Why Am I Getting 'Unable to Find the HTTPS Wrapper' Error in PHP?

Unable to Find the HTTPS Wrapper - Resolving the Issue

Background:
This error message typically arises when attempting to access resources over HTTPS using PHP's file_get_contents() function. The underlying cause is the absence of the necessary HTTPS wrapper, which must be enabled in PHP's configuration.

Troubleshooting Steps:

1. Verify Extension Loading:

• Ensure that the openssl extension is loaded in your PHP configuration. Check the php.ini file for the line:

  extension=php_openssl.dll

  Copy after login
• Uncomment this line if it is preceded by a semicolon (;).
• Restart your web server (e.g., Apache) for the changes to take effect.

2. Cross-Platform Considerations:

• If running on a Windows system, ensure that OpenSSL is installed and the library files (libeay32.dll and ssleay32.dll) are present and properly configured.

3. HTTPS Wrapper Activation:

• In the PHP configuration, ensure that the "allow_url_fopen" setting is enabled:

  allow_url_fopen=On

  Copy after login

• Check that the "enable_curl" setting is also enabled (if using cURL):

  enable_curl=On

  Copy after login

4. Enable OpenSSL in Phar Extension:

• If the Phar extension is disabled, enable it in the PHP configuration by removing the semicolon before:

  extension=phar.dll

  Copy after login

5. Check Wrapped Extensions Load Order (Optional):

• Edit php.ini and add the following line to the bottom:

  zend_extension_ts="C:\path\to\php_openssl.dll"

  Copy after login
• Ensure that the OpenSSL extension is listed before the curl extension (if used).

Additional Notes:

• As mentioned in the problem details, phpinfo() may not always show the correct loaded php.ini file.
• If the issue persists, consider consulting the documentation for your specific operating system and web server configuration.

Resolution:

By implementing these steps, you can successfully enable the HTTPS wrapper in PHP and resolve the "Unable to find the wrapper 'https'" error when accessing resources over HTTPS using file_get_contents().
