2. Set HTTP header to support PHP Curl Access LIGHTTPD Server

 
  
  

  
   
   
$header []= ' Expect: '; 
 
  
  

3. Set curl to get the HTTP header only, without getting the body:

 
  
  

  
   
   
curl_setopt ($ch, Curlopt_header, 1); 
  
   
   
curl_setopt ($ch, curlopt_nobody, 1); 
 
  
  

Or just get body:

 
  
  

  
   
   
curl_setopt ($ch, Curlopt_header, 0); 
Make sure we get the body 
  
   
   
curl_setopt ($ch, curlopt_nobody, 0); 
 
  
  

4. To access the virtual host, you need to set the host

 
  
  

  
   
   
$header []= ' Host: '. $host; 
 
  
  

5. Use a restful way to access the URL using post, put, delete, etc.

 
  
  

  
   
   
Post 
  
   
   

  
   
   
 curl_setopt ($ch, Curlopt_post, 1); 
  
   
   

  
   
   
Put, delete: 
  
   
   

  
   
   
 curl_setopt ($ch, Curlopt_customrequest, "DELETE"); 
Or put, you need the server to support these methods. 
 
  
  

6. PHP Curl saves the downloaded content as a file

 
  
  

  
   
   
curl_setopt ($ch, Curlopt_file, $fp);
