Retrieve username, password parameters passed through curl - php

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.

Answer 1

Some of the parameters, like CURLOPT_USERAGENT are send in the HTTP headers and can be retrieved using special globals like $_SERVER['HTTP_USER_AGENT'] (see http://www.php.net/manual/de/reserved.variables.server.php).
Others, like CURLOPT_SSL_VERIFYPEER are only local to CURL and don't get send to the server.

Answer 2

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');

Answer 3

to send parameters to a web page you can use 1 of two methods GET or POST
GET is where the parameters are appended to the name of the resource you are getting
e.g $url = "http://localhost/sample.php?name=" . urlencode( $value )
the other choice is via a POST. post is sent to the server as a page of information to do this with curl you create a post with
curl_setopt($ch, CURLOPT_POSTFIELDS, 'name=' . urlencode( $value ) . '&name2=' . urlencode( $value2 ));
If on the other hand you are talking about Headers, then you can access them through the $_SERVER['headername'] array.

Answer 4

you can find the username and password in the global $_SERVER array
$_SERVER : array
(
....
'PHP_AUTH_USER' => 'the_username'
'PHP_AUTH_PW' => 'the_password'
)
