Retrieve cookies from remote host and pass them back to client - php

I'm trying to grab cookies from a remote host with a little script which works well:
// create a new cURL resource
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_HEADER, TRUE);
curl_setopt($ch, CURLOPT_NOBODY, TRUE);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($ch, CURLOPT_COOKIE, TRUE);
// grab URL and pass it to the browser
$opt = curl_exec($ch);
// close cURL resource, and free up system resources
curl_close($ch);
I would like to know how I can pass them back to the client?

Sending POST data to HTTPS redirect PHP

I need to redirect the current user to an external page (other domain) with some parameters that will be used on that page. To do that I'm using cURL, an example code is below:
$postfields = array('key'=>'value');
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://domain.com/example.aspx');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($postfields));
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); // On dev server only!
$result = curl_exec($ch);
curl_close ($ch);
But the user stays on the same page and I don't know if any data is transmitted.
What is the problem here? Is there another way to do that?

PHP cURL Proxy Inquiry

$url = 'http://dynupdate.no-ip.com/ip.php';
$proxy = '127.0.0.1:8888';
//$proxyauth = 'user:password';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
//curl_setopt($ch, CURLOPT_PROXYUSERPWD, $proxyauth);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
$curl_scraped_page = curl_exec($ch);
curl_close($ch);
echo $curl_scraped_page;
How would I make this continuously connect to this server?
I'm working on a bot for this site to improve the technology. Also, how would I authenticate cookies on the server, for example: I send a request to the server with this script using the certain cookies I would like to use.
There is an option called CURLOPT_COOKIEJAR where you can set the file that contains the cookie:
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
Once you get the cookie you have to use the same $ch variable to keep the connection.
You can found a complete example of cURL usage here: http://blog.binacube.com/2014/08/complete-curl-example-login-proxy-and.html

Get currency exchange rate from bank site

I'm trying to get content from bank site using curl.
http://www.zaba.hr/home/wps/wcm/connect/zaba_hr/zabapublic/tecajna
Site is specific becouse it using ajax to fill currency exchange table. There is a link for download data in to file but you have to have same session id to able to do that.
Im trying this code:
$url="http://www.zaba.hr/home/wps/wcm/connect/zaba_hr/zabapublic/tecajna";
$useragent = $_SERVER['HTTP_USER_AGENT'];
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, $useragent);
curl_setopt($ch, CURLOPT_URL,$url);
$cl = curl_exec($ch);
$dom = new DOMDocument();
#$dom->loadHTML($cl);
#$link = $dom->getElementById('tecajPrn');
echo $suburl = "http://www.zaba.hr".$link->getAttribute('href');
After this I got link to file but I can't open it.
Another strange situation is that link I got with curl is http://www.zaba.hr/home/ZabaUtilsWeb/utils/tecaj/danasPrn but real link when I click on icon is http://www.zaba.hr/ZabaUtilsWeb/utils/tecaj/prn/62/2014
You are messing with cookie and ajax(may be!). Here is the lookaround. Try this:
First send a request to the page to obtain the cookie.
$url="http://www.zaba.hr/home/wps/wcm/connect/zaba_hr/zabapublic/tecajna";
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, "mozilla 5.0");
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_COOKIEFILE,"cookie.txt");
curl_setopt($ch, CURLOPT_COOKIEJAR,"cookie.txt");
$cl = curl_exec($ch);
curl_close($ch);
After that make another curl request. This time to obtain the json data:
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, "mozilla 5.0");
curl_setopt($ch, CURLOPT_HTTPHEADER, array("X-Requested-With: XMLHttpRequest", "Referer: http://www.zaba.hr/home/wps/wcm/connect/zaba_hr/zabapublic/tecajna"));
curl_setopt($ch, CURLOPT_URL,"http://www.zaba.hr/ZabaUtilsWeb/utils/tecaj/danas");
curl_setopt($ch, CURLOPT_COOKIEFILE,"cookie.txt");
curl_setopt($ch, CURLOPT_COOKIEJAR,"cookie.txt");
$cl = curl_exec($ch);
curl_close($ch);
Your json is available at this variable. Parse it using json_decode()
// now parse json from $cl
print $cl;
Anything required, help yourself straightway!
Note: Make sure you have write permission for the cookie.txt file. Also, its better to use absolute path like c:/test/cookie.txt or /var/tmp/cookie.txt.

opening a page after another with curl

I want to open a page from a site and save the cookies. Then open another page with those cookies.(It doesn't let me to visit the second page without the first page's cookies)
I tried this code but it didn't work.
$ch = curl_init();
curl_setopt($ch, CURLOPT_COOKIESESSION, 1);
curl_setopt($ch, CURLOPT_COOKIEFILE, 'cook.txt');
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cook.txt');
curl_setopt($ch, CURLOPT_URL, 'url');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_exec($ch);
curl_setopt($ch, CURLOPT_COOKIESESSION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, 'nexturl');
$rs = curl_exec($ch);
echo $rs;
End of your each curl operation close the curl handle. Otherwise it will not save the cookie into the file.
$rs = curl_exec($ch);
curl_close($ch);
Now initiate second curl, and send the request. It should work now.
