What kind of error...?

What OS and webserver is the remote site running?

What OS, PHP version and webserver is your local site running?

The script is running under http://, so that is probably the problem
since http can't send to https (right?).

No..! HTTP/HTTPS is a question of unencrypted or encrypted communication
between PHP running the script with the file() function and the remote
site. How you invoked the script is not an issue.

Thx, for any suggestions.

Ditto, for anything resembling a clue of what you're experiencing... ;-)

What error?

According to

HTTP and HTTPS

PHP: http:// - Manual

http://www.php.net/manual/en/wrappers.http.php

Accessing HTTP(s) URLs

PHP needs OpenSSL support compiled-in to access HTTPS resources.

I have no clue.

I have a xampp test enviroment (Apache w/ PHP 4.4.4).
I'm sorry, but when I uploaded the script to my webhoster it worked.
So it might be an issue with the OpenSSL support as Micha suggested.
I just looked at the phpinfo() pages of both configs and on both
systems is openSSL enabled. My hoster has an older version, though.
But that shouldn't be the problem.

The error I get from my localhost is the following:
Warning: file(https://SITE) [function.file]: failed to open stream:
Invalid argument in ... on line...
It works fine with normal HTTP.

Since, the script is running on my webspaces I'm fine. But I still
would really like to know why it isn't working from localhost.

1. Check your firewall.
2. Check your internet connection wether use proxy or not to access
internet.

Buggy IIS and line endings from a MAC are easy to overcome, but obviously
not what's giving you problems. Never mind the question.

I have a xampp test enviroment (Apache w/ PHP 4.4.4). I'm sorry, but

Micha said it all...

PHP :: Bug #28234 :: HTTPS wrapper doesn't work

http://bugs.php.net/bug.php?id=28234

PHP :: Bug #38798 :: OpenSSL init corrected in php5 but not in php4

http://bugs.php.net/bug.php?id=38798

<guesswork>
I think the SSL entry you are looking for is an "ssl" entry under
"Registered Stream Socket Transports" in the phpinfo() page. And probably
an "https" entry under "Registered PHP Streams".
</guesswork>

The error I get from my localhost is the following: Warning:
file(https://SITE) [function.file]: failed to open stream: Invalid
argument in ... on line...

Your PHP installation is probably broken from the maintainer. Try an
upgrade, your distro's own PHP package or build PHP yourself, using bits
and bytes... ;-)

HOW-TO: avoid coding problems and find errors

This all below is my opinion, not any official post though...

1) have a debugging/error handling system. It is not so difficult to make, I
have made one myself and it really often helped us in development.

2) test code ALL the time, after every couple of lines, not in big chunks.

3) leave debugging features inside, even if you use simple lines like:
echo "now variable i = $i";
comment it, when you don't need it, but keep it there!

4) name varables in a way that even others understand them
$person['phone'] is good name , $p['p'] is bad.

5) put useful comments here and there. don't think commenting is waste of
time. avoid excessive egoboost comments, though.

What has this got to do with the original subject?

6) Libraries and most used chunk of code should be documented using
phpDocumentator or PHPLint (this latter is mine :-). Every programmer using
these tools should rely on the interface specified in the documentation,
and this documentation should be always available on-line via WEB.

7) Submit your program to a formal validator, as PHPLint.

8) Keep every project under a release version system like CVS. It is really
useful also when there is only one developer.
