How to unzip files on remote server using PHP script.
I tried to like this:

$zip = new ZipArchive;
$res = $zip->open('http://madm.dfki.de/demo/ip-countryside/ip2country.zip');
if ($res === TRUE) {
    $zip->extractTo($_SERVER['DOCUMENT_ROOT'].'/app/webroot/ip2country/');
    $zip->close();
    echo 'ok';
} else {
    echo 'failed, code:' . $res;
}

but, it does not work.

This error occurs:
Unable to access http://madm.dfki.de/demo/ip-countryside/ip2country.zip

How to solve this problem?

Try setting the file permission to 744 in your script. 

http://php.net/manual/en/function.chmod.php

 

change it back to 644 or whatever your correct mode is after executing the zip.

I don't think it's relating to permissions because I can download the file, so we can assume the issue isn't permission related.

 

As far as I can tell the open method requires a file that's relative to the filesystem. Basically, I don't think it allows you to open files via HTTP, FTP or HTTPS protocols because the class doesn't extend SPLFileObject.

 

I'd suggest trying to store the zip on the server using fopen (http://php.net/manual/en/function.fopen.php) then opening the ZipArchive and clear the tmp file in __destruct method.
