I solved this problem using this:
我用这个解决了这个问题：
curl_setopt($ch, CURLOPT_SSLVERSION,3);
This is the final code:
这是最终的代码：
$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);

Your url using https connection. Use the following curl option as well.
您的网址使用 https 连接。也使用以下 curl 选项。
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER,false);

- Did you check if result actually contains data?
- with
fputson larger files you need to specify byte length - Try using
file_put_contents($destination, $data);
- 您是否检查过结果是否确实包含数据？
- 与
fputs上更大的文件，你需要指定字节长度 - 尝试使用
file_put_contents($destination, $data);
