用PHP发布并获得结果

Question

From a PHP page, I'm trying to POST some data to another PHP page and get data back.

Here is what I currently have:

<?php 
// Initialize cURL session
$ch = curl_init('postpage.php');

// Set some options on the session
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, array('field1' => 'Andrew'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// Execute post
$result = curl_exec($ch);

var_dump($result);

// Close the session
curl_close($ch);
?>

and in postpage.php:

<?php
echo 'Receipt of post request. field1:'.$_POST["field1"];
?>

All the var_dump gives me is this:

string(0) "" 

Why am I not getting the text back?

Thanks!

The curl executed from your php script is not aware of the current environment, that is, you cannot use relative urls. The url you supply to curl_init must be absolute (i.e. including http://)
