在更新服务器上：

 <？php 
 if（$ _GET ['pass'] == $ thepassword）{
 header -Transfer-Encoding：binary'）; 
 header（'Content-Length：'.filesize（$ zipfile））; 
 header（'Content-Type：application / zip'）; 
 readfile（$ zipfile）; 
 exit（）; 
} 
 else {
 echo'error'; 
} 
？> 
 

I'm working on my very own CMS. I put the latest updates of the CMS into an update folder on the server and the file name is update.zip.

Is there a way for me to call let's say a PHP file on the update server with a variable e.g. http://updateserver.com/update.php?pass=JDFSDH324723HDSFSDJFDSHSD3

And if the pass is correct that then the system may download the .zip file?

Or if you guys can think a better way of making an update system I'm open for suggestions :)

On the update server:

<?php
if ($_GET['pass'] == $thepassword) {
    header('Content-Transfer-Encoding: binary');
    header('Content-Length: '.filesize($zipfile));
    header('Content-Type: application/zip');
    readfile($zipfile);
    exit();
}
else {
    echo 'error';
}
?>
