How to Resolve \"OpenSSL Extension Missing\" Warning for Composer in WAMP

Composer Warning: OpenSSL Extension Missing in WAMP

When installing Composer on WAMPServer, many users encounter the warning "openssl extension is missing." Despite enabling the extension through the WAMP UI, the issue persists. This article will provide a solution to this problem.

WAMP utilizes distinct php.ini files for Apache and the CLI. When you enable the php_openssl extension through WAMP's interface, you only enable it for Apache, not the CLI.

Solution:

To rectify this issue, follow these steps:

1. Navigate to the directory C:wampbinphpphp-5.4.3.
2. Open the file php.ini.
3. Search for the line: extension=php_openssl.dll
4. Verify that this line is uncommented (not preceded by a ;).
5. Save the changes and restart WAMPServer.

By modifying php.ini in the CLI directory, you have enabled the OpenSSL extension for the CLI. This will alleviate the "openssl extension is missing" warning when using Composer.
