Php curl error Url not found on this server - php

Question

I am working on core php.
I am requesting a URL by curl. This is working on my development server but same thing are not working on live server.
Below is my Code:
$url = "http://www.streamatemodels.com/login.php";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 15);
curl_setopt($ch, CURLOPT_AUTOREFERER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 15);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, 'submitted=1&g=&sausr='.urlencode('username').'&sapwd='.urlencode('password').'');
$result = curl_exec($ch);
$error = curl_errno($ch);
$code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
print_r($result);
Please help me if anyone have solution.
Update
I checked this with new username and password but same things happen. Its working on my development server but not working on live and local host.

Answer 1

The following line:
curl_setopt($ch, CURLOPT_POSTFIELDS, 'submitted=1&g=&sausr='.urlencode('username').'&sapwd='.urlencode('password').'');
should be changed to:
curl_setopt($ch, CURLOPT_POSTFIELDS, 'submitted=1&g=&sausr='.urlencode($username).'&sapwd='.urlencode($password).'');
If it still doesn't work try to create the query-string outside of curl_setopt:
$params = 'submitted=1&g=&sausr='.urlencode($username).'&sapwd='.urlencode($password).'';
curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
Another advise: it's better practice to use http_build_query($params)
UPDATE
I had the time to check the code, and it works fine on my local host (meaning: check your username/password!):
