My current attempt is to create a script that searches for updates for the webapp it works with(php). The method I thought up is to have a 'version' field in the database, and a text file with the number of the latest version on my own server(the app will be on a different server), and to compare the two. If the two aren't the same then it shows a link to update. As of now, this is what I have.

$get_updates = mysql_query("SELECT * FROM modules WHERE flag='1' ORDER BY id ASC");
while($row2 = mysql_fetch_array($get_updates))
{
$loc = ****;
if(is_link($loc))
{
$string = fopen($loc, 'r');
$data = fread($string,10);
if($data != $row2['version'])
echo "<a href=\"update.php?s=".$row2['location']."\">Update Available For ".$row2['name']."</a><br />";
}
}

I've tried this with file_exists, i've tried it with is_link, I don't know what else to try. $loc is the correct filepath, and the file reading works fine with that path. For some reason its only the part asking if it actually exists thats causing problems. This part honestly isn't extremely important, but it will be a good failsafe if i can get it working.

is_link() tests whether the file is a symbolic link and file_exists() checks if a local file exists.

If you're trying to check if a remote file exists, just test whether fopen() returns true or false.

You could make this code a bit shorter with file_get_contents() by the way.
