Using cURL to download a file programmatically

Using cURL to download a file programmatically

For windows: In order to enable this module on a Windows environment, you must copy 
                libeay32.dll and ssleay32.dll from the DLL folder of the PHP/Win32 binary 
                package to the SYSTEM folder of your Windows machine. 
                (Ex: C:\WINNT\SYSTEM32 or C:\WINDOWS\SYSTEM) 

 Uncomment the cURL extension in the php.ini file: 
   extension=php_curl.dll 

Functionality: 
1. Its a function and accepts three parameters (you can, of course, change this) 
   get_file1($file, $local_path, $newfilename) 
   $file        : is the filename of the object to be retrieved 
   $local_path  : is the local path to the directory to store the object 
   $newfilename : is the new file name on the local system 

2. To use it: 

   <? 
   $wav_file = get_file1($filename, $local_path, $newfilename); 
   ?> 
   cURL returns true on success and false on failure. 

The function: 

<? 
function get_file1($file, $local_path, $newfilename) 
{ 
    $err_msg = ''; 
    echo "<br>Attempting message download for $file<br>"; 
    $out = fopen($newfilename, 'wb'); 
    if ($out == FALSE){ 
      print "File not opened<br>"; 
      exit; 
    } 
     
    $ch = curl_init(); 
            
    curl_setopt($ch, CURLOPT_FILE, $out); 
    curl_setopt($ch, CURLOPT_HEADER, 0); 
    curl_setopt($ch, CURLOPT_URL, $file); 
                 
    curl_exec($ch); 
    echo "<br>Error is : ".curl_error ( $ch); 
     
    curl_close($ch); 
    //fclose($handle); 

}//end function 
?>
