Communication of the backend via php

dorgon

I have no ideas for following question, please tell me the solution. Wait for your helps!!!

Under the backend, how to edit the receive.php which will transfer parameters to following IP address(virtual) automatically while it get the info from gateway?

http://2.2.2.2/retrieve.php?sp=100&msg=ok

Assume following IP address (virtual) will not be opened by any browsers.

http://1.1.1.1/receive.php
And the backend of gateway will send php program the parameters $sp=100 and $msg=ok. The gateway will transfer them via POST with trigger. Meanwhile the receive.php will get data from gateway automatically, and insert them to MySQL…

Remark:

1)the function header(sprintf(“location:%s”,$insertGoTo)); is not workable, and any methods of jumping are no execution for browser.

2)my goal is establish the connection between gateway and the IP address http://2.2.2.2/retrieve.php for exchange of the info.not means between IP addresses( http://1.1.1.1/receive.php and http://2.2.2.2/retrieve.php).

I'm not sure that I fully understand, but it sounds like you want to create a "man in the middle". So that when I call http://2.2.2.2/retreive.php, it then calls http://1.1.1.1/receive.php

It would

See this example from the user comments on the curl() manual page

<?p
$url="http://anything";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_POST, 1);
curl_setopt ($ch, CURLOPT_POSTFIELDS, "fieldname=fieldvalue&fieldname=fieldvalue&");
#curl_setopt ($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
$store = curl_exec ($ch);
$content = curl_exec ($ch); # This returns HTML
curl_close ($ch);
?>

This shows you how to post values to the 1.1.1.1 page. You just have to extract the variables sent to the 2.2.2.2 page and insert them into CURLOPT_POSTFIELDS.

The response to this will be a the html from the 1.1.1.1 page. What you do with tat output is up to you.

if you display it, your user will get a page that looks like the 1.1.1.1 page and is full of links to the 1.1.1.1 page.

You could rewrite this to change all the 1.1.1.1 references to 2.2.2.2 but this is a lot of work and very, very fragile.

Thanks for your solution,I think I would not expatiate on my goal.Now I have updated term 2 of the remark.

Else,the cURL() & the fsockopen() was taken them a try.But they was unworkable.

Thanks for your reply.Concerning the problem,I have resolved it. pick the funtion fopen("http://2.2.2.2/retrieve.php?msg=000","r"); done.

That works if the script you are calling accepts GET parameters. I had thought we had to use POST - hence the slight;y more complicated code.

Thanks for letting me know how you got on.
