Question

I am trying to send username and password parameters to a url using curl, and I want to retrieve them. I send the parameters to a page, like the following:

<?php

$curl = curl_init('http://localhost/sample.php');
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);                         
curl_setopt($curl, CURLOPT_USERPWD, 'key:123456');
curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_ANY);                    
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);                          
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);                           
curl_setopt($curl, CURLOPT_USERAGENT, 'Sample Code');

$response = curl_exec($curl);                                          
$resultStatus = curl_getinfo($curl);                                   

if($resultStatus['http_code'] == 200) {
    echo $response;
} else {
    echo 'Call Failed '.print_r($resultStatus);                         
}
?>

Now in the sample.php page, how can I retrieve those parameters?
(here, username is key, password is 123456).

I suppose they must be available in the $_SERVER array, but they are not available.

By default, cURL issues an HTTP GET request. In this case, you’d have to append the parameters to the URL you’re calling:

$curl = curl_init('http://localhost/sample.php?foo=bar&baz=zoid');

In sample.php, $_GET['bar'] and $_GET['baz'] would be available respectively. If it’s a POST request, you want to issue, you’ll need to set the parameters via curl_setopt:

$curl = curl_init('http://localhost/sample.php');
curl_setopt($curl, CURLOPT_POSTFIELDS, 'foo=bar&baz=zoid');
