Force curl to download page as browser - php

Question

How to force curl (with) PHP to download page as browser? The page I want to download is a price comparator, for e.g. http://www.ceneo.pl/22416171. It's public, anybody can access site.
To check if the curl downloading is even possible, I typed on my Debian-based local server
curl http://www.ceneo.pl/22416171
And it worked perfectly. But I do need to use it on my Virtual PHP-Apache serv, so I need to use PHP to do it.
While trying to download page as PHP-based curl, it gives me nothing, opposite to shell curl.
Why? How can I get the right content on PHP?
Tried:
<?php
$curl = curl_init(http://www.ceneo.pl/22416171);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_HEADER, 1);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl,CURLOPT_HTTPHEADER,
array(
'User-Agent: Mozilla/5.0 (Windows NT 6.0; rv:28.0) Gecko/20100101 Firefox/28.0',
'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
'Accept-Language: pl,en-US;q=0.7,en;q=0.3',
'Accept-Encoding: gzip, deflate',
'p3p: CP="NOI CURa ADMa DEVa TAIa OUR BUS IND UNI COM NAV INT"',
'Vary: Accept-Encoding',
'Content-Type: text/html; charset=utf-8',
'Cache-Control: private'
));
$body = curl_exec($curl);
curl_close($curl);
echo $body;
?>
I tried also to use
<?php exec(curl http://www.ceneo.pl/22416171); ?>
But it gave
curl: /usr/local/lib/libcurl.so.4: no version information available (required by curl)

Take a look at the documentation: http://www.php.net/manual/en/curl.examples.php
This is how you do it:
test.php
<?php
// create curl resource
$ch = curl_init();
// set url
curl_setopt($ch, CURLOPT_URL, "http://www.ceneo.pl/22416171");
//return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
//set headers
curl_setopt($ch,CURLOPT_HTTPHEADER, array(
'User-Agent: Mozilla/5.0 (Windows NT 6.0; rv:28.0) Gecko/20100101 Firefox/28.0',
'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
'Accept-Language: pl,en-US;q=0.7,en;q=0.3',
//'Accept-Encoding: gzip, deflate',
'p3p: CP="NOI CURa ADMa DEVa TAIa OUR BUS IND UNI COM NAV INT"',
'Vary: Accept-Encoding',
'Content-Type: text/html; charset=utf-8',
'Cache-Control: private'
));
// $output contains the output string
$output = curl_exec($ch);
// close curl resource to free up system resources
curl_close($ch);
// debug
echo $output;
Demo of it working (only the html output from the site is retrieved):
