[RESOLVED] Display date of last updated file

[meek]

Hi.

I'd like to display the date when my website was last updated, so I need help with a script who will run through all the files, folders and subfolders, and echo the date of the last updated file.

I have this script which seems to run through the files and folders, but it prints out the name of the last updated file. How do I do it so that it prints out the date?

<?php
    function getnewestfile($dir = "./") {
        if ($dh = opendir($dir)) {
            while ($file = readdir($dh)) {
                if ($file == "." || $file == ".." || is_dir($file)) continue;
                if (filemtime($file) > $newestfile_time) {
                    $newestfile = $file;
                    $newestfile_time = filemtime($file);
                }
            }

        return $newestfile;
    } else {
        return "";
    }
}

echo getnewestfile();
?>

Or is there an easier way?
Thanks in advance.

Make this line:

return $newestfile;

This:

return $newestfile_time;

Thanks, but it returns "1159890857"... Where does that come from?

It comes frome this line in your code:

$newestfile_time = filemtime($file);

filemtime()

The time is returned as a Unix timestamp, which is suitable for the date() function.

It's a unix timestamp, use it with the [man]date/man function 😉

Thanks a lot.

I read the manual and tried this:

 <?php
    function getnewestfile($dir = "./") {
        if ($dh = opendir($dir)) {
            while ($file = readdir($dh)) {
                if ($file == "." || $file == ".." || is_dir($file)) continue;
                if (filemtime($file) > $newestfile_time) {
                    $newestfile = $file;
                    $newestfile_time = filemtime($file);
                }
            }

        // what you had returns the file name
        //return $newestfile;
        // change it to return the file time
        return $newestfile_time;
    } else {
        return "";
    }
}

//echo getnewestfile();
echo "Last updated " .  date ("F d Y H:i:s.", filemtime($newestfile_time));
?> 

I probably didn't do it right as the date comes out as January 1, 1970. What am I doing wrong?

[bpat1434]

This:

echo "Last updated " .  date ("F d Y H:i:s.", filemtime($newestfile_time));

Needs to be this:

echo "Last updated " .  date ("F d Y H:i:s.", $newestfile_time);

Hmm, I still get January 01 1970 01:00:00. This is the code:

 <?php
    function getnewestfile($dir = "./") {
        if ($dh = opendir($dir)) {
            while ($file = readdir($dh)) {
                if ($file == "." || $file == ".." || is_dir($file)) continue;
                if (filemtime($file) > $newestfile_time) {
                    $newestfile = $file;
                    $newestfile_time = filemtime($file);
                }
            }

        // what you had returns the file name
        //return $newestfile;
        // change it to return the file time
        return $newestfile_time;
    } else {
        return "";
    }
}

//echo getnewestfile();
echo "Last updated " .  date ("F d Y H:i:s.", $newestfile_time); 
?>

Well, I ended up with this one which finally works:

 <?php
    function getnewestfile($dir = "./") {
        if ($dh = opendir($dir)) {
            while ($file = readdir($dh)) {
                if ($file == "." || $file == ".." || is_dir($file)) continue;
                if (filemtime($file) > $newestfile_time) {
                    $newestfile = $file;
                    $newestfile_time = date ("F d Y H:i:s.", filemtime($file));
                }
            }

        // what you had returns the file name
        //return $newestfile;
        // change it to return the file time
        return $newestfile_time;
    } else {
        return "";
    }
}

echo getnewestfile();
?> 

Thank you so much for your patience. 🙂

For your last non-working code, this:

echo "Last updated " .  date ("F d Y H:i:s.", $newestfile_time);

should be:

echo "Last updated " .  date ("F d Y H:i:s.", getnewestfile());
