Missing PHP registered Streams: https and ftps

[net-solution]

Hello Guy's,
we have a problem. Our customer is running an Internet Shop with osCommerce. We have installed for him an Contribution for making Credit Card payments. But when the connection to the credit card company must establish the page shows us an error:

Notice: file() [function.file]: Unable to find the wrapper "https" - did you forget to enable it when you configured PHP? in C:\Inetpub\vhosts\xxxxxx.eu\httpdocs\test_file2.php on line 10

Warning: file(https://www.saferpay.com/hosting/CreatePayInit.asp) [function.file]: failed to open stream: Invalid argument in C:\Inetpub\vhosts\xxxxxx.eu\httpdocs\test_file2.php on line 10

Our php-info file shows us this:

Registered PHP Streams php, http, ftp, compress.zlib

We think thats the fault. How can we get "https" and "ftps" into "Registered PHP Streams"?

We hope for your help.
Thanks in advance.
