如果https未包含在URL中，则为cURL

I use the following PHP curl request to scrap the data from a remote website:

$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_URL, $URL);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); // Skip SSL Verification
$rsData = curl_exec($ch);
curl_close($ch);
return $rsData;

Now when I try to scrape the data from https://www.dsebd.org, I have to mention https:// in the $URL. Without mentioning the https://, no data is retrieving. But as far I can understand, as CURLOPT_SSL_VERIFYPEER is set to 0, I can omit the https:// from the $URL.

Then, why the CURLOPT_SSL_VERIFYPEER is not working in my case?
