fputs($file, $data);
fclose($file);

Answer 1

I solved this problem using this:

curl_setopt($ch, CURLOPT_SSLVERSION,3);

This is the final code:

$source = "https://myapps.gia.edu/ReportCheckPortal/downloadReport.do?reportNo=1152872617&weight=1.35";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $source);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSLVERSION,3);
$data = curl_exec ($ch);
$error = curl_error($ch); 
curl_close ($ch);

$destination = "./files/test.pdf";
$file = fopen($destination, "w+");
fputs($file, $data);
fclose($file);

Answer 2

Your url using https connection. Use the following curl option as well.

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER,false);

Answer 3

1. Did you check if result actually contains data?
2. with fputs on larger files you need to specify byte length
3. Try using file_put_contents($destination, $data);

Answer 4

See if you can use the following code to help you.

//Create a cURL handle. $ch = curl_init($fileUrl);

//Pass our file handle to cURL. curl_setopt($ch, CURLOPT_FILE, $fp);
