Fetch content of google scholar page with php - php

Question

This is my journal page in Google Scholar:
https://scholar.google.com/citations?user=F4z6guYAAAAJ
I can check the page with browser. But can not get contents by PHP (Curl or File_get_contents)
I tried many headers but was not useful.
Update : My code is here:
$fgc_context = stream_context_create(array(
'http'=>array(
'method'=>"GET",
'header'=>"Accept: text/html,application/xhtml+xml,application/xml\r\n" .
"Accept-Charset: ISO-8859-1,utf-8\r\n" .
"Accept-Encoding: gzip,deflate,sdch\r\n" .
"Accept-Language: en-US,en;q=0.8\r\n",
"timeout" => 60,
'user_agent'=>"user_agent', 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.9) Gecko/20071025 Firefox/2.0.0.9\r\n"
)
));
ini_set('user_agent', 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.9) Gecko/20071025 Firefox/2.0.0.9');
$wcnt = #file_get_contents($the_journal_url, false, $fgc_context);
And google return a page ends with:
<H1>Server Error</H1> We're sorry but it appears that there has been an internal server error while processing your request. Our engineers have been notified and are working to resolve the issue.<p>Please try again later.</p>

Try with this code :
(run it 2 times to create the cookie the first time)
$cookie = __DIR__ . '/cookie.txt';
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_URL, 'https://scholar.google.com/citations?user=F4z6guYAAAAJ');
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:42.0) Gecko/20100101 Firefox/42.0');
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
$data = curl_exec($ch);
curl_close($ch);
echo $data;
