How do I POST values to a URL from PHP?

[Anon]

Hi,
the usual way to POST information to a URL
is using a form in html:

<form method="POST" action="http://www.xxx.com" etc...
and then the server returns another html page as the reply.

Instead of this, I want to POST the information, for example
var1=value1
var2=value2
from my PHP code on the fly to an URL, and I
don't care about the return page and status.

How can I do this?

There must be a function along these lines:
httppost("http://www.xxx.com", "var1=value1,var2=value2");

but I have not been able to find it
in the manual.
Any hint or example would be dearly
appreciated.

you can use the header function to fake a GET request:

header ('location: http://www.domain.com/file.php?var1=value1&var2=value2');

Are you trying to use POST with forms and such or are you trying to put variables into a link, such as "http://www.bla.com/test.php?var=5"?

I want to send information to a
web site (a URL). This URL is a shopping
cart, which receives POSTed information from
a form.

But I don't want to use the form. I just want
to add items to the cart directly, from
the PHP code, and I just will ignore the
returned page, which will not be displayed to
the user.

I don't have access to the code of the shopping
cart. The only thing I can do is to send the
info via POST.

Mmmm, yes, but what I have to fake is a
POST request.

If I had to fake a GET I would simply do
fopen("http://www.dom.com/file.html?var=val",
"r");
and that's it.

But I don't know how to do it for a POST...

what you can do is this ... I don't know if you can call JavaScript from php or if you can do this with php, but the psuedocode is as follows:

open a window with the fake post URL (e.g. self.location='http://www.xxx.com/action.php?var1=3') and specify a name for the window. (e.g. window.open("ShoppingCart", "http://www.xxx.com/action.php?var1=3")
then close the window.

If you do that, the page will post what needs to be posted and the window will never be seen.
