Get currency exchange rate from bank site - php

Question

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.
