upgrade to the v32.0.0 version and see if the issue persists? If it does, please log a new issue in the issues tracker. The library owner should be able to assist you with this.

Thanks,

I found the solution, someone in github helped me. Here is our conversation and solution:

https://github.com/googleads/googleads-php-lib/issues/276#issuecomment-349531261

For quick solution, please follow the steps:

This is for PHP 7.1, Xampp 3.2.2, Windows 10 64x/32x.

Steps:

1. download pem file here https://curl.haxx.se//ca/cacert-2017-09-20.pem
2. rename Rename the cacert-2017-09-20.pem file to curl-ca-bundle.crt
3. copy - paste - replace at C:\xampp\apache\bin\
4. open php.ini and find openssl.cafile, uncomment and provide path for curl-ca-bundle.crt
   example: openssl.cafile="C:\xampp\apache\bin\curl-ca-bundle.crt"
5. restart xamp

This is solve! Mine is working now. Thanks!
