sockets update


(original is here)

I looked up what SOL_TCP should be (6), and tried that instead. The result was:
Warning: socket_create() Unable to create socket [0]: The requested service provider could not be loaded or initialized...

Then I tried running my script on the command line:
----
C:\Program Files\Apache Software Foundation\Tomcat 5.0\webapps\phpservlet\test>php index.php
Content-type: text/html
X-Powered-By: PHP/4.3.8

2<br>1<br>6

Madness!

Then I had a poke around in the php source code. The following is in ext/sockets/sockets.c (apologies for the formatting):
----

So there was something wrong with the underlying sockets code, and I was beginning to suspect that Tomcat was doing something java-sandbox like and not allowing socket creation, or at least not passing the requests down to the windows socket layer.

*sigh*

I tried running it under Apache, and it worked fine. I still need Tomcat for some servlet stuff, so I think I'm going to have to use both of them. Which is a pain because it rather complicates things. Ho hum.

If anyone has any suggestions, then do shout up :-)

In any case, thanks very much for all your help in my getting this far.
