Help me sort files by date?

[Moron]

I'm displaying the contents of a folder, with each file clickable.

 

I can't seem to get it to sort by file date, with the most current on top (descending).

 

What am I missing here?

 

 

<?php

echo "<h1>File Listing</h1>";

$content_array = array();


$path = "../FOLDER/Subfolder/";

$dh = opendir($path);

$handle=opendir($dirname);
$i=0;
while (($file = readdir($dh)) !== false) {


if ($file != "." && $file != "..")
{
       $content_array[$i][0] = $file;
       $content_array[$i][1] = date ("Y m d", filemtime($dirname."/".$file));
        $i++;
}

foreach($content_array as $res)
       $sortAux[] = $res[1];
    array_multisort($sortAux, SORT_DESC, $content_array);

    echo "<a href='$path/$file' target=\"\_blank>$file</a><br />";
}
closedir($dh);
?>

$where = "path/";

chdir($where);

array_multisort(array_map('filemtime', ($files = glob("*.*"))), SORT_DESC, $files);

var_dump($files);

Very nice!

 

One liner:

array_multisort(array_map('filemtime', ($files = array_map('basename', $files = glob("path/*.*")))), SORT_DESC, $files);

Sorry to be so dense, but I don't write PHP every day.

 

How do I integrate this into my existing code?

[Moron]

In other words, my code does exactly what I want except for the sorting.

You had a lot of unneeded code. The one line lists all files and sorts them by date descending. There are different ways to handle the path, but this should work fine:

$path = "../FOLDER/Subfolder";
array_multisort(array_map('filemtime', ($files = glob("$path/*.*"))), SORT_DESC, $files);

foreach($files as $file) {
    echo "<a href='$file' target=\"\_blank>".basename($file)."</a><br />";
}

Thanks. That's closer, but it's sorting by file name (descending) and I need it to sort by file modified date (also descending, newest on top).

Not for me it's not.

Ah. You're absolutely right I ot momentarily confused by the file names.

 

Thanks a ton!

Just for completeness, because I could see someone coming back and asking, if you want to store/use the dates as well:

array_multisort(($times = array_map('filemtime', ($files = glob("$path/*.*")))), SORT_DESC, $files);

foreach($files as $i => $file) {
    echo "<a href='$file' target=\"\_blank>".basename($file)."</a> : ".date("Y-m-d", $times[$i])."<br />\n";
}

Now there's a weird problem. I navigate to the folder in Windows Explorer and click a file, it has tons of information. I click it from this PHP page and it has just a couple of lines. It's obviously a different file, but the names match exactly.

 

This is total Twilight Zone.

 

Ideas?

What type of file?

[Moron]

Aha! For some crazy reason, it will display one file name, but point to a different one!

 

So where's the bug?

They're plain ASCII text files.

And when you open in Windows Explorer and from the browser do they open in the same app?

No, From Windows Explorer, they open in Notepad. From the browser, they open in a browser window.

 

You can hover the mouse over each file listed and look at the bottom bar of the browser, and it will be pointing to a different file name. That's why they aren't matching.

If that is really the case, then it is probably because you are using the relative ../path/etc.

Yes, I'm using a relative path. If I use the full path (http://server/folder/subfolder, etc.....), it crashes.
