How to enable PHP’s openssl extension to install Composer?

by

It is possible that WAMP and Composer are using different PHP installations. Composer will use the PHP set in the PATH environment variable.

If you want to enable the openssl extension to install Composer, first you need to check the location of the PHP installation.

  1. Open a Command Prompt, type: echo %PATH% then check for the location of your PHP installation.
  2. Go to that location and edit the file named: php.ini.
  3. Uncomment the line extension=php_openssl.dll by removing the semicolon at the beginning.

Now you are good to install Composer.
