[Resolved] Filesystem directory listing with date limits

[Jon7800]

I am using a script to list all folders and files in a directory. It will list the folders and files in a tree format for unlimited levels. I am wanting to modify it, so it will only list folders that have recently been added for RSS purposes.

I want to be able to set it for say...1 week 2 weeks, 1 month, etc. Can anyone help me identify only new folders by reading the date created/date modified aspect of folders? I am not worried about the files in the folders.

Thanks in advance for any help!

Here is my current code:

<?php

create_tree(".");
function create_tree($file_dir)
{
if ($handle = @opendir($file_dir))
{
$i=0;
while (false !== ($file = @readdir($handle)))
{
if ($file != "." && $file != ".." && $file != "list.php" && $file != "Judy Prep" && $file != "list.asp")
{
$list[$i]=$file;
$i++;
}
}
$dir_length = count($list);

            for($i=0;$i<$dir_length;$i++)

            {
                    if(strrpos($list[$i], ".") == FALSE)
                    {
                            echo "<br><b>".$list[$i]."</b><br>\n";

                            create_tree($file_dir."/".$list[$i]);
                    }
                    else
                    {

                            echo "<br>&nbsp;&nbsp;<a href=\"".Documents."/".$file_dir."/".$list[$i]." \" target=\"_blank\">".substr($list[$i],0,-4). "</a></b>\n";
                    }
            }
            echo "</ul>";
            closedir($handle);
    }

}
?>

$m_time = filemtime('/dir/'); // "modified" time
$c_time = filectime('/dir/'); // "changed" time
// See the manual for the difference between "m" and "c"

There is no "create" time stored (with Linux, anyway).

I want to use the filemtime() function, but I'm not sure how I would incorporate that into the code.

Basically, If the filemtime is greater than 2 weeks ago, then display the file. But I don't know the syntax to do that with an array of files. Can any one help? Thank you!

Here is the code again:

<?php
create_tree(".");
function create_tree($file_dir)
{
if ($handle = @opendir($file_dir))
{
$i=0;
while (false !== ($file = @readdir($handle)))
{
if ($file != "." && $file != ".." && $file != "list.php" && $file != "AlbumCover.jpg" && $file !=

"AlbumInfo.txt" && $file != "info.txt" && $file != "WS_FTP.LOG" && $file != "_Browse by genre")
{
$list[$i]=$file;
$i++;
}
}
$dir_length = count($list);
echo "<ul>";
for($i=0;$i<$dir_length;$i++)
{
if(strrpos($list[$i], ".") == FALSE)
{
echo "<img src=\"/images/c-list.gif\"><font face=verdana size=2><b>".$list[$i]."</b></font>\n";
create_tree($file_dir."/".$list[$i]);
}
else
{
echo "<font face=verdana size=1><a href=\"".$file_dir."/".$list[$i]." \" target=\"_blank\"><img

src=\"/images/a-home.gif\" border=\"0\">".substr($list[$i],0,-4). "</a><br></font>\n";
}
}
echo "</ul>";
closedir($handle);
}
}
?>

In order to figure out how to test for the time, etc., I needed to reformat and slightly rewrite the function. The main changes were to use an array for the skipped-over files (to shorten the function), use a "foreach" instead of a "for" loop, and use "is_dir" instead of testing for the absence of a ".". Oh, and I needed to add a couple more arguments to the function call. The age of the file is tested for and old directories are skipped over by the code in the three lines after "if (is_dir($value))". There's still a problem--empty directories. I'll leave that to you. I hope this helps you now and in your future coding.

$max_age = 30 * 24 * 60 * 60;  // Thirty days
$base_dir = '.';
$file_dir = $base_dir;
create_tree($base_dir, $file_dir, $max_age);

function create_tree($base_dir, $file_dir, $max_age) 
{ 
    $no_no_arr = array('.', '..', 'list.php', 'AlbumCover.jpg',
                       'AlbumInfo.txt', 'info.txt', 'WS_FTP.LOG', 
                       '_Browse by genre');
    if ($handle = @opendir($file_dir)) { 
        while (false !== ($file = @readdir($handle))) { 
            if (!in_array($file, $no_no_arr)) { 
                $list[] = $file; 
            } 
        } 
        echo '<ul>'; 
        foreach ($list as $value) {
            if (is_dir($value)) {
                $filepath = $base_dir . '/' . $file_dir . '/' . $value . '/';
                if ((filemtime($filepath) + $max_age) < time()) {
                    continue;
                }
                echo '<img src="/images/c-list.gif">' . 
                     '<font face="verdana" size="2"><b>' . 
                     $value . '</b>' . '</font>' . "\n"; 
                create_tree($base_dir, $file_dir . '/' . $value, $max_age); 
            } else { 
                echo '<font face="verdana" size="1"><a href="' . 
                     $file_dir . '/' . $value . '" target="_blank">' .
                     '<img src="/images/a-home.gif" border="0">' .
                     substr($value, 0, -4) . '</a><br></font>' . "\n"; 
            }
        } 
        echo '</ul>'; 
        closedir($handle); 
    } 
}
