PHP: read a remote file (ideally using fopen)

I'd like to read a remote text file (ideally using fopen) using PHP. My script works using fopen when I'm using this function on a local file.

I've tried:

$file = fopen ("http://abc.abc.abc", "r");
if (!$file)
echo "<p>Unable to open remote file.n";
exit;



and I got:

Warning: fopen(http://abc.abc.abc): failed to open stream: No connection could be made because the target machine actively refused it. in C:xampphtdocsNMRnmrTest5.php on line 2 Unable to open remote file.

I've read that phpseclib could be a good option and since I can access to my files using WinSCP (SFTP) or by using Puttyfor I tried this (after copying all the files from phpseclib to my directory) hoping that I could copy locally the file and then read it with fopen (not the best thing for met but I could live with that):

include('Net/SFTP.php');

$sftp = new Net_SFTP('abc.abc.abc');
if (!$sftp->login('username', 'pass'))
exit('Login Failed');



and I got:

Notice: No compatible server to client encryption algorithms found in C:xampphtdocsNMRNetSSH2.php on line 1561
Login Failed

Interstingly, I got a different message if I was connected to the server (using WinSCP):

Notice: Error reading from socket in C:xampphtdocsNMRNetSSH2.php on line 3362

Notice: Connection closed by server in C:xampphtdocsNMRNetSSH2.php on line 1471
Login Failed

Any idea on how I could get it to work? Ideally I would use fopen but I'm open to other solution.

I have faced similiar issues with fopen.
Curl is useful for these purposes.

Please check with the following basic example function(if the url is https, please uncomment the CURLOPT_SSL_VERIFYPEER = FALSE line).

$url = '***THE URL***';
$result = get_web_page_by_curl($url);

if ($result['errno'] != 0) echo 'error: bad url, timeout, redirect loop ...';
if ($result['http_code'] != 200) echo 'error: no page, no permissions, no service ...';
else
$page = $result['content'];
echo $page;


function get_web_page_by_curl($url)
$agent = "Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4) Gecko/20030624 Netscape/7.1 (ax)";

$options = array(
CURLOPT_RETURNTRANSFER => true, // return web page
CURLOPT_HEADER => false, // don't return headers
CURLOPT_FOLLOWLOCATION => true, // follow redirects
CURLOPT_ENCODING => "", // handle all encodings
CURLOPT_USERAGENT => $agent, // who am i
CURLOPT_AUTOREFERER => true, // set referer on redirect
CURLOPT_CONNECTTIMEOUT => 120, // timeout on connect
CURLOPT_TIMEOUT => 120, // timeout on response
CURLOPT_MAXREDIRS => 10, // stop after 10 redirects
//CURLOPT_SSL_VERIFYPEER => FALSE // this line makes it work under https
);

$ch = curl_init($url);
curl_setopt_array($ch, $options);
$content = curl_exec($ch);
$err = curl_errno($ch);
$errmsg = curl_error($ch);
$header = curl_getinfo($ch);
curl_close($ch);

$header['errno'] = $err;
$header['errmsg'] = $errmsg;
$header['content'] = $content;
return $header;
