Answer 1

您需要执行一个POST 到http://aftabcurrency.com/login_script.php 您的 curl 还需要接受 cookie。
身份验证后，脚本将重定向您，因此您还需要添加 CURLOPT_FOLLOWACTION。

这是你的脚本的编辑版本，我无法在 http://aftabcurrency.com/ 上测试它希望它有效:

$url = "http://aftabcurrency.com/login_script.php";

$ch = curl_init();    
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 

curl_setopt($ch, CURLOPT_URL, $url); 
$cookie = 'cookies.txt';
$timeout = 30;

curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_TIMEOUT,         10); 
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT,  $timeout );
curl_setopt($ch, CURLOPT_COOKIEJAR,       $cookie);
curl_setopt($ch, CURLOPT_COOKIEFILE,      $cookie);

curl_setopt ($ch, CURLOPT_POST, 1); 
curl_setopt ($ch,CURLOPT_POSTFIELDS,"user_name=user&user_password=pass&passcode=code");     

$result = curl_exec($ch);

/* //OPTIONAL - Redirect to another page after login
$url = "http://aftabcurrency.com/some_other_page";
curl_setopt ($ch, CURLOPT_POST, 0); 
curl_setopt($ch, CURLOPT_URL, $url);
$result = curl_exec($ch);
 */ //end OPTIONAL 

curl_close($ch); 
echo $result;
