How to Resolve Composer Error: \'The openssl extension is missing\'?

Composer Warning: Missing openssl Extension in Win7/64 WampServer 2.2

If you encounter the message "The openssl extension is missing, which will reduce the security and stability of Composer" while installing Composer, it indicates that the openssl extension for PHP is not enabled.

Troubleshooting Steps:

1. Check WampServer Extension Settings

• Open the WampServer menu from the system tray.
• Click "PHP" > "PHP Extensions" and check if "php_openssl" is enabled (marked with a checkmark).

2. Verify PHP.ini

• Open the WampServer php.ini file located at "C:wampbinapacheapache2.4.3binphp.ini".
• Search for "openssl" and ensure that it is not commented out (without a semicolon at the beginning of the line).

3. Check CLI PHP.ini

• Composer installs via the command-line interface (CLI), which uses a different php.ini file than Apache.
• Open the CLI php.ini file located at "C:wampbinphpphp-5.4.3php.ini".
• Ensure that "extension=php_openssl.dll" is not commented out.

4. Restart WampServer

• Restart WampServer for the changes to take effect.

5. Test HTTPS

• Try browsing to one of your local sites using HTTPS to ensure that openssl is working correctly.

Additional Tip:

If the issue persists, consider recompiling PHP with the "--with-openssl" flag to explicitly enable the openssl extension.
