Well, this one seems quite simple, and it is. All you have to do to download a file to your server is:

file_put_contents(\"Tmpfile.zip\", file_get_contents(\

    Try using cURL

    set_time_limit(0); // unlimited max execution time
$options = array(
  CURLOPT_FILE    => '/path/to/download/the/file/to.zip',
  CURLOPT_TIMEOUT =>  28800, // set this to 8 hours so we dont timeout on big files
  CURLOPT_URL     => 'http://remoteserver.com/path/to/big/file.zip',
);

$ch = curl_init();
curl_setopt_array($ch, $options);
curl_exec($ch);
curl_close($ch);

    I'm not sure but I believe with the CURLOPT_FILE option it writes as it pulls the data, ie. not buffered.

    Simple solution:

    <?php 
exec('wget http://someurl/file.zip');

    Since PHP 5.1.0, file_put_contents() supports writing piece-by-piece by passing a stream-handle as the $data parameter:

    file_put_contents("Tmpfile.zip", fopen("http://someurl/file.zip", 'r'));

    From the manual:

    If data [that is the second argument] is a stream resource, the remaining buffer of that stream will be copied to the specified file. This is similar with using stream_copy_to_stream().

    (Thanks Hakre.)

    A PHP 4 & 5 Solution:

    readfile() will not present any memory issues, even when sending large files, on its own. A URL can be used as a filename with this function if the fopen wrappers have been enabled.

    1. Create a folder called "downloads" in destination server
    2. Save [this code] into .php file and run in destination server

    Downloader :

    <html>
<form method="post">
<input name="url" size="50" />
<input name="submit" type="submit" />
</form>
<?php
    // maximum execution time in seconds
    set_time_limit (24 * 60 * 60);

    if (!isset($_POST['submit'])) die();

    // folder to save downloaded files to. must end with slash
    $destination_folder = 'downloads/';

    $url = $_POST['url'];
    $newfname = $destination_folder . basename($url);

    $file = fopen ($url, "rb");
    if ($file) {
      $newf = fopen ($newfname, "wb");

      if ($newf)
      while(!feof($file)) {
        fwrite($newf, fread($file, 1024 * 8 ), 1024 * 8 );
      }
    }

    if ($file) {
      fclose($file);
    }

    if ($newf) {
      fclose($newf);
    }
?>
</html>

    private function downloadFile($url, $path)
{
    $newfname = $path;
    $file = fopen ($url, 'rb');
    if ($file) {
        $newf = fopen ($newfname, 'wb');

            }
        }
    }
    if ($file) {
        fclose($file);
    }
    if ($newf) {
        fclose($newf);
    }
}
