I am on windows. Can alone help me please? I am still a beginner in these stuffs Thanks in advance
You need to enable the open_ssl extension on your PHP.ini
Open your PHP.ini , search for this line
;extension=php_openssl.dll
Remove the ; before the line , save the file and restart your webserver and you are good to go.
Create a simple test file like test.php, add <?php phpinfo(); and execute it. Search for Loaded Configuration File line and see the path next to that line.
In order to use OpenSSL function you need to install the OpenSSL extension for php. Documentation
