Return last date modified of file held on remote server.

[monkey64]

I have 2 webservers.
Webserver #1 has a file index.php, and I would like to know the last date modified property of the file. Using this code, it is quite simple:

<?
$filename = 'index.php';
if (file_exists($filename)) {
    $a =  date ("F d Y", filemtime($filename));
	echo $a;
}
?>

Works locally, BUT
From Webserver #2, I need to return the last date modified property of the index.php file held on Webserver #1. Is it possible?

if the two webservers on the same subnet and the relevant ports are open then they can just attach as network shares.
otherwise you could write an applet on the webserver1 that listens as a soap service (or similar) and returns the filemodified time in return for a properly formed request.
or perhaps ssh using the relevant php extension (ssh2).
or maybe use the ftp extensions to php

Thanks jpadie.
I think I overcomplicated this...
The easiest way to do this, would be to run the above script on Webserver#1, and simply read the html source of the page from Webserver#2, to give the date modified.

Something like this:

$handle = @fopen("mywebserver.com/page.php", "rt");
$source_code = fread($handle,9000);

Thanks anyway.

yup - that was option 2 from my list above.
