....
  
  
$Ch=Curl_init();
  
  
Curl_setopt ($ ch, CURLOPT_HTTPHEADER, $ header); // sets the http header
  
  
Curl_setopt ($ ch, CURLOPT_ENCODING, "gzip ");
// Set the client to support gzip Compression

}
  
  
Fclose ($ fp );
  
  

  
  
$Curl_code=Curl_getinfo($ Ch, CURLINFO_HTTP_CODE );
// Obtain the http Return Value
  
  
If ($Curl_code= 200 ){
  
  
// Normal access url
  
  
}

2. Set http header to support php curl access to the lighttpd Server

 
 

  
  
$header[]= 'Expect:';  
 
 

3. Set curl to get only the http header and not the body:

 
 

  
  
curl_setopt($ch, CURLOPT_HEADER, 1);       
  
  
curl_setopt($ch, CURLOPT_NOBODY, 1);      
 
 

Or you can only get the body:

 
 

  
  
curl_setopt($ch, CURLOPT_HEADER, 0);   
// make sure we get the body     
  
  
curl_setopt($ch, CURLOPT_NOBODY, 0);     
 
 

4. To access the VM, you must set the Host

 
 

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

5. Use post, put, delete and other REStful access URLs

 
 

  
  
Post:
  
  
 
  
  
Curl_setopt ($ ch, CURLOPT_POST, 1 );
  
  
 
  
  
Put, delete:
  
  
 
  
  
Curl_setopt ($ ch, CURLOPT_CUSTOMREQUEST, "DELETE ");
// Or PUT, which must be supported by the server.
 
 

6. php curl saves the downloaded content as a file

 
 

  
  
curl_setopt($ch, CURLOPT_FILE, $fp);
