pulling variables from other servers

[Q695]

I'm working on a project that requires people to post some data on other servers to just add particular features.  How would I most easily pull the variables onto my server with every click that is done?

XML is the preferred porting method to bridge languages/servers.

 

 

If its MySQL and you have rights to read said database that is another way to do it.

 

 

If you own the other server there are tons of ways to do it

 

If not you need to figure out the data and its format

you can have the remote server post data to your server via cURL. just pick a common format like XML or JSON.

 

or you can have the users send you the data every page visit via JavaScript (kind of like Google Analytics). Basically you load a PHP file as a JavaScript file.

 

What kind of 'variables' are you looking to send?

Can I see the curl syntax, because I've never done it before?

 

I'm building an application that could be used on other sites by simply doing a simple inclusion statement.

on the remote servers, that are posting data, it would look like this:

<?php
  $data = array(
    'key1' => 'value1',
    'key2' => 'value2',
  );

  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL,"http://www.yourserver.com/page.php");
  curl_setopt($ch, CURLOPT_POST, 1);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
  $output = curl_exec($ch);      
  curl_close($ch);
  echo $output;
?>

 

and then on your server, in page.php, you can access the data via $_POST

 

if you elaborate more on what you are trying to do i can have a better recommendation on what to do...
