How do you get last modified dates of all files within a folder and compare it to a certain date? php

Question

Does anyone know a way to grab the last modified dates of all files within a folder and compare it to a certain date?

So far I have this.

<?php
    $lastmoddate = (date("Ymd", filemtime($file)));
    $todaysdate = date("Ymd", time());

    $result = array(); 
    $folder = ('uploaded_files/');     
    $handle = opendir($folder);

    foreach (glob("$folder/*") as $team){$sort[]= end(explode('/',$team));}

    while (false !==($file = readdir($handle)))
    {
        if ( $file != ".." && $file != "." )
        {
            $file = "uploaded_files/".$file ;
            if (!is_dir($file))
                $result[] = $file;
        } 
    }
    closedir($handle);


    foreach ($result as $file){
        if ($lastmoddate > $todaysdate){
            if (strpos($file, "+12:00") !==false){
                echo "$file".",".date ("h:i d/m/Y", filemtime($file))."\r\n"."<br/>";
            }
        }
    }
?>

This doesn't work as $lastmoddate = gives me the date 1969 12 31.

please learn to indent your code. it is hard as hell to read it when you trying to sort things out. -1 so far. — Your Common Sense, Nov 06 '11 at 06:05
do your files **really** have a "+12:00" part in their **names** — Your Common Sense, Nov 06 '11 at 06:07
Sorry, I've just started learning php. Will try cleaning code up. Yeah my files are called "+12:0004:31 06.11.2011-Banner.jpg" what i wanted to do was note down the TIMEZONEs in file names — user1026866, Nov 06 '11 at 06:16

PHP's filemtime() (which internally basically just calls stat() and returns only the m-time value) works on a single file at a time.

You've already got a glob() call in your script to get a list of filenames. Put the filemtime() call inside that loop to get each file's mtime, and do the comparisons in there.

Your code is not working as you've not assigned a value to $file at the point you do the initial filemtime() call, so that returns a boolean FALSE for failure, which gets converted to an integer 0 for the date() formatting. You're in a timezone that's negative-GMT, so that converts to a date slightly BEFORE Jan 1/1970, which is time 0 in UTC.

What you need is:

foreach (glob("$folder/*") as $team) { 
    $lastmoddate = filemtime("$folder/$team");
    ... date stuff ...
    $sort[]= basename($team);
}

Would This be the right way to write it out for the "date stuff" http://codepad.org/br26FKt3 — user1026866, Nov 06 '11 at 06:43

So far I can see 2 inconsistent things in your code.

you are getting lastmoddate only once, not for the existing files but for some undefined (yet) $file
you date copmparison makes no sense. Say, even if your file has been modified today, it's date never be more than today's date, so, all your comparisons will fail for sure. At least use >= or == to compare, not >

The files have been modified in a -10GMT and the website is based in a +10GMT. So $todaysdate means -10GMT. from what you can see... what would the $file value be? – user1026866 Nov 06 '11 at 06:33
