PHP: Checking if folder and its files in another computer? [closed]

I'm not sure what exactly do you need. For example how important is security or where files are located.

If security is not very important then you can just put folder under your website root with list permissions then you can list content of your folder on any web browser. You can make folder pass protected to restrict access but it will not be very secure but it has advantage that you will not need to open any additional ports.

You can set up FTP server or use SSH client to achieve the same effect. There is a lot of different solutions available.

You can use PHP to see if a file or folder exists on the server. You would use the following functions file_exists and is_dir . A sample code snippet is here

<?php
$filename = '/pathto/file.php';

if (file_exists($filename)) {
echo "The file $filename exists";
} else {
echo "The file $filename does not exist";
}
?> 

This is not the same as searching for a file. BTW this is bad idea to be available to public. If you want to do it, make sure no link exists to this page.

Another solution would be to use a software like TeamViewer which allows you to login into your remote computer and have full access to it. It is free for individual use. Hope it helps.
