CURL is not providing any values - php

Question

my below code of PHP is not working. I have created test user id & password which is shared in the code. The file is not having any value. But I see with this code it is edited every time when I execute this code.
<?php
$username = '8632465';
$password = 'basade41';
$loginUrl = 'https://cabinet.instaforex.com/partner/login';
//$userAgent = 'Mozilla/5.0 (Windows NT 5.1; rv:31.0) Gecko/20100101 Firefox/31.0';
$config['useragent'] = 'Mozilla/5.0 (Windows NT 6.2; WOW64; rv:17.0) Gecko/20100101 Firefox/17.0';
//$userAgent = $_SERVER['HTTP_USER_AGENT'];
//init curl
$ch = curl_init();
curl_setopt($ch, CURLOPT_USERAGENT, $config['useragent']);
//Set the URL to work with
curl_setopt($ch, CURLOPT_URL, $loginUrl);
// ENABLE HTTP POST
curl_setopt($ch, CURLOPT_POST, 1);
//Set the post parameters
curl_setopt($ch, CURLOPT_POSTFIELDS, 'user='.$username.'&pass='.$password);
//Handle cookies for the login
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
//Setting CURLOPT_RETURNTRANSFER variable to 1 will force cURL
//not to print out the results of its query.
//Instead, it will return the results as a string return value
//from curl_exec() instead of the usual true/false.
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
//execute the request (the login)
$store = curl_exec($ch);
//the login is now done and you can continue to get the
//protected content.
//set the URL to the protected file
curl_setopt($ch, CURLOPT_URL, 'https://cabinet.instaforex.com/partner/aff_statistic');
//execute the request
$content = curl_exec($ch);
//save the data to disk
file_put_contents('c:/xampp/htdocs/upload/test.txt', $content);
?>

I think your code missing some settings. eg:CURLOPT_CAINFO...
This is my https code
<?php
//The CA certificate path
$caDir = '....../GeoTrustGlobalCA.crt';
//cookie file path
$cookieDir = '......';
//URL
$url = 'https://www.zhihu.com/......';
$defaultOpt = 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 => "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/47.0.2526.80 Safari/537.36",
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 => true, // enabled SSL Cert checks
CURLOPT_SSL_VERIFYHOST => 2,
CURLOPT_CAINFO => $caDir,
CURLOPT_COOKIEFILE => $cookieDir,
CURLOPT_COOKIEJAR => $cookieDir,
CURLOPT_URL => $url,
CURLOPT_HTTPGET => true //method is GET
);
$handle = curl_init();
curl_setopt_array($handle,$arrOpt);
$content = curl_exec($handle);
$err = curl_errno($handle);
$errmsg = curl_error($handle);
$header = curl_getinfo($handle);
curl_close($handle);
printf("Content is %s", $content);
?>
