Enabling the OpenSSL in XAMPP
Yes, you must open php.ini and remove the semicolon to:
;extension=php_openssl.dll
If you don't have that line, check that you have the file (In my PC is on D:\xampp\php\ext) and add this to php.ini in the "Dynamic Extensions" section:
extension=php_openssl.dll
[PHP_OPENSSL]
extension=php_openssl.dll
This is the answer.
