The code above is to send an HTTP POST data to a file on my server. It works fine and very well but I just have a problem with fsockopen.

I have a server that has many domain names registered under it. The above example works fine but if I change the host name to another domain on my server, it will always bounce back to the domain above (xyz.com).

I discovered that all the domain names on my server resolve to only one IP address and this IP address in turn resolves to only one hostname (xyz.com).

So what I need is a way to tell fsockopen to open exactly the domain name I specify as my host name and not the default domain name on my server. Remember I have many domain names on my server.

Please is there a way to get around this. Please I need help as urgent as possible

My head is craking over here.

Try fsockopen('http://www.domain.com').

The problem is most likely that the Host: header, which tells a webserver which site to server, is invalid.  The server then falls back to serving the default site.  If none of this works, try using the CURL functions.
