I wrote this code to integrate with filepicker.io, it takes the URL of the file and gets the header information:

$info = curl_init() or die('error 1');
        curl_setopt($info, CURLOPT_RETURNTRANSFER, 1);
        //curl_setopt($info, CURLOPT_PORT , 8089);
        curl_setopt($info, CURLOPT_URL, $url);
        curl_setopt($info, CURLOPT_CONNECTTIMEOUT, 30);
        curl_setopt($info, CURLOPT_NOBODY, true);
        //curl_setopt($info, CURLOPT_SSL_VERIFYPEER, 0);
        curl_exec($info);
        if(!curl_errno($info)){
            $response = curl_getinfo($info);
            echo "<pre>";
            echo var_dump($response);
            echo "</pre>";
        }else{
            echo "error!";
            echo "<br>" . curl_error($info);
        }

And here is a response:

array(26) {
  ["url"]=>
  string(55) "https://www.filepicker.io/api/file/CjDfxG0WSmGiY3O2eKDE"
  ["content_type"]=>
  string(9) "image/png"
  ["http_code"]=>
  int(200)
  ["header_size"]=>
  int(840)
  ["request_size"]=>
  int(86)
  ["filetime"]=>
  int(-1)
  ["ssl_verify_result"]=>
  int(0)
  ["redirect_count"]=>
  int(0)
  ["total_time"]=>
  float(2.805141)
  ["namelookup_time"]=>
  float(0.442366)
  ["connect_time"]=>
  float(0.46781)
  ["pretransfer_time"]=>
  float(0.873621)
  ["size_upload"]=>
  float(0)
  ["size_download"]=>
  float(0)
  ["speed_download"]=>
  float(0)
  ["speed_upload"]=>
  float(0)
  ["download_content_length"]=>
  float(965985)
  ["upload_content_length"]=>
  float(0)
  ["starttransfer_time"]=>
  float(2.805054)
  ["redirect_time"]=>
  float(0)
  ["certinfo"]=>
  array(0) {
  }
  ["primary_ip"]=>
  string(11) "79.125.4.68"
  ["primary_port"]=>
  int(443)
  ["local_ip"]=>
  string(11) "192.168.0.9"
  ["local_port"]=>
  int(51414)
  ["redirect_url"]=>
  string(0) ""
}

There is one massive thing missing - the file name, as I understand it that should be returned with the header or do I have to make a specific request for it. The filename is masked in the URL so I cannot use that.
Any suggestions would be great!

The link gives me...

<img src="https://www.filepicker.io/api/file/CjDfxG0WSmGiY3O2eKDE" width="727" height="409">

I imagine that the rewritten url passes the info to a php (or similar) script to retrieve info either directly from the DB (blob) or even from a stored file and then transformed. Either way, I don't see how you could retrieve a filename for it, as the 'file' itself may not exist.

I've managed to get the header data but I need only the filename and I can't use http_parse_headers. Any ideas?

Here's the response

EDIT: Just to clarify, this is for a client who wants it to run of shared hosting, and this particular shared hosting doesn't support the http php library.

Use regex if the above is in a string.

Find 'filename="' extract the content before the next '"'

$pattern = '/filename=\"(.*)\"/';
//subject will be the header in string

preg_match($pattern, $subject, $matches);

echo $matches[1];
