PHP – SSL certificate error: unable to get local issuer certificate

Finally got this to work!

  1. Download the certificate bundle.

  2. Put it somewhere. In my case, that was c:\wamp\ directory (if you are using Wamp 64 bit then it’s c:\wamp64\).

  3. Enable mod_ssl in Apache and php_openssl.dll in php.ini (uncomment them by removing ; at the beginning). But be careful, my problem was that I had two php.ini files and I need to do this in both of them. One is the one you get from your WAMP taskbar icon, and another one is, in my case, in C:\wamp\bin\php\php5.5.12\

  4. Add these lines to your cert in both php.ini files:

  5. Restart Wamp services.
