You must enable the openssl extension to download files via https

Question

PHP CLI SAPI is using different php.ini than CGI or Apache module.

Find line ;extension=php_openssl.dll in wamp/bin/php/php#.#.##/php.ini and uncomment it by removing the semicolon (;) from the beginning of the line.

Verify you are editing the correct php.ini file.

Reference: https://github.com/composer/composer/issues/1440

"WAMP uses different php.ini files in the CLI and for Apache. when you enable php_openssl through the WAMP UI, you enable it for Apache, not for the CLI. You need to modify C:\wamp\bin\php\php-X.Y.Z\php.ini to enable it for the CLI."

make sure you have correct path to extension folder

extension_dir = "ext"

by default it is commented with ; character

I also had the same issue while playing around Zend Framework 2 and composer. I'm using PHP 5.4 (installed via macports) and my solution was to install openssl for PHP 5.4 via macports as well.

sudo port install php54-openssl

I have faced this problem, but configuging openssl (also for cli) did not help.

I have updated composer and this sloved my problem.

Just type:

$ php composer.phar self-update

or

$ composer selfupdate

Good luck!
