Errors in installing php composer on windows

Question

While installing the composer to user the laravel framework, I got some errors :

Download failed: file_get_contents(): SSL operation failed with code 1. OpenSSL          


        

Answer 1

Having the OpenSSL extension enabled does not mean it is configured correctly.

It fails to validate the certificate for getcomposer.org. That means either some man-in-the-middle server messes with your request or you somehow did not configure the set of default CA Authorities. Your server operator can tell you more.
