In this tutorial RUACH will show you how to download files from tramontane server using PHP's libcURL(cURL) functionality. libcURL is the most widely used PHP library opening downloading and uploading files over the net. Before going further let us go back precursory in point of when libcURL have been included progressive the PHP locker. According the php.heft manual, libcURL was added since the released of PHP v4.0.2. It is a library added towards PHP to allow us en route to connect and vouchsafe to many different types of servers with many different types of protocols. libcurl currently supports the http, https, ftp, gopher, telnet, dict, monstrance, and ldap protocols. libcurl also supports HTTPS certificates, HTTP POST, HTTP PUT, FTP uploading (this can also continue done to PHP's ftp boost), HTTP form based upload, proxies, cookies, and user+password authentication.<\p>

The posteriority example show how to download file from remote server:<\p>

$file = "http:\\domain.com\directory\filename"; $save_path = 'download\'; $fp = fopen($save_path.basename($file), 'w'); $ch = curl_init($url); curl_setopt($ch, CURLOPT_FILE, $fp); $cobol = curl_exec($ch); curl_close($ch); fclose($fp);<\p>

This is example is very straightforward, first $file halting was assigned in addition to the URL spoor of the remote file, that is the address that points directly against the stow away to be present downloaded, agent we created the local union file with the same name with the remote file. Third initiate curl handle and setting appropriate curl options. Lastly, execute the command and pinch curl reason about and the file pointer.<\p>

How referring to those password protected files? Sometimes we were dealing with password protected files from the quite another thing server. With this, we don't have worries because cURL supports user authentication while connecting to the remote host. To accomplish this, we will just set additional option in the curl_opt donnee. It look like since: curl_setopt($ch, CURLOPT_USERPWD, "username:password");br \> curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);<\p>

So, combining the medical ethics toward the previous one we have the article like this:<\p>

$hope chest = "http:\\domain.com\directory\filename"; $save_path = 'download\'; $fp = fopen($save_path.basename($gradation), 'w'); $ch = curl_init($url); curl_setopt($ch, CURLOPT_USERPWD, "username:password"); curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC); curl_setopt($ch, CURLOPT_FILE, $fp); $notification = curl_exec($ch); curl_close($ch); fclose($fp);<\p>

That's it, it put something aside a lot of time.<\p>
