I have a call to open a socket that works using tcp:

$s = fsockopen("tcp://siteaddr",80,$errno,$errmsg,20);

But if I change it to "ssl:"... it fails. $s comes back false, and $errno is 0. The doc says that this set of return values "is most likely due to a problem initializing the socket." Great.

Can someone suggest places to look to figure out what the problem might be? I have the openssl package enabled in php, if that matters.

If I go to a browser and invoke the site using "http" and "https" it works in both cases (but it does warn about ssl certificate issues if using https). Is this a clue, or is this irrelevant?

Thanks in advance...

Some more info:
This is on PHP version 4.3.4, using the Windows binaries downloaded from the PHP.net site.
PHPINFO says OpenSSL Support is "enabled" and is version 0.9.7b. There are no other parameters shown in PHPINFO for openssl.

When I change the protocol from "tcp" to "ssl", I'm also changing the port to 443 (but 80 doesn't work either).

This problem is solved... In case someone else sees this topic and wants to know what the answer is:

In another forum, I was referred to a comment at the bottom of the php manual page for "supported protocols and wrappers" (Appendix I). http://www.php.net/manual/en/wrappers.php

A user comment there notes that SSL doesn't work on Windows with the standard php4ts.dll, and it refers one to another site where a "fixed" dll can be downloaded. Did that, and everything started to work.

Thanks dawg. That was very helpful.
