I want to retrieve the first 10k bytes from a URL with curl (using PHP in my case). Is there a way to specify this? I thought CURLOPT_BUFFERSIZE would do this, but it just appears to determine the size of a buffer that is reused until all of the content is retrieved.

This is how i do it in c++
int offset = 0; int size = 10*1024; char range[256]; curl_slist_s *pHeaders = NULL; snprintf(range, 256, "Range: bytes=%d-%d", offset, offset+size-1); pHeaders = curl_slist_append(pHeaders, range); curl_easy_setopt(pCurlHandle, CURLOPT_HTTPHEADER, pHeaders); curl_slist_free_all(pHeaders); pHeaders = NULL;
Edit: Just found out you meant in php. Ill see if i can find out how to port it.
Think this should work in php:
$offset = 0; $size = 10*1024; $a = $offset; $b = $offset + $size-1; curl_easy_setopt(curlHandle, CURLOPT_HTTPHEADER, array("Range: bytes=$a-$b") );
